First of all u gotter find the values of the weapon ur holding, ill help u and tell u them

BX= 160
BH=240
WizMS20=64
Once u have found this value u can then alter it and it will change the item ur char appears to be holding, once this changes to a weapon calss u have 100% with, it will then let u crit with the weapon u are really holding.
This is quite cool when using a GiS as u can change it to an esterk and get 4 range crits. Or if ur 100% archery u can crit the screen distance with archery/wand class weapons

If u set the value to 0 i think u get Crits and dash with anything, havent fully tested it though...
Hope that helps.
