Allie Beginner Guide — Stella Sora

Introduction

Allie is a 5-Star Aqua Vanguard Trekker built around her Main Skill, a stacking buff called Sweep Mark, and a two-phase Ultimate. Her skill descriptions are long, but in practice she plays simply: press Sweeping Rush on cooldown, build Sweep Marks, and spend them on free casts of one phase of her Ultimate, depending on the build.

She is an on-field carry. Her Support Skill works, but nothing in her off-field potentials gives that role a reason to exist, so this guide covers her main-slot builds only.

Skills

Housework Slash — Auto Attack

A five-hit blade string with high base multipliers compared to most Auto Attacks. The animations are smooth, and only the final hit carries an animation lock, which can be cancelled. Potentials in her Mark build change these hits considerably.

Sweeping Rush — Main Skill

Allie dashes to the target and deals two waves of AoE Aqua Skill DMG, triggering Aqua Mark and generating Tide. On a 7-second cooldown, this is the button you press every time it comes back.

Tide is a mark type only Allie generates. When it triggers, it deals Aqua Mark DMG and inflicts a stack of Flood for 10 seconds, up to 9 stacks. At 9 stacks, Flood is consumed to trigger Ebb, a stronger burst of AoE Aqua Mark DMG.

Each time Sweeping Rush deals damage, Allie also gains a Sweep Mark, a stacking Aqua DMG buff that lasts 12 seconds. She holds up to 3 by default, and her potentials raise that cap, make the marks permanent and spend them on free Ultimate casts.

Sweeping Slashes — Support Skill

Allie appears from the bench to perform Cycling Slashes, then a Finishing Slash that forms ice crystals, all dealing AoE Aqua Skill DMG that can trigger Aqua Mark and Tide. The damage is modest and the off-field potentials add no new mechanics, so treat it as a side effect of her kit.

Deep Sweep — Ultimate

Deep Sweep costs 275 energy, has a 40-second cooldown and comes in two phases:

• Dust Off (Phase 1) deals AoE Aqua Ultimate DMG and puts Allie in Sweeping Stance, raising her ATK for 15 seconds.
• Restore Order (Phase 2) unlocks for a short time after Dust Off. Allie leaps up and brings down a giant blade on the target for a burst of AoE Aqua Ultimate DMG, which can also trigger Aqua Mark and Tide.

Both phases matter far more than the base numbers suggest, because each of her core potential pairs revolves around casting one of them for free. Allie is immune to damage during the Restore Order animation, which makes the Phase 2 build unusually safe for a melee Trekker.

Potentials & Builds

Allie’s main-slot potentials split into two builds, each focused on one phase of the Ultimate. Both are strong, and the right one depends mostly on whether you own Suntide Willow .

Build 1 — Skill (Ultimate Phase 2)

Burst-heavy, safe and easy to build for a solid result.

Quick Sweep is the engine, and it only works in an all-Aqua squad. It raises the Sweep Mark cap from 3 to 5, stops the marks from expiring, and gives Crit Rate for every mark on top of the Aqua DMG. At 5 marks, Restore Order can be cast through the Main Skill for free, with no diminishing effect. Multi Sweep adds a blade shadow on Auto Attacks and the Main Skill that deals AoE damage and grants a Sweep Mark, on a 15-second cooldown, so free Phase 2 casts come around even faster.

Cleaver Ready shortens that blade shadow’s cooldown after every Phase 2 cast. Its own 15-second cooldown reaches 100% uptime at level 6, and in an all-Aqua squad it also adds Skill Crit Rate and Skill Crit DMG. Clothesline Stance converts all Phase 2 damage into Skill DMG and stacks Skill DMG on every Phase 2 or Main Skill cast, up to 6 stacks. With everything counting as Skill DMG, your emblems and discs only need to scale one damage type. Sweeper’s Blow raises the Skill DMG of the Main Skill and Multi Sweep each time you gain a Sweep Mark, up to 6 stacks, though it does not touch Phase 2.

