Tarantula

The Tarantula is a Hardmode enemy that can be found in and around Spider Caves after the Borean Strider has been defeated. Like other spider-like enemies, Tarantulas 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. When damaged, Tarantulas release hairs all around them that inflict the Venom debuff on hit players.
