Hello,
Firstly thanks for Barnabas the Dog updating the previous version of the spreadsheet.
Secondly i found the spreadsheet to be kinda lacking so I decided to make few improvements, updates and fixes to the spreadsheet. I only did changes to the first tab and these changes include new formulas to calculate stuff, extended statistics, full spell book, tooltips, some hidden tips, protection of cells, propably spelling errors ( English not my first language =P ) and some eye hurting coloring.
