My advice, using atmost x2 or x3 dmg, leave defense alone, infinite skill is depend, don't get on the leaderboard, don't use it in coop,try to stay in possible range and not just turn up the mod if it get hard, basically use it as a helping tool not as crutch, don't draw attention to yourself...
Should have know better (hoyoverse even said it) got banned cause buying the artbook, thankfully only 30 days, so if you don't want to get banned do not buy the art book
