Crimson Heart

Crimson Hearts are floating, pulsing red hearts found deep in the branches of the Crimson. A world with Crimson features several Crimson Hearts, and destroying some of them is often a crucial step in game advancement. This can be done using any Hammer, or Bombs/Dynamite. Crimson Hearts release a fair amount of their own flickering light, similar to Demon Altars, which helps players spot them underground.

Crimson Hearts are usually located at the ends of the branches that split from the main circular room of a Crimson area, kept inside small rooms of Crimstone Blocks. In order to reach them the player may use explosives, a Deathbringer Pickaxe (or better), or Purification Powder]].

Crimson Hearts are the Crimson-equivalent of the Corruption's Shadow Orbs. Like Shadow Orbs, the third one destroyed will summon a boss, the Brain of Cthulhu.
