This white gold ring is forged in a braided pattern. A single ruby set in its center flickers and pulses with magical energy.

A ring of greater counterspells can hold a spell of 1st through 6th level, much like a ring of counterspells. You cannot cast a stored spell out of the ring, but should that spell ever be cast upon you, it is immediately countered, as a counterspell action, requiring no action (or even knowledge) on your part. This use causes the ruby stone to flash once and uses up the stored spell. Once it is gone, a new spell (or the same one as before) can be placed into the ring.
If you are a spellcaster capable of countering a spell on your own, you can also access the ring’s secondary ability. Once per day as an immediate action, you can attempt to counter a single spell cast by a spellcaster you can see, provided he is within 100 feet. Like the ring’s other ability, this one requires no preparation or knowledge on your part. You need not make a Spellcraft check to identify the spell being cast, and the spell you use to counterspell can be of any level. This counterspell attempt functions like greater dispel magic used to counter a spell, except that you add your caster level to the counterspell check (maximum +20). Thus, a 12th-level wizard wearing a ring of greater counterspells would roll 1d20+12 when activating this ability. When you activate this secondary effect, the braids of white gold seem to twist and writhe on your finger, and the metal glows faintly is if it were growing hot, although you feel no heat.
