Wondrous item, extremely rare (requires attunement).

The Dreaded lich phylactery left behind a small black orb, the size of a coin. It's smooth, and cool to the touch. It is utterly black, except for the shine of light and perfect reflections.

Whoever wears this, either as a jewelry or inside a pocket, has the ability to watch right into the souls of living creatures, learning their feelings, intentions and even alignments.

-The user gains +4 to its INT mod.
The Soul Void can extract the souls of the undead once every hour. It purifies them and restores their spirits, resurrecting them and restoring their HP fully, returning them back to normal.

Notes: Bonus: Intelligence Score
