"Increases your chance to block by 25% for 10 sec. In addition, if your total chance to block or avoid an attack exceeds 100%, your chance to critically block is increased by the excess."
Am i missing something here? I personally have 11% dodge, 14% parry, 5% miss = 30%.
Disregarding the 3 lvl boss difference, what would be the point in going above 70% block?
