Book of Phantoms item
Book of Phantoms is an active item in Battle Fantasy, a mod for The Binding of Isaac.
Description
Removes all of Isaac's heart containers and red health, and gives 
Soul Hearts until he has 6 of them.
If the item has been used more than once, the item will permanently decrease Isaac's damage multiplier by 0.1×. This damage multiplier can not go below 0.1×.
Each 
Bone Heart held decreases the number of Soul Hearts the item gives by 1 per Bone Heart.
When used as 
Bethany, instead removes all of her heart containers except for 1, adds 18 Soul Charges, and consumes the item.
