This amulet is a small iron circle with five gemstones embedded in it. The amulet can be worn by anyone but will only function for an arcane spellcaster capable of casting Dispel Magic. Making use of the amulet requires wearing the amulet for 24 hours. After one has done so, whenever one counterspells a spell of at least first level, an additional gem in the amulet lights up, storing a small amount of arcane energy. Whenever you cast a spell you may expend one gem as a free action to increase the caster level of the spell by 1 for purposes of penetrating spell resistance or for 1 for purposes of duration. Also, whenever you cast Dispel Magic, or any similar spell, you add the number of lit gemstones to your dispel level check.

Removing the amulet for any amount of time immediately causes all the gems to cease glowing, and the amulet will not function again for 24 hours.
