Sadly, that is some of the dumbest rules I have seen to date. Mostly do to the fact that 500 cm2 might work for some katanas, but there size varies slightly, between 63-70cm blade length, not counting thickness nor width variation. And the armor jacket sizes might work for average human or elf, but what of orcs or max strength humans? My point, is that it is excess math that is not needed. But, that is my opinion, I know this. Thanks for translating it.
