Fuyuka Beginner Guide | Stella Sora

Introduction

Fuyuka is the first limited 5 Star Ignis Vanguard Trekker with a focus on using ammo to enhance her Auto Attacks to improve their damage and effects. As of the writing this guide Fuyuka currently is the Trekker with the most versatility in her builds and also teams. Not only that, she is currently the 2nd best DPS just behind Shia . Which is an amazing feat seeing how strong Shia is. With this guide you will learn what Fuyuka's skills do and which ones to level first, Talents, Builds, Emblems and Teams.

Skills

So let's get through her skills beginning with her Auto Attack.

Blitz Combo - Auto Attack

5-hit fast auto attack sequence that hit for a solid amount of damage with splash AoE damage to enemies behind the target hit.
When Fuyuka has ammo this 5-hit sequence instead turn into a 3-hit sequence named "Fiery Punches" that deals more damage while also having a higher AoE ranged but being slower. This keeps the splash AoE damage from the "Blitz Combo".

This will be the bread and butter of your time playing Fuyuka. Every part of her potentials interact with her auto attack. From simple damage increases the build defining potentials they all lead back to this auto attack sequence. If you are wondering how Fuyuka gets ammo then let's get to her skill

Ignis Infusion - Main Skill

2-hit skill that deals AoE damage
Sets the ammo counter to 3 by default (this can be changed with potentials further discussed in the guide)
Triggers "Ignis Mark" that deals AoE damage to surrounding targets.

This is how you are getting the ammo to use the "Fiery Punches" mentioned before. Most of the times you will be using this skill as soon as it comes out of cooldown to get as much ammo as possible to get as many "Fiery Punches" possible to increase Fuyuka's damage capabilities. Although a few warnings, while using this skill you are not immune to damage and it's decently long animation so you can easily take damage midway through using it. Luckily, You can cancel the skill in the middle of the animation by dodging. Although you need to be careful while doing this, if you dodge too early into the animation you won't get your ammo which is key to making Fuyuka work and if you dodge in the middle of the animation you won't get the 2nd hit of the skill (this is not as a big of a deal but definitely something to keep an eye out and decide if taking that damage is worth the 2nd hit or not).
Another point to make is that the mark damage is nothing to scoff at. As of the writing of this guide Fuyuka's "Ignis Mark" is the 2nd highest damaging mark at 172% Attack Scaling behind Shia's "Lux Marks" being at 241% Attack. So these can stack in the long term. So more reason to maybe not cancel the skill

Eruption Punch - Support Skill

11-Hit Skill that does stationary AoE damage
Triggers "Ignis Mark" that deals AoE damage to surrounding targets.
Niche

As a Vanguard, Fuyuka will rarely see usage outside of teams where she is the main on-fielder Trekker. Which makes her support skill not really a point of focus for her. Could you still technically use her? More than likely yes. But currently there is no Trekker on-field that would make Support Fuyuka a good option, making any benefit that this team would have fall extremely behind Fuyuka on-field. So there for I won't go into detail for this playstyle in this guide. If a future Trekker allows this playstyle to be played more efficiently I will update this guide and go into detail.

Blaze Unsealed - Ultimate

7-Hit Ultimate with extremely HIGH scalings
Triggers "Ignis Mark" that deals AoE damage to surrounding targets.
Long duration.

Fuyuka's ultimate is quite possible the most ridiculous ultimate to read through. All because of it's ridiculously high scalings. Making it the hardest hitting skill / ultimate currently out in Stella Sora. However it comes at the cost of it being a very long animation. So there are times where using the ultimate ends up being a DPS (Damage per second) loss , specially on Boss breaks due to them only lasting 10 seconds and the ultimate lasting just slightly longer. Making it so you can't fully use the ultimate's damage in that break.
Although even if that's the case this ultimate still has many usages outside of it's damage. Such as the fact that while using you are fully immune to damage and crowd control (Stuns, Knockbacks, etc...) which can be very handy when it comes to dealing with boss mechanics that deal high quantity of damage, allowing you to keep damaging boss where normally you wouldn't be able to.

