Demon Heart

Demon Hearts are floating, pulsing red hearts found deep in the branches of the Crimson. Each generated World has several Demon Hearts, and destroying at least some of these will usually be a crucial step in game advancement. This can be done using any Hammer, or Bombs/Dynamite. Demon Hearts release a fair amount of their own flickering light, similar to Demon Altars, which helps players spot them underground.

Demon Hearts are usually located at the ends of the branches that split from the main circular room, separated from the main branch's cavity by some amount of solid Crimstone, and are also surrounded by Crimstone on all sides.

Demon Hearts are a replacement for Shadow Orbs in worlds with Crimson instead of Corruption.

Consequences of destruction

 * Each Heart drops items when destroyed.
 * The first Demon Heart destroyed in a world always drops The Undertaker, along with some Musket Balls.
 * The third Demon Heart destroyed summons the Brain of Cthulhu, which spawns immediately and attacks the player. Brain of Cthulhu is re-summoned with every third Heart destroyed.
