Much like with Leman Russ, who was also impervious to magic, Gilgamesh would probably kill Magnus. Magic is Magnus' thing, and even casting enhancement magic on himself to improve his speed and strength, he'd still be too unskilled to hold out in physical combat against a melee expert. The only catch is that Gil would have to have a weapon that could do significant damage. Mag's daemon form is much more durable than his mortal form ever was.