Skill Upgrade Priority

Now that you are aware of what Fuyuka's skills do which ones should you upgrade first? Very simple!

Skill > Auto Attack > Ultimate | Ignore Support Skill

The reason we are going Skill first here is due to Skill levels directly increasing the Core Potentials (The pink ones) scaling, which for Fuyuka, ends up being her main source of damage. So increasing this will allow you to get the most out of her. Afterwards go for her Auto Attacks which is her 2nd source of damage and your main damage while on downtime(when you have no ammo / skill is on cooldown). Last you will go Ultimate, while it can definitely deal ridiculous amounts of damage it contains the issue of it being the highest energy costing ultimate at 345 Energy, which makes it not a reliable source of damage without putting a decent amount of resources into ultimate dedicated stats (Charge Efficiency, Ultimate DMG% ) on your emblems and changing your build through potentials that focus only on your ultimate. Which is not ideal specially when starting out. For your Support Skill it's the same reason as I said when I explained the skill itself. As you will almost never use Fuyuka as a Support there is 0 reasons to upgrade this skill outside of Niche, 4 Fun playstyles. Which most players will not engage with.

Talents

Talents aka Duplicates. Are usually not that impactful in Stella Sora (that being good or bad is up to you). However Fuyuka is one of the few Trekkers which has a few Talents that are actually great so let's get through them

Natural Strength

After Fuyuka triggers a "Ignis Mark" she increases her own Crit Damage by 40%

This is quite possibly one of the strongest Talents currently out. This in effect is just always active because you are by default always triggering "Ignis Mark" that being with your Auto Attacks (with potentials), Skill or Ultimate. Making it just a solid increase in damage for Fuyuka and if I were to ever mention a Talent that I'd recommend obtaining if you really like Fuyuka. This would be it.

Fist of Awakening

When casting Skill increases her Ultimate Damage by 33% up to 2 stacks.

One of the most common types of Talents. A simple Ultimate Damage increasing buff. Not really anything special about this. Unless you are going to directly target your Ultimate with your builds this just ends up being a nice but not really noticeable buff for Fuyuka. Definitely not worth going for specifically.

Peerless Might

25% Ignis Damage increase after using Ultimate for 20 seconds.

This one isn't bad but it's also not amazing. Due to the buff immediately starting after casting her ultimate. 10 seconds minimum are fully dedicated to her ultimate. Leaving the remaining 10 seconds for her normal skill rotation. Which isn't a lot of time for a not amazing increase in damage. For example a purple Ignis Damage % increase stat in an emblem is 12% and you can have up to 3 of these for 36% Ignis Damage increase. There for not exactly a great Talent to go for specifically as well.

Two Punch Hero

After any ally applies an "Ignis Mark", Fuyuka's Ultimate DMG is increased by 66% for 10 seconds.
One Punch Man reference.

Again, another Ultimate focused Talent which even if we ignore the fact that it can't fully buff the entire Ultimate's hit count. It's only a mere 66% increase. Again for comparison a single purple Ultimate Damage % increase stat is 40% which you can also have 3 of for a total of 120%, nearly doubling what this talent gives while not having any conditions to trigger it's effect. Which makes this Talent Fuyuka's worst Talent.

Learned from the Best

Ignis Damage increase to Elite or higher tier targets by 24%

Classic Vanguard Talent 5 style buff. Just an overall damage buff to bosses that most 5 Star Trekkers currently have. With only one deviating from this style (*Cough* Shia....). Nothing special to really say about this Talent. Personally it's not really worth getting it since it's a conditional damage increase and not by a crazy amount either. Again like previously mentioned you can obtain similar quantity of Ignis Damage% through Emblems. So I don't recommend getting it overall.

Overall when it comes to Talents. If you don't mind spending the extra pulls or if you are near to sparking (120 pull claim) I'd get her Talent 1 but that's only if you really wanna take your Fuyuka to the next step and push leaderboard results. But that's where I'd stop Talent Wise.

