Overview
Iron Fortress is one of the themes the game picks when a dungeon is generated. The theme brings the monsters of the rooms and the guardian of the arena. Its signature hazard is lava: lava floors.

Monsters
| Monster | Weight | From rank |
|---|---|---|
| Ash Hound | 3 | any |
| Siege Arbalist | 3 | any |
| Cinder Brute | 2 | D |
| Abyss Knight | 2 | C |
The weight is how often the monster is picked for a room. Its minion (the adds a guardian calls) is Ash Hound.
Guardian
Cinder Colossus - the final fight. Each variant (standard, enraged, summoner) is rolled when the dungeon is generated: guardian variants.
