Freeing a Soul. Casting a spell that removes a curse on a
soul coin frees the soul trapped within it, as does expending all of the coin's charges. The coin itself rusts from within and is destroyed once the soul is released. A freed soul travels to the realm of the god it served or the outer plane most closely tied to its alignment (DM's choice). The souls of lawful evil creatures released from
soul coins typically emerge from the River Styx as lemure devils.
A soul can also be freed by destroying the coin that contains it. A
soul coin has AC 19, 1 hit point for each charge it has remaining, and immunity to all damage except that which is dealt by a hellfire weapon (BG
A, page 223) or an infernal war machine's furnace (BG
A, page 217).
Freeing a soul from a
soul coin is considered a good act, even if the soul belongs to an evil creature.