Builds

Fuyuka like I mentioned in the introduction, is one of the few vanguards where almost all of her builds are great and decently competitive. So you can't really go wrong with any of the builds mentioned here and most of the times can be chosen out of preference for playstyle, comfort and some of the builds having minor team preferences that will be mentioned on the team section of the guide.

Kitty Punch Build

Highest Single Target Damage build
High Attack Speed
Simple to play
Ignis Mark Trigger

This build focuses on getting as many "procs" (Activations) of the Kitty Punch effect, which is whenever you hit an enemy with your Skill "Ignis Infusion" it marks them with a "Paw Print" and then when you hit an enemy that has a "Paw Print" with an Auto Attack they will take additional damage that can trigger "Ignis Mark" and to take advantage of this effect and increase it has much as possible you will want the following Potentials.
Multi-Shot to remove the slow hitting "Fiery Punches" instead making you consume 3 ammo once to deal a burst 2-hit High ATK% scaling damage while also increasing your ATK Speed% while you have no ammo. (WARNING: When using this potential You can technically cancel the enhanced auto attack causing it to not go through and instead making you use "Fiery Punches" instead. So as a precaution avoid dashing midway through the animation.)
Blast Pursuit to capitalize on the multi hit playstyle to give additional burst of single target damage after 4 hits on the same target. This Potential is a MUST HAVE MAXED for this build**.** If you don't get it at level 6 the build will be severely weakened!
Finishing Blow to get a consistent Ignis Damage% Buff. Specially on game modes where bosses have Infinite HP or multiple Bars of HP, you can take more advantage of this buff, such as Boss Blitz. Because the HP% condition is not based of the Total HP of the target but instead the HP Bar%. So as long as that bar is below 70%. You will get this buff activated.
Combo Punch to increase "Kitty Punch" and "Blast Pursuit" damage because both of those Potentials scale off Skill Damage so it ends up being a great increase to them while also increase your ATK Speed% to get more hits out.
Inertial Punch just as an additional buff to your "Multi-shot" damage, specially since you will be using that enhanced Auto Attack once every 11 seconds. This buff will always be up for your next "Multi-Shot" enhanced Auto Attack.
Swirling Counterattack is an overall decent buff to have if you are going Mono Ignis (Team of only Ignis Characters) but if you are not this Potential is useless. So ONLY pick this if you are going Mono Ignis.
Bold Challenge is another generic ATK buff that only works after hitting Crits on an Elite or Higher tier enemy (AKA, Bosses or Mini-bosses). While it does have a limiting condition it won't be much of an issue due to just the shear amount of hits you are throwing out you will always get use out of this potential.

Overall with this build you will just want to lock in on the enemy and hit it as many times as possible to really get as many "Kitty Punch" and "Blast Pursuit" procs because they are truly the main source of damage. Ideally you will want all of the potentials at level 6 but if "Inertial Punch", "Swirling Counterattack" and "Bold Challenge" aren't maxed it won't be the end of the world.

Disks (Kitty Punch Build)

Luckily for Fuyuka she has a wide range of possibilities for Disks and all of them are pretty equal to each other so realistically you can use any of the following disks but I will put them in a priority order.

