Brimstone Dart
The Sepulcher is a post-Moon Lord boss servant enemy that is spawned during the fight with Supreme Calamitas. It spawns twice during the fight: Once when the initial bullet hell ends, and later when Supreme Calamitas reaches 8% health, shortly after the final bullet hell. Ten Brimstone Hearts will spawn along with it, distributed mostly in the upper corners of Supreme Calamitas's arena. These hearts must be destroyed in order to kill the Sepulcher.
The Sepulcher, notably, deals no contact damage, instead firing diagonal bursts of 
Brimstone Darts from its segments in order to damage the player.

Notes[]
- The Sepulcher has 53 segments in total.
- Brimstone Hearts take 2/3 damage from Celestus' phantom blade projectiles.
- During the Boss Rush, Brimstone Hearts will have 10,000 max health regardless of difficulty.
- The Sepulcher can be killed without destroying the Brimstone Hearts, although this takes a very long time, and requires a weapon capable of getting past Sepulcher's 99.9999% damage reduction without its damage getting reduced to 0 due to Calamity's change to damage rounding (meaning 1,000,000 damage in one hit or more), and as such is not recommended. Killing the Sepulcher this way will still allow the player to progress into the fight.
- The most practical weapon for doing so is the Coldheart Icicle, as its 2% HP drain works on Sepulcher's head, and ignores all DR.
- Weapons cannot pierce through its hitbox.
Trivia[]
- The word "sepulcher" refers to a kind of tomb or burial chamber.
- When defeated, several groups of small passive souls will float out of its remains.
- The tooltip of Metastasis heavily implies that the Sepulcher is what The Devourer of Gods could become should it continue to blindly aim for more power.
