Sacks are spider-web variants of normal Boils added to the Wrath of the Lamb DLC. They cannot replace Boils or Guts, but can commonly be found in the Cellar.

Behavior[]

Sacks don't shoot projectiles, instead, they periodically spawn Spiders when fully swollen. Therefore, damaging them will prevent them from spawning Spiders, making them easy to kill.

Champion Behavior[]

In Hard Mode, which was added to the Eternal Edition update, the Eternal Sacks spawn 2 spiders instead of one. They are among the easiest Eternal enemies to defeat, as they still will not attack if they are not at full size.

Notes[]

  • They can be spawned by spider-type bosses, such as the Widow.
