Jace is incredibly intelligent and capable of such talents as clairvoyance and illusion. His specialty, though, is in the art of mental magic which makes him unique within the multiverse. He has a reserved nature and a troubled conscience for the poor decisions he has made in the past. Curious, and always in control, Jace is a master of mind reading, illusionism and memory modification. His telepathic powers allow him to manipulate enemy mages by countering their magic or using their spells against them. He is mostly self-taught, as he has a habit of losing or deleting his memories. An adept analyst, he has an optimized plan, and a backup plan, for every situation.
Jace is a slender young man with unkempt brown hair. His white facial tattoos were created by the Ravnican Gruul who took him in as a child. On his cloak, he sports a symbol derived from it: an elongated ring, open at the bottom, with a circle floating in the middle. The symbol represents a sphinx's collar, which for a long time was the one remaining memory of his home plane.
When creating spells, Jace's eyes shine bright blue with magic. He usually tries to avoid physical combat.