You spend a large share of every fight inside Restore Order animations, which lets you ignore a good number of boss mechanics, and the free Crit stats from the potentials make the build easy to gear without specific supports.

Build 2 — Mark (Ultimate Phase 1)

A high damage floor with little gearing, but it really wants Suntide Willow.

Dusting Vortex lets you cast Dust Off for free through the Main Skill whenever the Sweep Marks are full. However you cast Phase 1, it consumes every Sweep Mark and grants the Sweep Mark buff at full strength, though you cannot gain new marks while Sweeping Stance lasts. The aim is to keep Sweeping Stance and its ATK bonus running as long as possible. Sweep Extension raises Allie’s Mark DMG during Sweeping Stance, and when her Tide lands on a target holding 3 or 6 Flood stacks, it releases a Wave of AoE Mark DMG on top of the usual triggers.

Overtime Chore, the build’s rare potential, raises Auto Attack DMG. In an all-Aqua squad during Sweeping Stance, it also enhances Housework Slash and lets the Auto Attacks trigger Aqua Mark, so Tide, Waves, Flood and Ebb all fire far more often.

Wide Blade Arc is the most important piece of the build. In an all-Aqua squad, all damage from Phase 1 and Auto Attacks becomes Mark DMG, and every 1.3% of Auto Attack DMG bonus also raises Mark DMG. In exchange, Allie’s Mark Crit Rate is cut by 100%, so this build never crits. That removes the big crit spikes, but it also means you never need a Crit line on an emblem and can stack Mark DMG alone. Pending Chore grants a stack every few Waves during Sweeping Stance, up to 4, plus an Auto Attack DMG buff of up to 3 stacks for 9 seconds. When the stance ends, the stacks turn into Sweep Marks, and since Phase 1 only needs 3 of them, Sweeping Stance stays up almost permanently.

Its damage ceiling is low and its floor is high, and the ceiling is easy to reach because the build only asks for Mark DMG, Aqua PEN and Aqua DMG. Suntide Willow is the only Aqua Trekker who buffs Mark DMG, and without her this build loses enough to stop being worth the investment.

Generic Potentials

• Sweep Dash — Holding Dodge for 0.5 seconds grants 3 Sweep Marks on a 120-second cooldown, plus Aqua DMG for every Aqua Trekker in the squad. It works in both builds and is stronger in the Mark build, which only needs 3 marks for a free Dust Off. In Boss Blitz you get two uses, one at the very start of the fight and one in the last minute, skipping the opening setup.
• Repeated Sweep — Stacking ATK whenever Allie deals Mark DMG. Both builds trigger marks often enough to keep it near full; the Mark build simply fills it faster.
• Swift Wipe — A bigger area and a higher multiplier for Phase 1. Strong in either build, and stronger in the Mark build, where Phase 1 damage turns into Mark DMG.
• Mirror Blade — Every Phase 2 cast, through the Main Skill or the Ultimate, adds a phantom blade that hits harder than a base level 10 Restore Order, and Phase 2 itself gets a higher multiplier. A key pick for Build 1, which casts Phase 2 constantly.

Purge Stance and Silent Paws grant ATK too, from Ultimate casts and from dodging or gaining a Shield, but their values are too low to pick over the potentials above.

Talents

Allie’s talents are unusually strong for a 5-Star, and Talents 1 and 2 are the ones worth chasing.

Special Cleaning Tools — Talent 1

Increases Allie’s Skill Crit Rate by 15%, and her Aqua DMG by 40% while Sweeping Stance is active. That is roughly a purple Crit Rate emblem line, limited to Skill damage, plus two purple Aqua DMG lines for free.

Sewing Kit — Talent 2

Casting Restore Order grants 36% Skill DMG for 15 seconds, and casting Dust Off grants 66% Mark DMG for 15 seconds. Either build keeps its half of this talent up all the time.

