the world i'm building is *basically* primitive, with no mention of cars/computers/airplanes/etc. it's very middle eastern in feel (like saudi arabia or egypt, perhaps), a desert, and the weaponry used is pre-invention of the gun. so there's knives and swords and bows, but no gunpowder or modern weaponry.
so here's my scene: there's a gladiatorial-esque exhibition match between two assassins that is being viewed by a very noisy crowd of soldiers, assassins, mercenaries and warriors. one assassin uses knives exclusively. one uses brute force (with the force being accentuated by a set of... armored gloves, which also increases the force of his hits). they are to disarm and use something similar to yawara/pasak/dulodulo
as a blunted method of exhibiting their skills and 'kills'.
now that that's been set up, here's the question.
is it possible to allow these to flare/light up/ding/make a *loud* noise/etc when they are used in a killing move? that is, to say, for example, if the stick made a motion that would be a throat slice on the opponent, could it light or flare or something? or, for a change of character, could it ding really loudly if mr. brute force made a punch that would stop the heart (for instance)?
or, because there is no mention of other technology, would we have to rely on the honesty of the assassins involved, and the judges of the match?
all help is greatly appreciated.
