Mongil: Star Dive’s Version 1.4 update, “Ashen Cradle Lullaby”, arrives with maintenance on 9/29 (Tue) 23:30 – 9/30 (Wed) 03:30 (UTC). It opens Episode 7 in the new Gaba Archipelago, adds the 5★ character Isabella and the Legendary Conquest monster Sorin, and starts the Half Anniversary — including a guaranteed 5★ Permanent Character for every account that has done its first recruitment.
Before the Maintenance
- Redeem codes
NEWEPISODE7andDIVEWITHISABELLAeach give Key ×150, Compass of Promise ×3 and Premium Salmon Purée ×10, and both expire when maintenance begins, at 9/29 23:30 (UTC). - Legendary Conquest switches from Reginula to Sorin and the attempt count resets, so spend your remaining attempts first.
- The Dimensional Rift “Spotlight Shining on Desire” and the current Monster Race season end on 9/29 at 23:59 (UTC). The three free weekly Rift Entry Tickets are refilled when the new season starts, so use the ones you have. Race Badges and Track Mission rewards change with the reset.
- The Bunny Showgirl’s Eternal Encore and Unending Finale recruitments, and the Bunny Showgirl Relay products in the shop, end with the maintenance.
Free Rewards
- “A New Friend for a New Journey” guarantees one random 5★ Permanent Character. It goes to everyone who has completed their First-Time Recruitment, claimable from the end of maintenance to 11/10 (Tue) 23:59 (UTC). New accounts get the same guarantee differently: from 1.4, the First-Time Recruitment itself always yields a 5★ Permanent Character.
- Maintenance compensation: Starlight Crystal ×300 and Glimmering Stardust ×2, by mail to Divers who log in between the end of maintenance and 10/2 (Fri) 14:59 (UTC).
- Netmarble puts the 1.4 and Half Anniversary rewards together at over 150 recruitments.
New Characters and Recruitments
Isabella, the “Lazy Genius Engineer”, is the new 5★ character, and Chloe joins her in the Episode 7 story.
The Half Anniversary recruitments run in two parts:
- Part 1:
Mina
and
Narae
, with their artifacts. - Part 2:
Esther
and
Nagi
, with their artifacts. - Promise of Choice, a new recruitment that lets you pick the 5★ Permanent Character you want. Netmarble’s advice is to claim the free guaranteed 5★ above before using it.
Legendary Conquest: Sorin
Epithym: Sorin is an Oriental serpent built around large-scale fights and attacks that use elements and space. Sorin resets every Monday, like Reginula, and alternates with it after two opening weeks:
| Week (UTC) | Legendary Monster |
|---|---|
| 9/29 – 10/4 | Sorin |
| 10/5 – 10/11 | Sorin |
| 10/12 – 10/18 | Reginula |
| 10/19 – 10/25 | Sorin |
Elemental Sanctum
A new challenge mode of bosses fought one after another. You choose restrictions that raise the difficulty — hidden boss HP, bosses that heal over time — to reach higher stages and better rewards. Clears pay a currency for buying more restrictions, and the stage you reach grants Elemental Blessing, which raises elemental DMG and levels a new Passive Trait for each character.
Both apply account-wide, so they carry into every other mode. Every character gets a Passive Trait regardless of Awakening Stage; Netmarble’s example is a DEF Reduction effect for
Verna: Summer Dive!
.
Balance Changes
The 5★ Permanent Characters
Gabi
,
Sangun
,
Flare
and
Penny
are adjusted, along with Esther, Nagi and Verna: Summer Dive!. Skill DMG increases are among the changes.
