Scapular

Scapular is a passive item.

Effects

 * Once per room, when Isaac is reduced to his last half Heart (either red, soul, or black), the aura around his head temporarily vanishes and he is granted one Soul Heart.
 * After re-entering a room, the ability can be triggered again.

Synergies

 * : Isaac can use the regenerating health to easily get the full damage bonus out of Bloody Lust by intentionally damaging himself.
 * : If Isaac has half a red heart after taking damage while charging, he will teleport and gain one soul heart, which can be used to teleport infinitely.
 * : At half a red heart, Isaac will teleport out of a room whenever he takes damage and will automatically gain one soul heart.
 * : If Isaac only has half a heart left and can access a reliable source of repeatable damage (e.g. fire or spikes), then this can be used to recharge an activated item as many times as wanted.
 * : The IV Bag uses Soul Hearts when at half a red heart, which can be used to obtain unlimited money.
 * ,, : Allows Isaac to gain infinite money or pickups using a source of repeatable damage.
 * : Isaac can have unlimited spiders if he finds a reliable source of repeatable damage.
 * : Reduces all damage to half a heart, allowing Scapular to activate every room as long as Isaac enters each room with more than half a heart.
 * + : Infinite item recharges. At half a heart, Isaac will gain a soul heart, which, upon activation of the activated item, will trigger the Sharp Plug damage, which will be absorbed by the Soul Heart, causing the Scapular to trigger again. Without The Wafer, Sharp Plug will kill Isaac.
 * : Will leave Isaac with more protection immediately after triggering the effect of the item by having his health reduced to one half heart.
