all cripplers need 10 luck, it is a must if you want any sort of chance to get good criticals man, the +3%, +5% and the +7% values per point of luck are important beyond point, therefore this
10 Lk no extra boosts, the critical chances
Eyes: 70%
Head: 50%
Limbs 30%
Ultimate crippler build (10Lk, 3xMoar Critz, Finesse)
Lovely critical chances, eh?
Eyes: 95%
Head: 75%
Limbs: 55%
At least that's what I have been calculating my builds with so far...
