Lihzahrd Altar

The Lihzahrd Altar is found naturally placed in the final chamber of the Jungle Temple, and is used with a Lihzahrd Power Cell to summon the Golem boss. Each summoning consumes one Power Cell from the player's inventory.

Like Lihzahrd Bricks, the Altar can only be removed with a Picksaw (or a Laser Drill in PC), which is dropped randomly by Golem. Once picked up, the Altar can be placed anywhere and used to summon the Golem in any area, as long as Plantera has been defeated in the current world.
