Sunfire Castle

The castle battle that decides who rules the state. It’s fought during the SvS battle phase.

TL;DR Hold the Castle for 2.5 hours straight or have the longest total hold. Contest the four turrets, because enemy-held turrets grind down whoever holds the Castle.

2.5 h continuous hold

State President

Rules

  • Fought during the SvS battle phase, 12:00–17:00 UTC, in the state that lost the prep phase.
  • Hold the Castle for 2.5 consecutive hours to win outright. If an enemy captures it, even briefly, the timer resets.
  • If nobody reaches 2.5 hours, the longest total occupation wins.
  • Only one march per player can be in or attacking the Castle. Entering the Alert Zone drops your shield.

A patch in October 2025 shortened these from 6 hours / 3 hours, so older guides are out of date.

Turrets & scoring

  • There are four turrets around the Castle.
  • A turret held by the other side attacks whoever holds the Castle, and it hits harder the longer it’s held.
  • Holding the Castle or a turret earns SvS points: 1 point per 1,000 Power every 60 seconds.
  • Kills and losses only score against players within ±3 Furnace levels, and higher-tier troop kills are worth more.

The presidency

  • The winning alliance’s R5 appoints the State President.
  • If they don’t choose within the time limit, the R5 becomes President automatically.
  • The President’s skills (such as construction and training buffs) matter for the next SvS prep days.

Strategy

  • Assign roles: fighters, rally leaders, reinforcers and support.
  • Holders: keep reinforcements constant and retake turrets so they stop chipping your garrison.
  • Attackers: chain rallies from strong leaders to break the hold and reset the 2.5-hour timer.
  • Weaker players should shield before the Castle fight. The event doesn’t end when the Castle does.
