But it shouldn't matter.. The player should only care about beating it. He shouldn't have to factor in extra rules like No hiding behind rocks, or no protecting yourself with distance or terrain.
See, this is where it breaks down and gets stupid.. If you were fighting a monster with a crappy sword, would you go toe to toe, or would you use your head and try to out smart it?
Humans are squishy and don't have fangs, venom or claws.. It's natural for them to try to outsmart their opponent or to find some other advantage.
