The Plasma Caster is a craftable post-Moon Lord magic gun. When used with the primary fire (left-click), it slowly fires a plasma bolt that does not pierce and create a large explosion on hit. When used with the secondary fire (right-click), the bolts are fired three times faster, deal one third of the damage, cost one third as much mana, and have lower accuracy. Bolts are able to inflict the On Fire! and Cursed Inferno debuffs.

The weapon consumes 0.32 and 0.12 units of charge per use in primary-fire and secondary-fire respectively, and has a maximum charge of 190.

Its best modifier is Mythical.



The Plasma Caster cannot be crafted until the Encrypted Schematic from the Underworld Bio-center Lab is decrypted. If the requirement has not been met, two lines of tooltip are added at the bottom of the item:
You don't have sufficient knowledge to create this yet
