Yep keeping him out of the fight is another way, I didn't really figure out that I can do a status effect on him until pretty late in the fight and had figured out the lever mechanic already. I also didn't realize shock recharges him till I had Jahan shoot a lightening bolt at him and was like oh crap. His normal attacks are a bit painful so its probably not a bad idea to try to keep him out of the fight as much as possible.
I was hoping to have all 3 of the NPC's survive, but one of them charged it and died, I was still happy to have 2 guys survive though.
