- Basic Attack (Goat Knife): Swings a cheese knife, dealing damage to enemies in a straight-line range.

While the mark is active, a short press dashes to the mark's location, damaging nearby enemies and reducing their healing received by 50% for 6 seconds. A long press retrieves the mark, dealing damage and inflicting Bleed for 3 seconds. If the mark was on a wall, it recovers 50% of the skill's cooldown.
- Ultimate (G.O.A.T): Deals damage to enemies in a fan-shaped range, then reduces their healing received by 50% for 4 seconds and retreats. If the target's current HP is at or below 50% of max HP, deals increased damage.

[Balance]
◼︎ Buffs
- Madeleine Cookie
- HP increased by 10%: 6,500 → 7,150
- Special Skill 2 damage reduction increased: 10% → 20%
- Design intent: We judged that Madeleine Cookie, who holds the front line in the current combat meta, lacked sufficient toughness and stability. We increased base HP and the special skill's damage reduction so it can more solidly serve as a sturdy shield for allies.
- Strawberry Crepe Cookie
- Ultimate's shared Waffle Robot HP increased: 4,100 → 4,920
- Ultimate's shared Waffle Robot attack speed increased: 100%
- Ultimate's shared Waffle Robot movement speed increased: approx. 30%
- Design intent: We broadly increased the stats of the Waffle Robot summoned by the ultimate so it can hold the front line and pose a meaningful threat to enemies. The large boost to mobility and attack speed is expected to significantly strengthen its pursuit ability and expected damage output.
- Dark Choco Cookie
- Basic Attack damage: 750 → 825
- Design intent: Dark Cacao Cookie's basic attack stood out for its excellent accuracy and range, but even accounting for that, its damage output felt somewhat lacking. We increased the basic attack power so it can apply clear pressure on opponents in combat and make better use of its solid fundamentals more threateningly.
- Blueberry Pie Cookie
- HP increased by 10%: 3,300 → 3,630
- Basic Attack damage: 1,094 → 1,203
- Design intent: We increased HP to address survivability issues stemming from the risk involved in using the special skill and ultimate relative to overall toughness. We also judged that basic attack firepower was insufficient even accounting for its long range and decent projectile size, so we raised the damage as well.
◼︎ Nerfs
- DJ Miya
- Maximum speaker placement distance reduced: 8M → 7M (12.5%)
- Basic attack damage: 400 → 360
- Design intent: The speaker's long placement range made it somewhat unreasonable for opponents to be caught off guard with no way to react. We reduced the placement distance to create an appropriate entry risk, and also slightly lowered the basic attack power, which was judged to be somewhat excessive, to adjust the overall value of related skills.
◼︎ Other Cookie Adjustments
- Improved Strawberry Mochi Cookie's special skill so it is always used in the direction of the joystick input.
- Improved Strawberry Mochi Cookie so that when using the ultimate with auto-targeting, it now faces the target direction until right before the skill is fired.
- Changed so that non-damaging debuffs no longer block natural HP regeneration.
[Other Improvements]
- Fixed an issue where Brie Cheese Cookie's special skill cooldown reduction on basic attack hit was being applied incorrectly.
- Added UI presentation and sound improvements so it's easier to notice when there is no ammo left when using a basic attack with an empty magazine.
- Improved so that attack indicators are always displayed on top.
- Slightly increased damage number font size to improve combat readability.
- Improved so that healing numbers are displayed from multiple points.
- Fixed the conditions for resetting natural HP regeneration.
- Slightly reduced the cancel area of the skill joystick to improve control responsiveness.
- Improved so that when resizing the skill UI in control settings, the skill joypad and skill-use cancel area resize together accordingly.
- Changed so that the shared mode UI (top HUD) no longer allows checking only an enemy's ultimate charge ON/OFF state.
- Improved so that owned items can be equipped even if you only own some items from a costume set.
- Improved the sort order of various items on the customization screen.
- Improved the sort order of various items on the profile screen.
- Competitive weekly schedule times are now displayed in the time zone matching the player's own region.
