ahh... but the 2 handed sword isn't being used it is nominally designed to (i.e. using the proper skill for it), but as part of a weapon kata (adv. MA skill).
it makes the Martial Art more deadly (which is its primary purpose...).
but if I need to I can make a small addition (i.e. "Base Damage for the Kata is equal to 4+ 1/2 the weapon's Base Damage OR the Weapon's Base Damage, whichever is higher".
That would still be better than having a pole arm doing 15 points of Base Damage...
