Revenant

Revenants have returned from death, usually to accomplish some specific task that they valued in life.

Special abilities
A revenant has 5/+1 damage reduction and 100% immunity to acid, cold, and electrical damage, but has 100% vulnerability to fire damage. This creature has most of the usual undead immunities, specifically immunity to critical hits, disease, level drain, ability drain, mind-affecting spells, paralysis, poison, and sneak attacks. (Immunity to death magic is missing from this list.) Furthermore, this creature regenerates three hit points per round and has a turn resistance of 10.

A revenant can use its paralysis gaze once per day.
