Heart Statue

The Heart Statue drops a Heart when activated using Wire. It has a cooldown time of ten seconds. It can be found in caverns underground and in the Dungeon.

The spawning of Hearts can be abused to create a farm for infinite health. However, due to the ten second spawn timer, a large number of heart statues are necessary for this to be effective. The statue also will not spawn a heart if there are 10 or more hearts anywhere in the world, 6 or more hearts within 800 pixels (100 blocks), or 3 or more hearts within 300 pixels (36 blocks). A partial work-around to this limitation is to place the statues high on narrow ledges, allowing some or all of the hearts to drop. (But they need to be at over 36 blocks above the place where the hearts will land.)

You can mitigate the effects of the 10 second timer by connecting wires, repeaters, and switches to activate them to up to 6 locations on the statue, (which is 3 blocks tall,) so long as no wires of the same color touch one another to short a circuit. (This requires multiple colors of wire.) A single statue can then produce 6 hearts per 10-second cooldown, provided the player is collecting them (picture needed).

Since setting up wires, repeaters, switches, and statues is fairly time-consuming, these statues are most useful, along with the Star Statue, in setting up either a boss-fighting arena, or a monster-farming platform. (Such as for defense against a Goblin Army, or possibly for fighting in a Solar Eclipse.) Using heart statues in conjunction with high armor ratings and accessories to boost regeneration or lengthen damage-invincibility can make a player character significantly harder, or even outright impossible, for a boss to kill.
