honestly i tough he was a troll, and even if the combat system is not perfect is still a masterpiece
The combat system is legit. Just needs you to pay attention to each move's reaction.
I managed to defeat dark knight easily (lvl 20 or lvl 1 virgin but hecka upgraded items using soul gems)
I use android so no cheating for me. After all achievements, I max Strength and then agility. Perception on 4 + 2 points on surveyor scouts everything. Magic 1 for start. And endurance 5 in more than enough.
All out blitz should be for enemies with no shield (it's easier to block) and assault for shielded.
Of course I would have cheated the shit out of the game but you need your device rooted for accessing game files. Which mine is not.
