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.
 * 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 will 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.

Interactions

 * 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.
 * / : 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.
