Brimstone Crag

"Oft called the First City, its tumultuous history stretches back to the Draconic Era."

The Brimstone Crag biome, as viewed on the map in a large world.

The Brimstone Crag is a biome added by the Calamity Mod which spawns upon world creation. It can be found in The Underworld on the same side of the world as the Dungeon; it is underneath the Abyss on the far edge of the map.

Similar to the Underworld, it has a ceiling layer and a large lower terrain. Its ceiling is covered with stalactites and Brimstone Slag spanning across the entire biome. The lower terrain is mostly composed of an extremely dense layer of Brimstone Slag, with several large parabolic areas of Scorched Remains, and patches of lava and Infernal Suevite. The surface of Brimstone Slags are scattered with Spine Trees, while the surface of Scorched Remains are covered in Cinder Blossom Grass and Lava Lilies.

The Brimstone Crag also contains a few ruined structures across the biome, which are primarily built out of Brimstone Slabs and Ashen furniture. The middle of the biome contains a large broken bridge over a shallower lava lake, which contains an Ashen Chest in one of the exposed broken pillars.

Contacting lava in the Brimstone Crag causes the player to be inflicted with the Searing Lava debuff.

The Brimstone Elemental boss can be summoned here by using a Charred Idol.

Notes

Brimstone Crag Bestiary Background.

• Player-created Brimstone Crag biomes are possible by placing more than 100 Brimstone Slag and/or Infernal Suevite while in The Underworld.
• While in the biome, Lava gains a stronger red color.

Tips

• It is risky to visit this biome in Pre-Hardmode, as the enemies in it are quite powerful and killing them will garner very few rewards apart from money and the Slurper Pole.
• In Hardmode, it is a great place to farm for Essence of Havoc, as all of the biome's inhabitants can drop it.

Trivia

• In the Lore, the Brimstone Crags are the ruins of the city Azafure, having been mostly destroyed during Supreme Witch, Calamitas' fight with the Brimstone Elemental.
• The Brimstone Crag's theme is The Step Below Hell, which was composed by the artist DM DOKURO.
  • The main musical motifs are the themes of Brimstone Elemental, due to being the biome's boss, and Calamitas Clone, due to her connection to the biome in the lore. A section of Supreme Witch, Calamitas' theme notably uses the melody from The Step Below Hell.
  • If the Calamity Music add-on mod is disabled, Eerie will play instead.
• It was previously known as the "Profaned Crags". This was changed to prevent any kind of unwanted connections with Providence, the Profaned Goddess. Before that, it was known as the "Calamity biome".
• In an earlier version of the mod, the Brimstone Crag was located on the far left edge of the Underworld, and featured several tall spires and a large eye-like formation underneath. This was changed due to taking a significant amount of time to generate, along with being inconvenient for fighting the Brimstone Elemental.
