Lihzahrd Power Cell

Lihzahrd Power Cells are used at a Lihzahrd Altar located at the end of the Lihzahrd Temple to summon the Golem boss. They are found within Lihzahrd Chests. They also can drop off Lihzahrds, but only at a 1% drop rate. This means that they can be farmed from Lizahrds, but there is a better alternative if you have multiple Temple Keys from killing Plantera; you can simply generate a new world and gather new power cells from that world's Lihzahrd Temple.
