Only in shields the block armor gets higher when upgrades them
2 handed ( that gots a buff from previous version )or other weapons not , just stay in the base numbers thats are quite high in 2 handed but not to high to be better than a shield of the same tier ( example black metal atgeir have 104 block armor and black metal shield 135 , iron atgeir 56 and iron buckler 100 )
And stamina usage gets lower with your axe skill gets high