Fireworks (5 Star Fuyuka Signature Disk) - This one speaks for itself. It gives everything Fuyuka needs going from Auto Attack Damage increase to Squad Ignis Damage Increase with an added Squad Ignis Skill Damage Increase but if that wasn't enough it also give her personal Skill Damage Increase which is exactly what "Kitty Punch" wants!
Fist of Courage (5 Star Event Disk) - Again this disk was released for Fuyuka's event so no wonder it works great on her. While the main melody skill, the Ultimate Damage increase, won't matter much for this build. The remaining definitely does by once again increasing Squad Ignis Skill Damage it also has an additional effect of whenever an Ignis Squad Member uses a skill, ALL Ignis Trekkers in the Squad gain ATK%. For the last buff a small Auto Attack Damage bonus which is not bad since it still does help your "Multi-shot" hits.
Voyage Blueprint (5 Star Finale Echoing Event Disk) - This disk is just overall ridiculously strong. Offering Survivability by giving a shield on Skill Cast and whenever your Main Trekker gains a shield you gain a Squad Ignis Damage increase just casually and if all of that wasn't enough the last buff is a Skill Damage Increase as long as you are above 50%HP which won't be hard to maintain due to having a consistent shield with the first part of this disk!
Mystic Brushstrokes (5 Star Chixia Signature Disk) - While Chixia herself as plenty of issues her Signature disk does not! Giving a solid Squad Ignis Damage Increase by default and whenever an "Ignis Mark" is triggered it gives the entire squad Ignis Skill Damage increase. It also gives a weaker Ignis Skill Damage increase that gets doubled if you are using Chixia on your team since she's the only Trekker that applies the "Ignite" effect. But to end it off it also gives a decent ATK buff to the Main Trekker whenever an Ignis Support Trekker uses it's skill.
One Shot, One Down (5 Star Cataclysm Survivors Disk) - Overall one of the strongest Cataclysm disks, having a strong set of effects such as a Squad Ignis Damage increase, Increased Ignis Damage to enemies vulnerable to Ignis while also reducing the damage that the Main Ignis Trekker takes by 10%. But what makes this Cataclysm Disk better than it's piers is that it's last buff doesn't require any specific conditions to be met to get it's buff. All you need is wait and over time you will gain a stacking ATK% which will make your damage ramp up over time.
Twin Moon Mischief (4 Star Gacha Disk) - This disk is more of a slot-in incase you are missing one slot by not having more of the 5 star options. Overall 4 Star disks aren't great. They usually have niche condition to get their buffs and Twin Moon Mischief is no exception but it's better than the remaining 4* disks by having a default Skill DMG increase which if you are above 80% HP increases further, with the 2nd buff being that whenever a Support Ignis Trekker is on-field it increases the Main Ignis Trekker Skill Damage. While the HP requirement can be easy to mess up, specially in Boss Blitz or other hard content. This ends up being the best option for being the most consistent one.

Reload Build

Highest AoE Damage and Range
Consistent Damage

This build focuses on getting 9 Ammo to get as many "Fiery Punches" possible for high scaling Auto Attack Damage Scaling attacks to make a consistent DPS build that excels at AoE content such as Cataclysm Survivors or multiple monster Boss Fights. To truly get the most out of this build you will want these Potentials.
Double Strike to enhance your "Fiery Punch" by making them deal additional damage. This ends up stacking a lot just because you end up doing so many of them.
Thunder Punch to add a high ATK% additional hit to the 3rd Hit of your "Fiery Punch" that scales of your Auto Attack Damage. (WARNING: This makes your 3rd "Fiery Punch" have an additional animation so be careful to not accidently cancel this additional hit of damage by dodging before it goes off).
Pyro Mark for an increase in your "Fiery Punch" but more importantly, allowing them to trigger "Ignis Mark" to get another way to trigger them and by effect increasing your damage output.
All-Out Effort for another increase to your "Fiery Punch" although keep in mind this buff scales of "Fiery Punch" hits so your initial "Fiery Punch" won't have the maxed out stacks. But the last "Fiery Punch" will have a 328% Damage Increase (Assuming Potential Level 6).
Finishing Blow for the same reason as the previous build. To get a consistent Ignis Damage% Buff. Specially on game modes where bosses have Infinite HP or multiple Bars of HP, you can take more advantage of this buff, such as Boss Blitz. Because the HP% condition is not based of the Total HP of the target but instead the HP Bar%. So as long as that bar is below 70%. You will get this buff activated.
Inertial Punch / Swirling Counterattack. These 2 are replaceable with each other. The deciding factor being if you are playing Mono Ignis or not. If you aren't then pick up "Inertial Punch". If you are pick up "Swirling Counterattack"
Bold Challenge again being just a generic ATK% buff that's nice to have when facing elite or bosses enemies

Overall with this build while you will be slightly behind in direct single target DPS when compared to the "Kitty Punch" build this one allows to be more comfortable in AoE content such as Cataclysm Survivors and Menace Arena. But this doesn't mean this build can't do good single target damage, not at all! This build is more than capable of being used on Boss Blitz and get 7 Stars. Which is all you need to get all the rewards.