Morning Kiss — Talent 3

When any Trekker applies Aqua Mark, Allie gains 6% ATK for 6 seconds, up to 4 stacks. This is her weakest talent: 24% ATK on top of everything her kit already gives is barely noticeable.

Afternoon Sweep — Talent 4

Triggering Aqua Mark or casting the Ultimate grants 3% Skill DMG and 6% Mark DMG for 8 seconds, up to 5 stacks, for 15% Skill DMG and 30% Mark DMG at full stacks.

All-Night Watch — Talent 5

30% Aqua DMG against elite or higher-tier enemies, on the high end for a fifth talent.

Teams

Both builds rely on an all-Aqua squad, since Quick Sweep, Cleaver Ready, Overtime Chore and Wide Blade Arc only switch on with one. Every team below comes with a preset for each build.

Premium

Suntide Willow’s Mark DMG buffs and debuffs are what the Mark build is built to exploit, and Donna fills the third slot.

• Skill preset: AAAAiwAAAIIAAACgzbADAAbDgCBsADAGwGwG
• Mark preset: AAAAiwAAAIIAAACgMAbDYDDNgCBsAM2wAAwG

Donna and Teresa

Teresa takes the Support slot when Suntide Willow is not available.

• Skill preset: AAAAiwAAAIIAAAB/zDADAAbNgCBsAK2AAAxA
• Mark preset: AAAAiwAAAIIAAAB/MAbDbDDNgCBsAKxAAG2A

Iris and Teresa

• Skill preset: AAAAiwAAAG8AAAB/zbADAAaidsAABqxAAA2A
• Mark preset: AAAAiwAAAG8AAAB/MAbA7DCidsAABqxAAG2A

Freesia and Teresa

• Skill preset: AAAAiwAAAH0AAAB/zbADAAasACAMAKxAAG2A
• Mark preset: AAAAiwAAAH0AAAB/MAbDbDCsACAMAKxAAG2A

Without Suntide Willow, the Mark build has to lean on Iris or Teresa as Supports, which caps how far it can go. Build 1 loses much less in these teams.

If you own Talent 1, Build 1 no longer needs two Crit Rate 15% lines. Replace one with Skill DMG 20% or Aqua DMG 12%.

Signature Disc — Bedtime Story

Allie’s signature disc is one of the strongest Aqua discs so far, and it stays a clear upgrade even for an Aqua team that keeps Chitose on the field.

• Melody skill: When the main Aqua Trekker casts the Main Skill or the Ultimate, they gain a stack of Storybook, worth 7.5% Skill DMG for 20 seconds, up to 3 stacks. When a Trekker with Storybook deals damage, the target takes 12% more Aqua Skill DMG and Aqua Mark DMG. DMG Taken debuffs of this kind are rare in other kits, so they are worth more than another ATK buff.
• New Start Book: Raises the squad’s Aqua Skill DMG. When the main Aqua Trekker triggers Aqua Mark, they gain stacks of Reverie equal to their Storybook stacks, raising Mark DMG for 8 seconds, up to 10 stacks. It scales well with levels and only asks for two Melody types, which makes it especially good for the Mark build.
• Innocent Reverie: Gaining Reverie raises the squad’s Aqua DMG for 8 seconds, and at max Reverie stacks the main Trekker gains Skill Crit DMG.

Should You Pull?

Allie is strong, easy to build in either form, and her talents are among the best any Trekker has had. Her timing is the problem. She arrives the patch before Stella Sora’s anniversary, whose Trekker is expected to be an exclusive, flashier unit that rarely returns. She also competes for the Aqua Vanguard slot that many accounts already filled with a built Chitose, and switching means redoing emblems for a gain in damage.

The Mark build needs Suntide Willow to shine. If you do not own her, or you already have a strong Aqua team, wait for the anniversary livestream on October 19 to see the anniversary Trekker before committing. If you like Allie, pull for her anyway: the meta has little power creep, and any well-built Trekker clears all the content.
