Lesser Ring of Resistance

Description
This brass embossed ring functions like a Ring of Energy Resistance and 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 the ring’s resistance value from the damage dealt. However, a Lesser Ring only grants 5 points of resistance.
