[KCD2] I get one it from everything.

Need help what do I do in this game I try to do side quest and main quest but everything I do it's like I'm super under leveled but I don't understand how you level when everything I fight just destroys me in ether 1 hit or just stun locks me its very odd to me like I'm trying to do fist fight with Tibor did the sleep potion like it wanted me to do and he just still stun locks me and wins same with any wepon fight get one hit in the bam dead in one swipe like game is super cool but I'm to the point where I might just quit I domt understand how to level when everything just shits on you makes 0 sense
