Blood Oath is a passive item.

Effects

  • Stabs Isaac at the beginning of each floor, draining all but half a heart of his red heart containers.
    • Increases damage and speed each time Isaac is stabbed. The stat increases scale with the amount of health lost.
    • Isaac can avoid damage from Blood Oath with invincibility, but he won't gain the damage and speed increase if he does.
    • If Isaac is already at half a red heart, no blood is taken and no stat increase is granted.

Notes

  • It is possible to prevent red hearts from draining while still gaining the stat increases, as long as Isaac's speed is high enough to immediately leave the starting room.
  • This item has no effect on The Lost or ???; they don't take damage and get no stat increases.
  • Being stabbed does not remove Eternal Hearts.
  • If Isaac has Rotten Hearts, each Rotten Heart leads to the loss of half a Soul Heart.
    • If Isaac does not have enough Soul Hearts, he will die.
  • Being stabbed does not affect the chance for Devil/Angel rooms to appear.

Synergies

  • Bloody Lust: Damage taken by Blood Oath at the beginning of the floor triggers the Bloody Lust damage bonus for each half-heart lost. By losing more than 3 Red Hearts, it is possible to gain the max damage bonus of Bloody Lust at the beginning of the floor.
  • BFFS!: Increases the amount of damage Blood Oath gives you.
  • The Habit: Grants 1 charge per half-heart taken by Blood Oath.
  • Menorah: Lights one candle per half-heart taken by Blood Oath.

Interactions

  • Gnawed Leaf: If Blood Oath stabs while Isaac is in statue form, he takes no damage but also receives no damage bonus.

In-game Footage

Trivia

  • This item originated from the Binding of Isaac: Community Remix mod.
  • The appearance of the familiar changes depending on the amount of health it has taken on the current floor: it stays clean if no health was taken and becomes bloodier the more health was taken.
