Golem

Info
The Golem consists of it's body, head and his two fists. The body can only be damaged after the head has been killed. You can fight Golem only after you defeat Plantera and get the Temple Key. The Temple Key is a guaranteed drop from Plantera. To summon the golem, you need a Lihzahrd Power Cell and a Lihzahrd Altar, both can be found in the Lihzahrd Temple.

Summoning this boss will consume 1 Power Cell, but the altar will remain where ever you place it.
