Community Remix Remixed/Hearts

Community Remix Remixed adds 9 new types of hearts, all of which are variations on existing hearts.

Half Black Heart

 * Grants half of a Black Heart on pickup.

Full Eternal Heart

 * Grants one Heart Container on pickup.

Full Bone Heart

 * Grants one Bone Heart filled with a Red Heart on pickup.

Blended Heart (Black/Red)

 * Behave identically to normal Blended Hearts, only with a Black Heart instead. If Isaac has one or more empty Heart Container, it acts as a Red Heart. If Isaac only has one half red heart missing, it will fill the Heart Container and add one half of a Black Heart. At full health, this acts as one Black Heart.

Blended Heart (Eternal/Soul)

 * On pickup, Eternal/Soul Blended Hearts will give Isaac one Soul Heart and one Eternal Heart.

Blended Heart (Red/Eternal)

 * On pickup, Red/Eternal Hearts fill one Heart Container and give Isaac an Eternal Heart. At full health, this acts as one Eternal Heart.

Blended Heart (Soul/Black)

 * If Isaac has an even amount of Soul Hearts with no half Soul Hearts, this acts as one Soul Heart. If Isaac has half a Soul Heart, this will fill the half Soul Heart and add one half Black Heart.

Double Soul Heart

 * Grants two Soul Hearts on pickup.

Double Black Heart

 * Grants two Black Hearts on pickup.

Double Eternal Heart

 * Grants two Heart Containers on pickup.

Trivia

 * Aside from the Eternal/Soul Heart, all of these heart types are new to Community Remix Remixed.
 * The original Community Remix added Half Soul Hearts, Red/Soul Hearts, Double Red Hearts, and Eternal/Soul Hearts. Other than the latter, all heart types listed have since been added to Rebirth.
