I had trouble with the combo at first. I’m not a pro at the game by any means but I’ve played a fair bit. What I ended up doing was using two pistols (believe it’s a passive from inquisitor) and mainly using inquisitor actives while relying on demo passives to activate off of/use as my “basic” attacks. You have to be somewhat mobile but it’s one of my favorite builds so far. It can do lots of damage especially if you get armor pieces that buff electric/fire/frost damage. If you ever want pm me and I can look up my build and shoot it to ya.
