This is, by far, the best automated D&D Character sheet I've ever used, and I've tried quite a few of them over the years. The relative ease with which you can add homebrew content, make minor adjustments to calculations using the Modifiers function, as well as the general layout and functionality of the sheet are truly impressive. I now use this sheet exclusively to create my characters. I also use it to quickly develop NPCs in the campaigns I run when I want them to have class levels. It's really an amazing tool for players and DMs!
