I dont get the formula. Lets put some numbers in it.
(LK:10, Finesse, 3xMoreCriticals, Aiming at Eyes) so it should be 95% crit chance
[Critical chance] + (60% + 4*[Luck])/100*[Aim bonus] = 95%
[10+10+15] + (60% + 4*[10])/100*[60] = 95%
[35] + (60% + 4*[10])/6000 = 95%
[35] + (60% + 40)/6000 = 95%
[35] + (100%)/6000 = 95%
135%/6000 = 95%
0,0225 = 95%
There seems to be something wrong.
