Wow that's impressive! :D You must be the only one who has seen the cutscene!
It is very hard to balance this kind of game now I realize. Later on, I may go with simplified version of an already working system like dungeons & dragons battle system to not to invent the wheel myself.
Even with full dexterity, there is a chance to miss that roll. Especially when opponent's dexterity is also very high.
Thanks a lot for feedback and your nice words :)
