this is the formula used to figure out blocking % with a given amount of dexterity with a given amount of block % on shield

each characters block % number appears differently on the shield (some are same but ex: sorc is lower than paladin)

'Blocking'=the block % number on whatever shield you are using for your character

Total Blocking = (Blocking * (Dexterity - 15)) / (Character
Level * 2)
