Cheers for the help.64 hours and counting,at least ***i can murder him with Sal now*** .
I don't know how the "fancy mathematics" of the drop rate works, but killing him with another character don't make the process start from the begining?
no. each attempt is %100 independent from all other.
it could drop at attempt 1 or attempt 10,000 or any attempt in between (or beyond if you are really unlucky)
killing him more does not increase your drop chance. it only increases the # of times you have rolled the random # generator dice to potentially have it drop --- Crazy? Crazy with low prices on Wind Brahmin. You buy one!!
