Cookie Run: Crumble — Guild Conquest Guide

Guild Conquest is the shared raid-boss mode added on August 27, 2026. Every member of your guild fights the same boss with their own team, the scores add up into one guild total, and five guilds sit together in a Raid Group competing on that total. It is the first mode in Crumble where your guild membership changes what you can obtain.

How the scoring actually works

The part that catches people out: you are not trying to kill the boss. Runs are scored on cumulative damage across the season, so a guild of twelve players who each clear a respectable attempt beats a guild with one exceptional player and eleven who never entered. Three consequences follow:

  • Entering at all matters more than entering perfectly. A mediocre logged attempt scores; a skipped day scores zero.
  • Consistency beats a single peak. Because the total is cumulative over the week, a team you can pilot every day is worth more than a fragile setup you only get right occasionally.
  • Your ranking has two layers. Your Raid Group is five guilds; the tier ranking compares you against guilds outside it as well.

What to bring

Devsisters published the mode’s structure but not its numbers — no HP values, no damage thresholds, no reward quantities. So take the following as the shape of the problem rather than a solved build:

  • Boss damage effects are worth more here than raw stats. This is the whole reason Tea Knight Cookie exists: an SSR Light Tank whose value is a Boss DMG buff for allies in this mode specifically. He is a specialist, not a general-purpose upgrade.
  • Sustained damage beats burst. A cumulative-damage score rewards a team that keeps attacking for the full attempt over one that front-loads and then dies.
  • Test in the mode, not next to it. A Cookie that improves your Story clear speed can be worse here, because the target profile is one large enemy rather than a swarm.

The Guild Medal store is the actual reward

Clearing contributes Guild Medals and Honor Rewards, and the Guild Medal Exchange Store sells Cookies and Pets that are not obtainable anywhere else. Tea Knight Cookie is exchange-exclusive — you cannot pull him. That makes guild participation a gating mechanism for roster completeness, not just a source of extra currency.

What is not confirmed

Reward quantities, medal costs, boss HP by tier, season length and reset time were not in the press release or the English notice. Any site printing those numbers today either captured them from a live client — in which case they should say so — or made them up. We will add them when there is something to cite.

Where this sits

Guild Conquest is one part of the wider guild system. The other two Cookies it arrived with are Pinot Noir and Tea Knight; for the rest of the August 27 patch, see the update page.

FAQ

What is Guild Conquest in Cookie Run: Crumble?

A cooperative boss mode added in the August 27, 2026 update. Every member of your guild fights the same raid boss with their own team, and the scores combine into one guild total. Five guilds are placed together in a Raid Group, and a separate tier ranking compares guilds beyond that group.

Who is the Guild Conquest boss?

The English notice calls it the Overly Heavy Pinata. Devsisters' Japanese press release renders the same boss as Over-Sized Pinata. It is a weekly seasonal fight rather than a one-off event.

What do you get from Guild Conquest?

Guild Medals and Honor Rewards, with the Guild Medal Exchange Store carrying Cookies and Pets you cannot get elsewhere - Tea Knight Cookie is exchange-exclusive. Devsisters did not publish the reward amounts, so this page does not list any.
