I've met a problem, that I leveled up too fast and in most quests where monsters have auto-levelin system I deal something about 100-200 damage at most, using my only 2 counters to them to their thouthands hp (while others are from 20 to 50 damage at most), and enemies have 150-300 damage on each attack, for example here helping Miriam defeat the Mindflayer:
(if the screenshot is not seen, the boss here has 3270hp, while I have 2392hp, and my teammate has 2882 hp)
Is it somehow possible to lower my level or to lower their powerscale?
(This is my second run, and on the first one I hadn't met such difficulties)
