I was being generous with the 12 hours, i did mention 6 hours to gather everything required, and if you have a mine very close then you can easily supply the furnaces as and when.
Still, the maths is quite easy and many other look it, Nice talking to you, and my theory about the KaKa cloning was right

So to stop the KaKa, you must cut of the cloning production and not hunt the clones themselves, so for all you people out there this is the way you kill the beasts, you cut off the head.
Kaka, i have the up most respect for you, the role you play, and you play it will. This is of course a "role playing game".
Untill maybe one day we meet. Good luck in your hunt, may the spirits be with you and with me.
