Black Widow

The Black Widow 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, Black Widows 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 become less visible, in a manner similar to stealth, the farther away they are from the player, reaching minimum visibility at about 18 blocks away. If the player gets bit by them, Black Widows have a chance to inflict the Widow's Kiss debuff, halving their health after the debuff runs out.
