CookieRun: Crumble Guild Raid Guide — Piñata Boss, Rewards & Teams

Guild Raid is the new weekly cooperative mode: how the Piñata boss works, Guild Medal rewards, ranking and the best team comps for max damage.

Guild Raid is the flagship cooperative mode of the August 27 update. Every guild member fights the same raid boss with their own team, and the damage everyone deals is added up into a guild score. Here is how it works and how to squeeze out the most damage.

How Guild Raid works

  • Guild-wide boss fight — each member challenges the raid boss separately with their own 12-Cookie team.
  • Raid groups — five guilds form a raid group and compete against each other through a tier-based ranking system.
  • Weekly seasons — rankings and rewards reset every week, so participation matters every season.
  • Score = damage — the damage you deal is converted into points that add up to your guild's total ranking.

The boss: Extra-Stuffed Piñata

The current raid boss is the Extra-Stuffed Piñata (Korean: 지나치게 무거워진 피냐타) — a giant HP sponge. Because its HP pool is enormous, the fight is a pure damage race: sustain and single-target DPS beat AoE here.

  • Bring your strongest single-target team — Burst and Chain attackers outperform wave-clear units.
  • Tea Knight Cookie is the MVP — his Battlemaster skill grants allies bonus Boss damage in Guild Raid, the only buff of its kind in the game.
  • Brightseeker Cookie pairs well with Tea Knight as a long-range damage dealer that can stay alive through the whole fight.

Rewards: Guild Medals and honor rewards

Participating in Guild Raid earns Guild Medals and honor rewards based on your performance and your guild's final rank. The Guild Medal exchange shop includes exclusive Cookies and Pets that you cannot get from the gacha, so even casual guilds should complete their daily attempts.

Guild Raid checklist

  1. Join or create a guild before the season starts.
  2. Build a single-target damage team — one tank (ideally Tea Knight), one healer, and the rest burst DPS.
  3. Check your synergy setup with the team builder before locking in.
  4. Do not waste attempts: the fight is about total damage, so retry with your best comp even after the boss "dies" for you.
