Void Heart

Description
An emptiness that was hidden within, now unconstrained. Unifies the void under the bearer's will.

This charm is a part of its bearer and can not be unequipped.

Function
Allows for two different endings

Your soul doesn't attack you anymore when you die

Siblings no longer attack you

This charm replaces Kingsoul and cannot be unequipped. It doesn't use Notches.

How to Acquire
Enter The Abyss with Kingsoul equipped. A breakable floor will appear. Smash the floor and explore the revealed cave until you find a cracked black orb, and hit your own reflection with the awakened Dream Nail. Complete the dream and the Void Heart will automatically replace the Kingsoul.
