This reddish iron ring continually protects the wearer from damage from one type of energy—acid, cold, electricity, fire, or sonic (chosen by the creator of the item; determine randomly if found as part of a treasure hoard). Each time the wearer would normally take such damage, subtract 10 points of damage.

Prerequisites: Forge Ring, resist energy.
