#569Blood Oath"Bleed me dry"Familiar
Spawns a familiar that follows Isaac and stabs him at the beginning of the each floor if he has more than half a red heart.

The familiar will drain as much red hearts as possible without killing Isaac, ultimately leaving him at half a red heart, or no red hearts at all if he has other types of hearts that will keep him alive.

When stabbed, Isaac gains increased stats for the rest of the floor: +0.15 × HeartsLost ^ 2 worth of damage, and +0.1 × HeartsLost worth of speed.

Even though a single stab animation, every bit of damage taken is treated separately per half a heart lost, which can lead to synergies with some items.