Disks (Reload Build)

One issue this build currently has is the lack of disks that support Auto Attack Increase. With only realistically Fuyuka's signature supporting it. So the Disk option remain mostly the same as the previous build. With only priorities shifting. Since they are mostly the same reasons I will only point out the key factors that makes them more important in this build and not their overall value as that as already been done on the "Kitty Punch" section

Fireworks (5 Star Fuyuka Signature Disk) - Again. It gives everything Fuyuka needs going from Auto Attack Damage increase to Squad Ignis Damage Increase with an added Squad Ignis Skill Damage Increase but also gives Skill Damage which "Reload" can get use off.
Fist of Courage (5 Star Event Disk) - Again this disk was released for Fuyuka's event so no wonder it works great on her. Increased Squad Ignis Skill Damage it also has an additional effect of whenever an Ignis Squad Member uses a Skill, ALL Ignis Trekkers in the Squad gain ATK%. For the last buff a small Auto Attack Damage bonus which is not bad since it still does help your "Reload" build.
One Shot, One Down (5 Star Cataclysm Survivors Disk) - This disk goes up in value due to it working better for Auto Attack than the ones below. Overall one of the strongest Cataclysm disks, having a strong set of effects such as a Squad Ignis Damage increase, Increased Ignis Damage to enemies vulnerable to Ignis while also reducing the damage that the Main Ignis Trekker takes by 10%. But what makes this Cataclysm Disk better than it's piers is that it's last buff doesn't require any specific conditions to be met to get it's buff. All you need is wait and over time you will gain a stacking ATK% which will make your damage ramp up over time.
Voyage Blueprint (5 Star Finale Echoing Event Disk) - Remains ridiculously strong just due to it's survivability increase but also due to it's simple condition to obtain ATK% and Ignis Damage Increase
Mystic Brushstrokes (5 Star Chixia Signature Disk) - This disk losses most of it's value on the "Reload" build due to the fact it won't be able to buff the Auto Attack Damage. It's still a valid stat stick with decent enough buffs.
Scorching Night's End (4 Star Gacha Disk) - This is what would replace Twin Moon Mischief. This ends up being the better 4 Star option in this base because it's the one that gives the most useful stats with no awkward conditions to meet. Just trigger "Ignis Mark" and you get a Squad Ignis Damage Increase and you also have a default increase ATK% to Ignis teammates with whenever an Ignis Trekker uses a skill, All Ignis Squad members gain Ultimate Damage Increase.

Ultimate Burst

Highest Burst
Big Break Value
Niche

While I'm giving this it's own section this is essentially just "Kitty Punch" build but with some minor switches to Potentials. This build is not exactly recommended as it's very niche and not worth putting resources into it. But it can be fun to play and see the big numbers and also whenever a Boss Blitz effect buffs Ultimate Damage. So to maximize it you will want the following Potentials:

Again like I said you will want the "Kitty Punch" Core Potentials to help your downtime between ultimates and since I already talked about the Kitty Punch Potentials I'm only going to mention important factors for this build.
Peak Condition / Ironfist Blow is a MUST HAVE LEVEL 6. It's kind of obvious since they are direct ultimate buffs but without them at that level you are losing a significant amount of damage.
Blazing Heart is not necessary but nice to have. This is mostly due to it's conditional nature of the first punches of your ultimate requiring that they Trigger "Ignis Mark" to obtain it's maximum value and some of the times that Fuyuka uses cannot get maximum value out of it. So if you can't find it in your run don't sweat it too much!

