Lamia

Lamia is a Hardmode enemy that can only be found in the Underground Desert biome. When found in regular Underground Deserts, it has pale blonde hair and has a chance to drop the Sun Mask. Corruption/Crimson Underground Deserts will spawn an alternate variant having much darker hair than its regular counterpart. The "corrupted" version has a chance to drop the Moon Mask. Both variants have a rare chance to drop a piece of the Lamia clothes. Unlike other Underground Desert enemies, the Lamia doesn't have a Hallowed counterpart.
