Brimstone Crag

*"The scent of broken promises, pain, and eventual death is heavy in the air..."*

The **Brimstone Crag** is a biome added by the Calamity Mod which spawns upon world creation. It can be found at the left side of The Underworld. It is composed of several large masses of Brimstone Slag half-buried in the ash, with deposits of Charred Ore interspersed within it. Across the crag there are several house-like structures, each containing a locked Shadow Chest with various Underworld items inside. Buried underneath the crags are three of these structures, which are unique in that they contain loot that is normally only obtainable from enemy drops, including the Philosopher's Stone.

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. The Wall of Bronze can also be spawned in the crags by placing a Bloody Vein into the Ancient Console.

In Death Mode, Brimstone geysers will also occasionally erupt from the lava.

## Notes

* Chunks of Brimstone Slag generate in the lowermost Cavern layer above the main Brimstone Crag, extending the biome out of the Underworld to some degree.
* Player-created Brimstone Crag biomes are possible by placing more than 50 Brimstone Slag and/or Charred Ore in an area.
* The three chests buried in the center of the biome are only accessible with the Molten Pickaxe, Rod of Discord, Actuators, or the Onyx Excavator Key.
* 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.
* The Philosopher's Stone can be obtained as soon as Skeletron is defeated, due to the player's access to Actuators and the Shadow Key.
* In Hardmode, it is a great place to farm for Essence of Chaos, as all of the biome's inhabitants can drop it.
* If the Hardmode Underworld's environment proves too inconvenient or treacherous, the blocks from the Brimstone Crag can be moved elsewhere in the world to form an artificial biome that the player has more control over.

## Trivia

* 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, due to her connection to the biome in the lore. A section of Supreme 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.
