This is a character building tool I built and thought it might be helpful for some of yall out there. It allows you to quickly input Race, Skills and estimated final skill levels to determine the builds final level and final attributes. It also has a spell cost calculator.
I've found this very useful when testing different ideas as you can quickly find out if the skills the build levels up will give you enough perks or how to best balance attributes for builds that need all three. Mods shouldn't affect this unless they change starting skill bonuses or how much attibutes you get on level ups. Hope this is helpful.
