You gesture at a dark spirit.
The seethings of the Red Spiral resonate with your spirit.
The base of the dark spirit's right arm suddenly explodes in a flurry of strobe-like red lights, propelling the now-useless limb a good distance away where it is engulfed and consumed by remnants of spectral starry red fire.

A warm feeling of serenity and approval washes over you, and you sense that the Immortals are pleased with your efforts to eradicate the accursed legions from Elanthia.
The dark spirit twitches violently, then ceases movement.