Disks (Ultimate Build)

Surprisingly this build does get more support than the Auto Attack Build but this doesn't mean new disks will be added. With only a minor priority change being added here and an honorable mention of a disk

Fireworks (5 Star Fuyuka Signature Disk) - Again. It gives everything Fuyuka needs and even if it doesn't directly buff your ultimate damage. It is there to help with your downtime whenever you aren't using your ultimate.
Fist of Courage (5 Star Event Disk) - It gives Ultimate Damage Increase while also support your downtime by buffing Skill DMG.
Voyage Blueprint (5 Star Finale Echoing Event Disk) - Goes back up in priority due it's main stat being Ultimate DMG giving a solid 40% Ultimate damage increase just by default.
One Shot, One Down (5 Star Cataclysm Survivors Disk) - This disk goes up in value due to it working better for Auto Attack than the ones below. Overall one of the strongest Cataclysm disks, having a strong set of effects such as a Squad Ignis Damage increase, Increased Ignis Damage to enemies vulnerable to Ignis while also reducing the damage that the Main Ignis Trekker takes by 10%. But what makes this Cataclysm Disk better than it's piers is that it's last buff doesn't require any specific conditions to be met to get it's buff. All you need is wait and over time you will gain a stacking ATK% which will make your damage ramp up over time.
Mystic Brushstrokes (5 Star Chixia Signature Disk) - This disk is fine in "Ultimate" Build because it can still directly support the downtime with it's Skill Damage Increase. If even it can't directly buff Ultimate Damage.
Scorching Night's End (4 Star Gacha Disk) - This is the best option for a 4 Star, possibly competing against Chixia Signature due to the fact it buffs both Skill Damage and Ultimate Damage.

Teams

Time to go over all the possible teams you can use with Fuyuka, keeping in mind you can use any of these with any build so you don't have to worry too much about what build to use with what team. One thing to note although is that every team will include Flora . She is a must have team member for Fuyuka. She just offers everything Fuyuka needs shine. From Crit Rate and Crit damage buffs, to "Ignis Mark" application. So let's first talk about her potentials. I won't go into detail what Flora does. I'll leave that for a direct guide for her later in time. What I will say is that you want to at least get her Support Skill to Level 7 to get most of the buff that it offers.

Flora has two potential builds you can for depending on your level of investment on Fuyuka. One if you are high investment, meaning multiple Crit Rate and Crit Damage Emblems and the other for low investment with minor emblems.

Low Investment Flora

This build focuses on making enemies take Increased Ignis Damage. Making it more consistent and less reliant on RNG crits
Post-Credits Scene is here to help with mark application in case you notice you aren't getting enough, although it is replaceable with Lethal Inferno for more Ignis Damage Taken for example whenever you want more bursts on a boss Break or if you already get enough marks.
While there's no specific must have, Perfect Acting and Guest Performer are nice to have at Max Level.

High Investment Flora

This build is better used whenever you can more consistently get Crits, either by using Chixia or having Crit Rate stats on your Emblems.
This will do more damage than the previous build but at the cost of consistency.
Reinforced Impression and Foreshadowing Verification are big whenever maxed to take full advantage of Crit.

Now for the 3rd slot for Fuyuka teams. For these I'll only go over 1 build for each Support as they are somewhat Universal and will work with any build except one member which I'll mention when we get to them.

Ann Support

So far my favorite support for any hyper carry style team. She just offers so much for team. ATK% buffs, Shielding, Projectile block. It's insane that this character is a 4 Star to be honest. She's just a solid teammate and yes I do prefer her over Chixia for the 3rd slot on a Fuyuka team. Since she plays better off on lower Investment teams, just like Flora you will want her Support Skill at Level 7. Okay then the potentials you will want on Ann are the following.

This will give you the most attack possible while also giving a comfortable shield. Focus on getting Windgate Barrier and Violent Current maxed to maximize ATK% buffs.
Leveraged Boost should only be picked if the content you will be using Ann contains projectiles that can be blocked by the wind walls to offer the gigantic ATK% boost.
Speed Surge can be picked on any build but is better of on "Kitty Punch" build since they get more out of Attack Speed bonuses.

