そういえばダメージ軽減の上限10っていつまでも言われてるけど今は間違いだよな
 For example, a full suit of diamond armor reduces damage from attacks by 80% --
if each piece of armor also had a Protection IV enchantment (EPF 5 each), the enchantments would further reduce damage by 40% to 80% each time,
for a total damage reduction of 88% to 96% (i.e., 80%, plus 40%-80% of the remaining 20%).
