Upper Cindermount Spire: how to beat

A guide to the whole place: waves and bosses in order. Numbers come from the game’s data; loot is in the item atlas and on the Upper Cindermount Spire page.

In short

• Dungeon · levels 55–60 · bosses: 6
• Party: 3 heroes — tank, healer, damage dealer.
• Dungeons have no item level advice: gear of your own level is enough (the place is levels 55–60, the boss is level 55).
• Bosses with a whole-party hit: 2 of 6. Every boss has its own page: abilities, turn-by-turn rhythm, roles.

Waves between bosses

• Before each boss there is a wave of 1–3 enemies of one kind from the list below; the wave’s level matches the next boss.
• Taunt holds the whole wave at once — the tank presses it before the first enemy turn. Damage dealers kill one enemy after another: each kill removes its hits.
• A wave only hits the tank: the biggest takes up to 8% of their Health per turn. Healing the tank is enough; shields and big heals are for the bosses.
