I was doing a little bit of playing with character creation the other day and got a little bit bored of re-calculating the costs of the various attributes, skills, and talents each time. As a result I decided to make Excel do the legwork for me.
you will need to save this to your computer for it to work properly as it involves some fairly complex nested IF statements, it has also only been tested on Excel 2010 so I'm not sure how well it will work with older versions/open office/etc.
Its quite simple to use, select your Aptitudes at the top of the Talents Tab (don't worry it does stats and skills as well) and it should automatically adjust the costs for you.
