Cool Mint Cookie Guide: Skills, Synergy & Best Teams

Cool Mint Cookie is the first new Cookie added to CookieRun: Crumble after launch, arriving with the August 13, 2026 update. She is an SSR Water Cookie that plays as a frontline charge-style attacker, and she brings the game's first excavation mechanic: drilling through the battlefield, knocking enemies around and summoning skulls from the ground.

Cool Mint Cookie at a glance

Implant Excavation — skill breakdown

Cool Mint's skill, Implant Excavation, works in two stages:

1. Drill stab — she stabs forward with her drill, dealing damage to enemies in front of her.
2. Ground dig + skull summon — she digs up the ground between enemies, knocking them back while dealing damage, then summons skulls from the excavated ground to keep fighting.

The skill is telegraphed by her forward dash (fixed-time linear movement), so positioning matters: line up the drill stab and the dig zone with the biggest clump of enemies to get the full knockback and summon value.

Synergy: Volley + Duration

Cool Mint consumes two synergies — Volley and Duration — and grants none herself, so her synergy bonuses activate through teammates that supply them:

• Volley providers: Cheesecake Cookie, Herb Cookie, Tiger Lily Cookie
• Duration providers: Cheerleader Cookie, Coffee Cookie, Milk Cookie's Crunchy Strong Pediatrician

Cheesecake Cookie is the most efficient Volley source for a Water comp, and Coffee Cookie doubles as a support that keeps energy flowing — a natural pairing if you are building around Cool Mint.

Best teams for Cool Mint Cookie

• Water core: Cool Mint Cookie + Cheesecake Cookie (Volley) + Coffee Cookie (Duration), rounded out with a Water tank or healer for frontline pressure.
• AoE push line: Cool Mint + Tiger Lily Cookie + Herb Cookie gives double Volley coverage, so her dig chains trigger more consistently against grouped enemies.
• F2P option: Cool Mint + Cheerleader Cookie + Coffee Cookie — both are low-rarity Duration sources, letting a free-to-play roster activate her second synergy cheaply.

Because she is a Water Cookie, she deals bonus pressure against Fire enemies in stage and dungeon content, which makes her a strong pick for the new Rune Crystal Dungeon.

How to get her

Cool Mint Cookie is the featured SSR on the pickup banner that opened with the August 13 update. As with other SSR banners, save your Crystals before pulling and decide your pity position first — banners rotate on the game's two-week update cadence.

Is she worth pulling?

Pros

• Unique excavation mechanic with AoE knockback plus summoned skulls for extra damage
• Fast 1.5s basic attack loop between her 8s skill cooldowns
• Water element coverage for Fire-heavy stages and the Rune Crystal Dungeon

Cons

• Needs Volley and Duration teammates to reach full value
• 8s skill cooldown means uptime depends on skill haste and synergy support

Verdict: a solid SSR pickup for Water teams and AoE content. If you already run a stacked SSR attacker, you can wait for the next banner — but her excavation kit is genuinely new, and she is likely to stay relevant in stage pushing for a while. We will fold her into the tier list once the meta settles after the update.

FAQ

Where does Cool Mint Cookie rank on the tier list? Launch-week testing is still settling. Her early verdict is strong for PvE and Crumble Dungeon; we will update the tier list as the meta forms.

What gear and Sugar Runes should I use? Prioritize ATK and Skill Haste. Sugar Runes that boost ATK% or reduce skill cooldown get the most out of her 8s excavation loop.

Is she good in Arena? Positioning-dependent. Her knockback can disrupt enemy frontlines, but she needs teammates that keep her alive long enough to cast.
