Well, if Kamrack Essence A requires 25 pieces, and Kamrack Essence C requires 75, it might be safe to assume that Kamrack Essence B (presumably a mixer) requires 50 pieces. However, with only three other Kamrack bits to date, no amount divides equally ... and we had better hope it's not 50 of each. :evil:
I know that is of no real help, but I felt like posting.
There are three different 'mixer' types dropped by the monsters - it is possible that it's not just one item we make, there could be an Essence D as well ...
