Rood

Rood is a passive item added in Pack 1.

Effects

 * Reverses devil and angel roles:
 * Devil rooms offer free items, however, Isaac only can take one of them. On the other hand, angel room items are charged but Isaac can purchase multiple ones.
 * Angel room items have to be bought with "angel pacts". Doing an angel pack forces angel rooms to appear the entire run and nullifies the chance of finding devil rooms.
 * Pacts are also reversed, starting with three soul hearts (if Isaac has at least three soul hearts), and then two red hearts.
 * Angel statues are invulnerable and no longer spawn angels. Now it's necessary to bomb devil statues which spawn dark angels. Dark angels drop key pieces upon defeat and can only be fought once per floor.
 * Isaac causes all enemies to temporary bleed upon taking damage.

Synergies

 * Duality: No longer disables devil rooms after doing angel pacts.
 * Dull Razor: Applies bleeding effect without taking damage.
 * Judas's Tongue: Angel items only cost one red heart instead of two.
 * Filigree Feathers: Keys spawned from dark angels are replaced with devil items.

Trivia

 * Rood is also available as a stand-alone mod in the Steam Workshop.
