Brown Recluse

The Brown Recluse is a rare Hardmode enemy that can be found in and around Spider Caves after the Borean Strider has been defeated. Like other spider-like enemies, Brown Recluses are capable of climbing background walls as well as through platforms, but revert to acting like a fighter mob when there is no background wall. They also periodically spawn Recluse Babies that can inflict the Venom debuff on hit. In Expert Mode, Brown Recluses also gain a special spit attack which they use while walking on the walls. It inflicts a long lasting Venom debuff.

Killing a Brown Recluse will complete the "Not So Itsy Bitsy" contract, unlocking the Drider's Grace in the Tracker's shop.
