Ring of spellbattle

Aring of spellbattle, also called a spellbattle ring, was a magic ring that gave its wearer the ability to dispel certain spells.

Description
It was a gold ring inset with silver spheres.

Effects
Its wearer immediately became aware of any use of, and the nature of, magical spells, powers, or psionics within 120 feet (40 meters) or 60 feet (20 meters). If the wearer knew spellcraft, it was possible that he or she could identify the spell, even if he or she could not see it at all.

He or she could then choose to dispel it as if with dispel magic as a counterspell, or else change the target of the spell, once per day, but only to new targets within 60 feet (20 meters). Otherwise the redirection failed.

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.
