The Sunfire Castle battle is the climax of State vs State — the contested centrepiece that decides which state governs. This is the deep-dive on the castle fight specifically: the exact win condition, the timing math that creates a hard deadline, turret control, and how to attack and defend. For the full SvS event (matchmaking, prep phase, field triage, rewards) start with the SvS guide; this page assumes you're here to win the castle.

Note on numbers: Schedule and hold-time values below reflect the current canonical event design as documented in our SvS guide. Buff and reward amounts are version-dependent and change with balance updates — those are flagged for in-game verification.

Quick Answer (Read This First)

The Sunfire Castle battle is hosted in the defender's state, starts at 12:00 UTC, and lasts up to 5 hours. You win by holding the castle for 2.5 consecutive hours. If no alliance manages a clean 2.5-hour consecutive hold, the alliance with the longest cumulative hold time wins instead. That single rule drives everything: because 2.5 hours is needed, 14:30 UTC is the last moment a winning consecutive hold can begin. Before 14:30, defenders win by breaking enemy holds even briefly (a recapture resets the enemy's consecutive timer); after 14:30, the contest becomes pure cumulative-time arithmetic.

The Win Condition (Read This Twice)

There are two ways the castle is decided, and they apply in sequence:

Clean win — 2.5 consecutive hours. The first alliance to hold the castle for two and a half uninterrupted hours wins outright. A single recapture by the enemy resets that consecutive timer to zero.
Tiebreaker — longest cumulative hold. If nobody achieves a clean consecutive hold by the time the 5-hour window closes (17:00 UTC), the alliance that spent the most total time holding the castle wins.

This is completely different from "hold it at the final whistle." Holding the castle at 16:59 means nothing on its own — what matters is consecutive hold time, then total hold time.

The Timing Math: The 14:30 UTC Deadline

The 5-hour window (12:00–17:00 UTC) plus the 2.5-hour consecutive requirement splits the battle into two strategically opposite zones:

Zone	Time (UTC)	What wins
Clean-win zone	12:00 – 14:30	A 2.5-hour consecutive hold is still possible. Recaptures are devastating because they reset the enemy's consecutive timer.
Tiebreaker zone	14:30 – 17:00	No clean consecutive hold can finish in time. Only total hold time matters; brief recaptures lose value.

14:30 UTC is the hinge. After it, a fresh 2.5-hour hold can no longer fit inside the remaining window, so the battle becomes a cumulative-time race.

Defender priority before 14:30

Reset the enemy's consecutive timer at least once before 14:30. Even a momentary recapture forces the attacker to start their 2.5 hours over — and after 14:30, if neither side has a clean hold, you're into a cumulative count where every minute held matters equally.

Both sides after 14:30

Stop chasing brief flips and maximise total time on the castle. Sustained holding beats repeated short captures once the clean-win path is closed.

Turret Control

Turrets around the castle are a real, exploitable layer. The key fact: an alliance that controls both the castle and the surrounding turrets is reportedly not fired on by those turrets. Consolidating turret control before committing to a long hold means your held castle isn't being chipped by its own defenses, and it punishes attackers who haven't taken the turrets.

For the holding alliance: take the turrets and the castle so the turrets stop damaging your garrison, making a 2.5-hour hold far more survivable.
For attackers: contesting turret control first softens the defender's position before you commit to the castle itself.

Attacking the Castle

Commit to extended holds in the clean-win zone (before 14:30). Accept attrition — a 2.5-hour clean hold wins outright, so it's worth burning troops for.
Coordinate reinforcement waves. Castle holders benefit most from steady, coordinated reinforcement rather than one alliance trying to solo-hold. Stagger waves so the garrison never empties.
Use cross-state teleport. Teleportation ignores alliance territory borders during the Battle Phase — you can land directly near the castle inside enemy territory. (Note: alliance buildings can't be attacked during the Battle Phase, so the castle and field are the fight.)
Take the turrets too, so once you hold the castle they're not firing on you.

Defending the Castle

Before 14:30, break holds aggressively. You don't need to keep the castle in the clean-win zone — you need to deny the enemy a clean 2.5-hour hold. One well-timed recapture resets their timer.
After 14:30, hold for total time. Switch from disruption to sustained occupation; cumulative time is now the metric.
Lead with survivable garrisons. Infantry-forward defensive formations and strong garrison heroes outlast attacker waves.
Rotate reinforcements and use field triage afterward to recover field-killed troops.

Hero & Formation Notes

This is a survivability-and-pressure fight, so bring your best:

Holders / defenders: Infantry-led formations (see the troop formation guide) to absorb and outlast.
Attackers: your strongest rally captains with your best hero gear and chief gear — this is the fight that investment exists for.

Why It Matters: The Outcome

The castle result combines with the Preparation Phase result to decide governance. If the same state wins both the Preparation Phase and the castle, that state's winning alliance leader appoints a Supreme President governing both states for a two-week term; a split result leaves each state with its own President.

This is the key point most guides get wrong: holding the castle does not grant an automatic state-wide buff. The prize is governance — the winning alliance earns the right to appoint Ministry and President seats (and can restrict those seats to its own state), and those appointed positions are where lasting state-level buffs come from. (Separately, the Preparation Phase winner — not the castle winner — gets a Healing Speed and Enlistment Office Capacity buff during the Battle Phase itself.) On top of governance, the castle pays out the event's best loot: Sunfire Tokens, gems, Hero Shards, Fire Crystals and city skins (personal rewards) plus speedups, resources and Mythic Manuals (alliance rewards). The castle is therefore half of the entire SvS outcome — see the SvS guide for the full outcome matrix.

Decision Rules (Sunfire Castle)

IF it's before 14:30 UTC and you're defending, THEN prioritise breaking the enemy's hold to reset their consecutive timer.
IF it's before 14:30 and you're attacking, THEN commit to a full 2.5-hour hold and accept the attrition.
IF it's after 14:30, THEN both sides maximise total hold time; ignore brief flips.
IF you hold the castle, THEN take the surrounding turrets too so they stop firing on you.
IF you're holding, THEN coordinate reinforcement waves rather than solo-holding.

FAQ

Q: How do you win the Sunfire Castle battle? A: Hold the castle for 2.5 consecutive hours for an outright win. If nobody manages that within the 5-hour window, the alliance with the longest cumulative hold time wins.

Q: When does the Sunfire Castle battle start and how long is it? A: It's hosted in the defender's state, starts at 12:00 UTC, and runs up to 5 hours (to 17:00 UTC).

Q: Why is 14:30 UTC important? A: It's the latest a winning 2.5-hour consecutive hold can begin. Before 14:30, recaptures win games by resetting the enemy's timer; after 14:30, only total hold time matters.

Q: Do the turrets attack me if I hold the castle? A: An alliance controlling both the castle and the surrounding turrets reportedly isn't fired on by those turrets — so take the turrets too before settling in for a long hold.

Key Takeaways

2.5 consecutive hours wins outright; otherwise longest cumulative hold wins.
14:30 UTC is the clean-win deadline — strategy flips around it.
Before 14:30, defenders break holds; after 14:30, both sides maximise total time.
Control the turrets so they don't fire on your held castle.
The castle is half the SvS outcome — coordinate reinforcement waves and bring your best gear.
