+1 Ring of Protection

A ring of protection improves the wearer’s Armor Class value and saving throws versus all forms of attack. A ring +1 betters AC by 1 (say, from 10 to 9) and gives a bonus of +1 on saving throw die rolls. The magical properties of a ring of protection are cumulative with all other magical items of protection except as follows:

1. The ring does not improve Armor Class if magical armor is worn, although it does add to saving throw die rolls.
2. Multiple rings of protection operating on the same person, or in the same area, do not combine protection. Only one such ring—the
strongest—functions, so a pair of protection rings +2 provides only +2 protection.
