This is in NO way a finished worksheet. I'm still working out some of the actual combat numbers. If you have the Attack and Defense variables figured out in combat, let me know, I'll them to the spreadsheet. I would have thought they are multipliers or at least act as a coefficient. But it's possible they are just additive. When I have a closer idea of how the numbers work, I'll begin to finalize the labels on everything to make it a little more user-friendly. I've cleaned up the spreadsheet and tried to make it a little easier to use. You will need Excel 2007 to view. I have not tested it in GoogleDocs. -Edit May 3, 2009 --removed code per forum rules. You'll have to look for it in the code threads.
