Brittle Bones

Effects

Grants 6 empty (Bone Heart) Bone Hearts.
Removes all Red Heart containers. Does not remove existing Bone Hearts, but does empty them.
Upon losing a Bone Heart, including ones acquired from other sources, Isaac fires a ring of 8 bones that split into more bones and gains a permanent +0.5 tears up.
- Each bone does twice Isaac's damage plus a flat 22 damage; split bones do half this amount.

Picking this item up as (The Lost) The Lost or (Keeper) Keeper will give a one-time +0.5 tears up ((Added in Repentance) +0.4). This bonus is retained even if the item is later lost or rerolled.
- Keeper will also gain 24 Blue Flies.
(Added in Repentance) The tears up bonuses gained through this item will persist in the escape sequence of (Mines) Mines II.
(Added in Repentance) Losing Bone Hearts through a Devil Deal will not give the tears up effect.
If Brittle Bones is removed (such as with (Tainted Isaac) Tainted Isaac), existing tear upgrades will not be removed.
