I'm bored with all kung-fu inspired monks in RPGs.
Monks could use greek pankration. Greek soliders were taught pankration so if they lose their weapons/shileds they could defend themselves by punching, powerful kicks and takedowns. Hence, why greek armies could often defeat more numerous opponents (besides tactics, etc pankration would help greek soldiers in battles).
Besides using ancient form of boxing (and kicking), pankration also used wrestling which involved quick and efficient takedowns which would always end with moves which would break opponents necks or limbs or with strikes to the neck, groin, eyes, etc.
I think this would work nice, esp with monks having their bodies enhanced by life-long training and meditation which would unlock physical (strength, agility, resistanc, etc) powers coming from their soul or from praying to a certain god.
