Example i have 4 pieces of iron armor: helmet, chestpl, legg and boots with different stats. And then i put them on myself in example this order: first boots then legg, chestpl and helmet and from this combination i get 5,5 armor bars, but if i were to put these armor pieces with same stats in a different way i would get more or less armor bars. Even if i remove 1 armor piece from myself and put it back on armor bars will sometimes change to better, same or worse.
Like i dont understand how this works, can someone explain?
