Binding of Isaac: Rebirth Wiki

Added in Afterbirth

Sworn Protector is an unlockable passive item added in The Binding of Isaac: Afterbirth.


  • Spawns an orbital familiar that blocks enemy shots and deals 7 damage per tick or 105 damage per second on contact (Added in Repentance 56 damage per second).
    • It also attracts enemy shots to itself, making them more likely to be blocked. A shot actively being attracted can no longer damage Isaac and is essentially nullified, but if it slips outside the Protector's range, it can again deal damage.
  • Sworn Protector has a chance to drop an Eternal Heart Eternal Heart upon blocking 10 shots in one room.
    • This can only happen once per room, but leaving and re-entering a room will allow another eternal heart to be dropped.
  • Removed in Repentance This item belongs to the Seraphim set. Collecting three items from this set will transform Isaac into an angel.
  • Added in Repentance This item belongs to the Conjoined set. Collecting three items from this set will transform Isaac into a three-faced version of himself.



  • Added in Afterbirth †Extension Cord Extension Cord: Familiar and Isaac are occasionally connected by electricity, but it is very hard to notice because Sworn Protector orbits so close to Isaac.
  • Friendly Ball Friendly Ball / Added in Afterbirth †Poke Go Poke Go: Catching an enemy that shoots bullets allows Eternal Hearts to be farmed since the enemy will fire at Isaac if no other enemies are in the room.
