a dummy that look like a knight made of wood or metal scrap, next to it another wooden/metal scrap stand to hold a shield
players in the training hall can edit them (a computer next to the dummy to select his armors and helm and shield and can add uv's on them)

then you can test your weapons against those armors specific protections helping player to know the damage dealt in pvp and built a protection against a specific type of weapon he want to defend himself from in pvp. this will create new battle styles and loadouts in pvp else than skovers and vog and "gunslinger" set (yes i said it right this time)
