not sure if you figured it out yet or not but for the knight i found him incredibly difficult and i used a little cheat to actually beat him. you can save the game after every turn and reload so you can get the best damage on him and possibly more dodges, he does have a lot of damage so if you find yourself out of health potions and bind up is on cooldown then block its incredibly useful and if you're out of mana and health potions then you're kinda screwed at that point. make sure to stock up on potions from chet and do some farming for both xp and also materials to sell to chet the potion bag is also really useful as well in this fight. also make sure to upgrade your sword so that you can get that extra bit of damage as well if you havent. hopefully this helped and i wish you luck, if you did finish the fight then maybe this will be useful for someone else looking for answers. :)
