Abilities

Manifest Crystal Sphere

Trigger Three or more creatures remain in the Outer Ring for 6 seconds or longer; Effect Six spheres of crystal, each measuring 2 feet in diameter, manifest from thin air and begin quickly floating toward intruders. A sphere manifests at each of the points on the map indicated with a small numeral (labeled 1 through 6); the trap then rolls initiative.

Description

Shimmering, glyph-graven, two-foot-diameter crystalline spheres shimmer and condense in the air, launching with explosive force at intruders.
