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 access to the second and third endings of the game. Once the player has acquired the Void Heart, they cannot access the first ending without starting a new game.

The player's Shade and Siblings are no longer hostile to the player and deal no contact damage. They can always be destroyed in one hit. Siblings will return back into the ground after a short period. Void Tendrils will no longer appear, and the player can safely swim in any pools that previously had Void Tendrils in them.

This charm replaces the Kingsoul and cannot be unequipped; however, it no longer uses any notches.

How to Acquire
The player must Enter The Abyss with Kingsoul equipped. A part of the floor will rumble. The player must then smash the floor with Desolate Dive or Descending Dark and explore the revealed cave until they find a cracked black orb, and hit the player character's reflection with the awakened Dream Nail. Complete the dream and the Void Heart will automatically replace the Kingsoul.
