The ark is really hard as a battlemage, but it can be done, finding the tesla emitter will help. Look in the rooms on the way to the force belt for both the flexifiber robe and the tesla emitter. That's where I found them both, after about 3 or 4 runs, it took me ages. Your gear looks good, take loads of shock potions for the steel wizards. And use the med bays and an ancient battery to prime you before any major encounters. Your dps looks really low, how's your agility? High agility is essential for using a wand, and more useful than a staff, imo, trait boosting for the staff requires strengh, a muscle bound mage appears comical in my imagination.
