Siege Mechanics

The Crown Switch System:

  1. The Crown is located in the Dragon Tower (center of castle)
  2. A player must stand on the Crown Switch to claim it
  3. The switch has a progress bar - stay on it to fill the bar
  4. If interrupted (killed/moved), progress resets
  5. The guild controlling the crown when siege ends WINS

Castle Gates

Outer Gate

First barrier, must be destroyed to enter

Inner Gates

Multiple inner gates protect the tower

Dragon Tower

Final destination - Crown location

Guardian Statues

Defenders can activate Guardian Statues that deal damage to attackers. These must be destroyed by attacking guilds or they'll take heavy casualties.

Attack Strategy

Attacking Guild Tactics:

  • Phase 1: Destroy outer gate with full force
  • Phase 2: Split forces - some destroy statues, main force pushes
  • Phase 3: Breach inner gates, clear defenders
  • Phase 4: Secure the crown room
  • Phase 5: Get your designated player on the switch
  • Phase 6: Defend the switch holder until siege ends
Key Tip: Coordinate with allied guilds! Multiple attacking guilds fighting each other is how defenders win. Form alliances before siege day.

Defense Strategy

Defending Guild Tactics:

  • Pre-siege: Repair all gates to full HP
  • Activate: Turn on all Guardian Statues
  • Gate Defense: Station players at each gate chokepoint
  • Crown Guard: Keep your strongest players at the crown
  • Counter-attack: Push out when attackers are weakened
  • Switch Control: ALWAYS have someone on the switch
