How much dex for max block??

I'd like to know how much dex is needed for max block on HoZ and every other shield in the game, because it's so confusing when i see "enough dex for max block" :S

Thank you

you need more dex for every lvl you lvled. so 75% is max, after you max your block then after every lvl you need put more dex!!!

Total Blocking = (Blocking * (Dexterity - 15)) / (Character Level * 2)
(blocking = shield block + armorblock + holy shield)

Or, rewrote as:

Dex=(Clvl*2)*T+15
____________
B

(t= Total Block) (B= Blocking)

I'm pretty sure that's right. It's been a LONG time since I did any real equation work.

Thanks for the help guys
