The Fortress of Souls raid boss and his drops.
The Fortress of Souls is a boss raid against Soltar, fought across three phases. Each phase is its own fight, and the further you push Soltar's HP down, the better the rewards.
Rewards are threshold-based: you earn the tier for the lowest HP bracket you reach (getting him to 35% pays the 40% tier), not a running total. Every attempt drops Soulbound crystals (Crystal Powder, Crystal Shard, and Crystal) plus Gold and Honor, and the amounts climb with each phase.
Those crystals, together with Iron, are spent at the Smithy to forge and enhance Soulbound Weapons. The raid is opened from the Fortress of Souls building.
Time limit per attempt: 15:00
If the timer runs out, Soltar uses Time Over: 2000% ATK true damage, 30 hits over 2s - effectively an unsurvivable wipe (true damage ignores DEF and RES). He also ramps as the fight drags: +25% ATK per countdown step (4 steps, +100% total), plus a permanent +10% ATK every time he casts a special skill. Treat the fight as a DPS race - kill him before he gets there. (Time limit per attempt: 15:00)
Reward quantities increase as you push Soltar's HP lower.

Ranges run from the easiest HP tier to a full kill. You receive the single tier for the lowest HP you reach, not the sum of every tier.
