After the moment passed, and her taunts slipped their way into reality, helping her will to manifest, Avis summoned her weapon and her shield into being. A pale, scarred hand rose toward her forehead and then closed into a fist, grasping an invisible thread, and then pulled outward, her muscles tensing as she forcibly drew the contents from her own mind. At first it was simply a formless mass of writhing colors and flickering images but her other hand rose to grasp the almost intangible mass, and as soon as her fist closed it exploded into a glassy, mirrored shard with bloody cascades of violence and horror running over it's surface. A thousand images of murder and tortured flesh and a thousand more visions of demonic phantoms, all twisted smiles and sharp teeth, danced upon the yard long Sword in her right fist.
She readied the sword and then thrust out her left hand, with fingers splayed, and then slowly curled her digits inward, her will bending reality into a distorted orb that grew until Avis' shape wavered like a reflection in a distorted mirror. Air swirled around the orb, currents pulled inward, and other eddies thrusting outward to create a vortex that would deflect any unworthy attack.
Then, magical might made manifest, the warlock charged across the swathe of dueling ground and thrust her nightmare spike of psychic pain at Asp but the vicious, primal serpents protecting the Obrimos forced her attack away.
