Heart Lanterns

Info
A Heart lantern is a helpful buff-providing lantern item that hangs on the underside of the blocks. It can be crafted with a life crystal, and 4 chains. It is recommended you use the life crystal to increase your health to the highest possible Pre Hardmode level before crafting a Heart Lantern.

Before the mobile 1.4.0.1, you could find Heart Lanterns in the removed Heart Shrine Biome. This Biome appeared underground, and had an ice chest containing multiple health increasing items inside such as Heartreach and Lifeforce potions also with Heart Lanterns. There were also two life crystals next to the chest.

Heart Lanterns are useful for many boss battles, as when placed they emit the Heart Lamp buff, which increases your life regeneration when you are in its vicinity. Be sure to place them with campfires, as their two buffs stack and create an even bigger life regeneration buff. Bathing in honey will even further stack all three into a huge life regeneration advantage over bosses and enemies.
