No instant win!
This means, you cannot just jump out of a bush and slash enemy in chest, that's a bit annoying. You must jump out of a bush, and run towards the enemy trying to stab him.
No Godmoding
You cannot dodge always, you cannot hit always and you cannot win always.
No Killing
Remember, you cannot kill your opponent.
No Body Part chopping
Lol, we don't want if someone is gonna chop a arm or head off of our characters. That's why, you can only stab, slash, but Not chop the opponent. (Unless he is a Non-Player Character)
No instant hit
You can only TRY to hit. The opponent will decide either he is hit, or does he dodge. But if he dodges too much, he is Godmoding.
