you can use an upgraded skulders (around 14xx def) since you're a sorc. it adds some extra mf if he gets the kill. and you should lvl him so that he's about your lvl to do decent damage. chances are he won't max out resists, so find a veil of steel for helm (50 all res), stone armor (15 res), or if you can, get a coa (20ish res). if you can afford eth bonehew, might as well get a reeper's tolls.
