Sworn Protector

Sworn Protector is an unlockable passive item.

Effects[]

Spawns an orbital familiar that blocks enemy shots and deals 7 damage per tick or 105 damage per second on contact ( 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 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.
This item belongs to the Seraphim set. Collecting three items from this set will transform Isaac into an angel.
This item belongs to the Conjoined set. Collecting three items from this set will transform Isaac into a three-faced version of himself.

Sworn Protector can be exploited with the help of a Constant Stone Shooter to spawn unlimited eternal hearts.

Extension Cord: Familiar and Isaac are occasionally connected by electricity but it is very hard to notice because of Sworn Protector orbits so close to Isaac.
Friendly Ball / 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.
