small fun idea: add barbarian-style "bearskin-armour" or something similiar which dont have a normal "armour" value but simply add a few hitpoints.
whats the point? they would have a different function than normal armour, compared to normal armour less vulnerable against blunt or pierce but less protection overall.
not necessary at all, but I would like it and would be a way to implement attractive low to med-tier armour.
