Aeon Stone, Obsidian Annulus

Magic

Worn

The first obsidian annuluses appeared as protective devices worn by important Azlanti agents. While this aeon stone orbits you, when you are the target of a spell or spell-like ability, you can spend 1 Resolve point as a reaction to gain spell resistance equal to 11 + half your character level. This spell resistance ends after the effect that triggered your reaction is resolved. The aeon stone can’t provide you spell resistance for 1 hour thereafter, and you can’t gain spell resistance from any obsidian annulus during this time.