Chixia Support (Low Investment)

As much as I'd like to slander Chixia she is still very much the current intended 3rd slot for Ignis teams and she does fine most times although she has 2 builds depending on your level of investment of your Fuyuka. With the low investment potentials being the following.

You might think it's odd to mix Dragon and Tiger but the objective here is to just help with mark application and damage with little investment into her potentials allowing you to focus on the remaining characters potentials.
Keep in mind Chixia has a somewhat long skill cast time. So avoid using her ultimate right away after skill as it can cancel summoning the minions.

Chixia Support (High Investment)

This is the build you'd want to go whenever your Fuyuka has more investment into Crit stats, just like the flora build before. As this next set of potentials focus a lot of the buffs that Chixia's minions give such as Crit Rate.

Focus on getting Ink Sigil: Horn Call and Ink Sigil: Barrier Construct to level 6 to get those buffs maximized.
When playing this build you will want to keep in mind where your dragons are being summoned as their position will matter for this build since you want to stay near them to gain the buffs of Ink Sigil: Raid.

Tilia Support (Mark Damage)

Using Tilia is definitely a way more niche teammate and most of the times you will be using your Tilia on your Shia teams. But in case you don't have Shia , Tilia can definitely fit the third slot great for a Mark Damage build. So for that you will want the following potentials!

You will want to max out Blinding Beam. As it will give your marks as humungous burst of damage which will be key for the Tilia Build
You can slot in the Defensive options such as Knight Oath: Chalk Armor if you see that you are losing a lot of HP during fights but if you think you can lock in and dodge the damage then it's not necessary

Emblems

Emblems are the main gate for investment in a Trekker and being essential to maximize their damage. But they can be somewhat complicated due to each emblem slot having their own set of stat limitations. Luckily though, Fuyuka's emblems choice are somewhat simple so let's check them.

Emblem Level 70 - Ignis Damage | Ignis Pen | Crit Rate | Skill Damage / Auto Attack Damage / Mark Damage / Crit Damage

For Level 70 the first 3 stats is the main go for stats. With the last 3 being build dependent. If you are "Kitty Punch", then Skill Damage, if you are "Reload" then Auto Attack Damage and if you are playing Tilia, Mark Damage will be the go to . But if you prefer a more generic stats that can help either build you can go Crit Damage
Emblem Level 80 - Ignis Damage | Ignis Pen / ATK% | Crit Rate | Main Skill Level +2 3 / Skill Damage / Auto Attack Damage / Mark Damage / Crit Damage

Similar stats for level 80 with the Main difference being that the Level 80 emblem allows you to get additional levels on your Main Skill to better improve your Core Potentials and the skill's damage itself. But again if you aren't able to find it you can still slot the other stats. Ignis Pen here can also be replaced with a generic ATK% stat buff if on the first Emblem you already have a Purple Ignis Pen Stat. This applies to the previous emblem as well.
Emblem Level 90 - Ignis Damage | ATK% / Skill Damage / Auto Attack Damage / Mark Damage | Crit Rate | Blast Pursuit Level +2 3 / Thunder Punch +2 3 / Finishing Blow +2 3

Again mostly the same for Level 90 Emblem Stat wise with the main difference being the addition of direct potential levels and the removal of the Ignis Pen stat. Which the ideal would be Blast Pursuit for "Kitty Punch" build**, Thunder Punch** for "Reload" build and Finishing Blow as the generic "work on any build" stat.

Overall Thoughts

Fuyuka is an amazing DPS that requires little to no effort to see success with. I can see her staying in meta for a good chunk of time as it's unlikely for another Ignis Vanguard to be released any time soon which allows a lot of breathing room for Fuyuka to just do her own thing. Also it's possible that she gets stronger with the release of a stronger 3rd slot Ignis Support that replaces Ann / Chixia / Tilia to truly get her to an even higher step on the meta.

Thanks for reading!
And I hope you enjoy playing Fuyuka!
