Community Remix Remixed/Blood Oath

Blood Oath is a passive item from Community Remix Remixed.

Effects

 * The first enemy Isaac hits in the room will be linked in a "Blood Oath." They are given a status icon to represent this.
 * A linked enemy will give Isaac speed and damage buffs the closer their HP is to 0. When they hit 0, the buffs end.
 * At critically low health, a linked enemy will begin spawning red creep and firing short-range red tears in random directions.
 * Bosses are ignored by Blood Oath.

Trivia

 * Blood Oath was an item in the original Community Remix, with a completely different effect. In the original, Blood Oath would grant a +1.8 damage up, with a -0.17 damage penalty for every Red Heart that Isaac currently has.
 * Soul Hearts were not included in the damage penalty, causing a lot of players to believe that the original effect is extremely broken.
