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 Nightmare Pickaxe, a Deathbringer Pickaxe, or better, Purification Powder. The first Crimson Heart broken also fulfills one of the two criteria for a Goblin Army to attack, which has a 1/15 chance of occurring on each subsequent day (you will also need to have at least one player that has 200 or more health in order for the Army to begin invading).
