Aeon Stone, Obsidian Annulus

Description

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.
