Room milestones
Dungeon Rooms, Loot and Map XP
Known room milestones and a progression table that leaves unverified enemy, drop and Map XP fields clearly marked.
Quick answer
Use the latest unlocked room as your route anchor. Rusty Mines, Crystal Hollows, Buried Catacombs, Swamped Crypt, Altar of Ashes, Obsidian Caverns and Sanctum of the Dead King are achievement-backed room milestones.
Current recommendation: When a room blocks you, fix one axis at a time: party if you need survival or role coverage, weapons if clear speed or range is the issue, skill tree if a permanent purchase is available.
What to do next
- 1
Check the room already unlocked before changing a party or weapon.
- 2
Use named room milestones to choose the next dungeon target.
- 3
Treat enemy lists, unique drops and Map XP as version-specific unless confirmed in-game.
- 4
Once a new room unlocks, replay the previous room once to compare risk and reward.
