+9 Rideword is nice for leveling. For killing with AS, +9 Evil Marching, that zodiac headgear that adds to % range when over upgraded, or anything that adds + to % range. For Warg skills, pretty much most dmg comes from stats and weapon. If you can cast AS fast that you won't need phen, you might want to try MOH or Bow Thimbles. The rest are ok, enchants would be nice and overupgrading the WW armor helps.
