I spent a while creating an excel D3 character sheet because I like doing that kinda stuff :p Eventually I will have a sheet for each class, but it started with the Wizard. There's a bunch of dummy data and functionality based off our knowledge of D3 pre fansite visit (so it has trait and skill points). It will also be updated to reflect D3 once it's released (along with updating the fake stats and items with real stats and items). And lastly it runs a little slow on some computers due to the dynamically updating images so I'd actually like to know how many people it affects. I can remove the images and replace them with text to speed up the doc, it just won't be as cool.
You need excel to use the doc, other than that you can input your characters level, skills, traits, gear (including the ability to make your own rare items), aura's and gems and it will calculate your characters statistics and damage output.
Let me know what you think or if you find any problems with it.
