Bursting Sack is a passive item added in The Binding of Isaac: Afterbirth.

Effect

• Certain spider enemies no longer target or deal contact damage to Isaac, nor actively spawn other enemies. Spiders that are spawned from enemies that are not affected by Bursting Sack will also remain neutral.
  • Affected spider enemies that deal no damage to Isaac whatsoever include: Spider, Big Spider, Swarm Spider, Strider, Rock Spider, Tinted Rock Spider, Level 2 Spider, Trite, Baby Long Legs, Small Baby Long Legs, Crazy Long Legs and Small Crazy Long Legs.
    • Spiders and Big Spiders don't blink red when Isaac has the item.
    • Swarm Spiders don't blink yellow when Isaac has the item.
    • Trites will still uselessly try to target Isaac.
  • Affected enemies that deal no contact damage but can still damage Isaac through other methods include: Ragling, Rag Man's Ragling, Blister, Ticking Spider, Migraine, Wall Creep, Blind Creep, Rage Creep, The Thing, Soy Creep, Tainted Soy Creep and Rag Creep.
    • Except for Ticking Spiders, Migraines and Blind Creeps, all other spiders will still uselessly try to target Isaac for contact damage.
  • Coal Spiders aren't aggressive to Isaac, but will still deal contact damage.
  • Unaffected spider enemies include: Trite, Ragling, Rag Man's Ragling, Blister, Wall Creep, Blind Creep, Rage Creep and The Thing.
  • Twitchy is the only "spider" enemy that is still aggressive towards and will still damage Isaac, as they're classified as a Gaper rather than a spider.

Notes

• If either Jacob or Esau holds Bursting Sack, neither characters will be hurt by the affected spiders.

Trivia

• This item is similar to Skatole, only affecting spiders instead of flies.
• Hence the name, this item's appearance is similar to a bursting Sack.
