Soul Lock Once per day as a full-round action, a cacodaemon can ingest the spirit of any sentient creature that has died within the last minute. This causes a soul gem to grow inside of the cacodaemon's gut, which it can regurgitate as a standard action. A soul gem is a tiny-sized object with 1 hit point and the same AC as this creature. Destroying a soul gem frees the soul within, though it does not return the deceased creature to life.
