Ring of spellbattle

A spellbattle ring was a magic ring that gave its wearer the ability to dispel certain spells. Its wearer immediately became aware of any use of, and the nature of, magical spells, powers, or psionics within 40 m (120 ft). He or she could then choose to dispel it or change its target. The ring also granted the wearer the ability to affect spells that were activated by a spell trigger or similar mechanism, but did not affect discharges or psionics from magic items.

A ring like this was possessed by Ahbhaer Mhilshoun.
