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 0.5% drop rate (1 in 200 chance). This means that they can be farmed from Lihzahrds, but there is a better alternative if you have an extra Temple Key from killing Plantera, a Picksaw from killing Golem, or a Rod of Discord; you can simply generate a new world and gather new power cells from that world's Lihzahrd Temple.
