How to Beat Stage 10-30 in CookieRun: Crumble

Clearing stage 10-30 in CookieRun: Crumble requires more than just high-level stats; it demands active control of your team during the boss fight. The most critical strategy for success is manual positioning to avoid high-damage area-of-effect attacks. By timing your skill activations and moving your Cookies out of danger zones, you can mitigate incoming damage and ensure your team survives long enough to secure the victory.

Essential Combat Tactics for the 10-30 Boss

Success at stage 10-30 relies heavily on your ability to react to the boss’s telegraphed attacks. Rather than relying on auto-battle, take manual control to preserve your team's health pool.

Prioritize Movement: When the boss initiates its sweeping or area-based attacks, immediately drag your Cookies away from the red danger indicators.
Cooldown Management: Avoid spamming all your skills at once. Hold back specific defensive or healing abilities until the boss uses its most punishing attacks to ensure your Cookies remain topped off.
Focus Fire: Ensure your damage dealers are targeting the boss consistently while your support Cookies stay positioned at the edge of the screen to minimize the risk of being caught in the boss's primary attack range.

Recommended Team Positioning

Positioning is a primary factor in surviving the encounter without losing key units early.

Role	Strategy
Frontline	Keep them engaged to draw aggro, but move them back if their health drops below 30%.
Healer/Support	Position them away from the boss's direct line of sight to prevent collateral damage.
Damage Dealers	Rotate them in and out of range to maintain uptime while avoiding the boss's special ability animations.

Managing Boss Mechanics

The boss in stage 10-30 features specific patterns that can wipe a team if ignored. Pay close attention to the boss's "Cool" meter or attack charge animations. When you see these cues, stop your DPS rotation briefly to focus entirely on repositioning. If your Cookies are currently locked into an ability animation, you may take unnecessary damage, so timing your skill usage between the boss's attack windows is the most effective way to progress through this stage.
