Medusa Mask

This intricate mask is made of gold-plated iron. Writhing snake tails radiate from a gemstone upon the brow, almost as if they were medusa-like hair. The mask grants a +4 bonus on all saving throws against visual effects, including gaze attacks and sight-based illusions. Once per day as a standard action, the wearer can cause the central gemstone to glow with pale green light, at which point she may target any one creature within 30 feet. The targeted creature must succeed at a DC 15 Fortitude save or be petrified for 1 minute, as if by flesh to stone.
