Guild Boss Guide

Guild Boss is a daily cooperative event where your entire guild works together to defeat a powerful boss within a 30-minute combat window. Both guild-wide and personal rewards scale with total damage dealt — so every member’s contribution counts.

Note: Point values and reward thresholds may vary by server and are subject to change.

When the attack period opens, guild members can send troops, join rallies, and deal damage to the boss. The combat stage lasts 30 minutes.

  • Guild Rewards are based on total guild damage dealt during the combat period
  • Individual Rewards are based on your personal damage contribution
  • The top damage dealer boosts Guild Rewards by 10× — a significant multiplier worth competing for

Each day you receive Charm Arrows from completing daily tasks. Donate them on the Guild Boss screen to:

  • Boost the guild’s total damage output
  • Earn Guild Points for the donation

Donate your arrows before the attack window closes — unused arrows are wasted outside this context.

Guild Boss runs on your device’s local timezone, so plan to be online when the attack period opens. Missing the window means missing the full reward tier.

  • The combat stage is 30 minutes — be ready before it starts
  • Don’t send rallies to other world map mobs during the Guild Boss attack period; all available queues should go to the boss only

The Auto-Join Rally button only appears during the attack period. Use it to keep your marches hitting the boss even when you’re not actively tapping.

Optimal setup:

  1. Load your strongest troop compositions into auto-rally queues — these will march continuously to the boss
  2. Use your weakest queue to manually start the initial rally, so your best troops join as reinforcements
  3. Once auto-rally is running, check back periodically to confirm queues are still active

This approach maximises march efficiency without requiring constant attention during the 30-minute window.

After the boss dies, open the Rewards tab and check your personal damage tier.

  • If you haven’t reached the highest reward tier, keep attacking — the boss can still be hit after it’s defeated
  • Coordinate with guild members to contest the top damage slot — that 10× guild multiplier is a major boost for everyone’s rewards
  • Save Charm Arrows — don’t spend them on other events when Guild Boss is approaching
  • Communicate attack times in guild chat so members across different timezones can participate
  • Prioritise the boss over other world map activities during the 30-minute window
  • If the guild is close to a damage milestone, call for a push in guild chat before time runs out
