Guild Conquest is the cooperative mode CookieRun: Crumble added on August 27, and it works differently from every other fight in the game. Your damage against the Extra-Stuffed Piñata is converted into points, those points stack with your Guildmates’, and the total gets ranked weekly inside a Group of five Guilds and against every other Guild. Rewards come back as Guild Medals, honor rewards, and Diamonds. One good run can pull a whole Guild up a bracket.
Quick answer: Build a single-target team around Scorpion with DEF Down, CRIT buffs, and Lift Resistance, reclaim EXP from unused Cookies to level that team as high as it will go, then run the Piñata three to five times and lock in your best score on the final day of the season.
How Guild Conquest scoring works
The Piñata is a Dark boss, so Light attackers hit harder against it. That is the only fixed advantage in the fight. Everything else is variance. Targeting, crit rolls, debuff application, and skill cast timing all shift between attempts, which is why the same account with the same Runes can post wildly different numbers.
The swing is large enough that a single run tells you almost nothing. Four attempts with only minor lineup changes can look like this:
| Lineup used | Score |
|---|---|
| Full team, first attempt | 1,331,406,585 |
| Same team, repeat run | 1,729,497,741 |
| Nameless Cake Hound instead of Tea Knight | 1,503,723,252 |
| Strawberry Crepe instead of Melon Soda | 1,606,809,992 |
The second run beat the first by roughly 400 million damage with nothing changed. Entries are unlimited, so treat every attempt as a roll and keep the best result rather than averaging your luck.
Every Cookie’s job against the Extra-Stuffed Piñata
Do not stuff the formation with Light Cookies just because the boss is Dark. All twelve slots need a job, and if one of those jobs disappears, another damage dealer rarely makes up the loss. Check roles before you check Power totals.
| Cookie | Job in the fight |
|---|---|
| Brightseeker Cookie | TSSR Light Ranged damage; Satellite Shock hits the Dark boss hardest |
| Tea Knight Cookie | Boss DMG Up for the whole team |
| Scorpion Cookie | Main damage over time; the centre of the plan |
| Rye Cookie | Burst damage on a short cooldown |
| Melon Soda Cookie | Second single-target damage cycle |
| Wind Archer or Milky Way Cookie | Extra focused damage slot before you own Brightseeker |
| Macaron Cookie | CRIT Chance |
| Skating Queen Cookie | CRIT DMG |
| Pomegranate Cookie | Skill Amp Up on eligible skills |
| Tiger Lily Cookie | Volley Synergy provider |
| Dark Choco Cookie | DEF Down on the boss |
| Pinot Noir Cookie | Lift Resistance and Rapid Fire Synergy |
| Nameless Cake Hound | Damage reduction so nobody dies mid-cast |
| Milk Cookie’s Crunchy Strong Pediatrician | Healing plus stacking ATK |
Scorpion is the one to invest in first. Five stars makes her damage over time land far more reliably, and reliability is worth more here than a single lucky spike. Volley Synergy is worth keeping active as well; Tiger Lily is the usual provider, and Herb Cookie or Cheesecake Cookie can fill in if she is missing.
Two more details matter. CRIT Chance does not go dead at 100% here, since chance above 100% can roll a double crit and above 200% a triple crit, which is why Macaron and Skating Queen stay paired. And Pinot Noir’s Healing Received Down does nothing to this boss, so she is in the lineup purely for Lift Resistance and her synergy.
Save Guild Medals for Tea Knight Cookie
Tea Knight Cookie is an SSR Light Tank you cannot pull from any banner. He exists only in the Guild Medal Exchange, and his Boss DMG buff applies to your entire formation, which makes him the single most valuable purchase in the store for this mode. Skip the cheap filler and bank medals until you can max him out. More Boss DMG means more damage, which means more medals, which is how the mode snowballs.
When Tea Knight is ready, the swap order matters. Brightseeker replaces Wind Archer or Milky Way. Tea Knight replaces whichever of Rye or Melon Soda is weaker on your account. Dark Choco stays, because dropping DEF Down cancels out most of the gain you were expecting from the new Cookie. Devil Cookie can cover DEF Down on some rosters, but Dark Choco is the safer default.
If you do not have the premium units yet, the substitutes hold up. Nameless Cake Hound covers for Tea Knight, and Popcorn Cookie or any strong damage dealer covers for Brightseeker. Strawberry Crepe and Vampire are both usable in the flexible damage slots.
Pet loadout for the Piñata fight
Run Holy Baby Drop, Hot Doggie, and Panda Dumpling together. Holy Baby Drop raises allied ATK, Hot Doggie supplies Skill Amp Up, and Panda Dumpling completes the anti-lift package alongside Pinot Noir. Getting lifted costs you casts, and lost casts cost far more damage than a flashier offensive Pet returns.
Octo-Wasabi is the alternative worth testing if your damage dealers are built around Duration Synergy. Chargemellow, the SSR Pet added alongside the mode, grants Rapid Fire Synergy if your lineup leans that way instead.
Sugar Rune priorities by role
Damage dealers all start from the same three stats, and supports need slightly different handling depending on what they are checking.
| Cookie | Rune priority |
|---|---|
| Damage dealers (Rye, Melon Soda, Wind Archer, Milky Way, Brightseeker) | ATK Amp, Skill Amp, Skill Haste |
| Scorpion | Skill Haste, Skill Amp, ATK Amp, plus Focus when the DoT misses |
| Macaron, Pomegranate, Skating Queen, Tiger Lily, Milk Cookie’s Crunchy Strong Pediatrician | Skill Haste and Skill Amp |
| Pinot Noir | Focus, Skill Haste, ATK Amp |
| Dark Choco | Focus and Skill Haste, plus defense if he dies early |
| Nameless Cake Hound | Skill Haste and HP Amp |
Note: Skill Amp no longer strengthens Dark Choco’s DEF Down, and it does nothing for Pinot Noir’s Healing Received Down. Do not burn rerolls chasing either. Fix Scorpion’s page first, then whichever support keeps dying, then the better of Rye and Melon Soda. Rebuilding twelve Rune pages in one sitting is a waste of materials.
Reclaim EXP from unused Cookies before your run
Levels feed directly into damage, and most accounts have EXP sitting in Cookies that will never see the Piñata. The Reset Level feature returns that EXP so you can push your Conquest twelve as high as your roster allows.
You will know it worked when the levels on your twelve Conquest Cookies climb and your team Power figure rises before you queue into the boss.
Time your scoring run for the last day of the season
Your team keeps getting stronger across a season as Runes, levels, and medal purchases accumulate. Since entries are unlimited, do your experimenting early and save the run that counts for the final day, when the lineup is at its peak.
When you do test, change one thing at a time. Swap Wind Archer for Milky Way, run three times, compare. Then add Brightseeker and run again. Wind Archer generally comes out ahead when both are equally invested, but a five-star Milky Way with finished Runes will beat an underbuilt TSSR, so let your own scores decide rather than the rarity label.
Why your score stays low
If the number swings between runs but every Cookie survives, the lineup is fine and you simply need more attempts. If the same Cookie dies early every single time, fix that Rune page or add defense before you touch the damage core.
The other common causes are structural. A formation with no DEF Down, no Lift Resistance, or no CRIT support is leaking damage no matter how much Power it shows. Scorpion below five stars will miss her damage over time often enough to make results unreadable. And dropping Dark Choco to make room for a shiny new Cookie is the single most expensive mistake in the mode.
Guild Conquest rewards patience more than perfection. Get the twelve jobs covered, keep the three Pets together, bank your medals for Tea Knight, and then let the retries do the rest.
