@true_shinkenbut a short sword can qualify as both, right? That's correct.

@mikemearls It was mentioned that Kensei weapons are not Monk weapons. Does this apply to the shortsword? Or is that an exception?

A better explanation – a kensai weapon is not automatically a monk weapon. #wotcstaff https://t.co/hvIGagpMBa
