Alright everyone! After some work I got the Roll20 sheet HTML set up. What this means is if you pay for the $9.99 USD/mo level on Roll20 you can add our HTML code to the custom character sheet there in the Campaign Settings of your game, thus allowing you to keep track of everything via a virtual Roll20 Character Sheet. This sheet has buttons/macros already set up, allowing you to roll in the Roll20 sections as with other character sheets. While not the fanciest of character sheets, it works well for now until we can get an official character sheet and PDF set up with Roll20.
You can find the file below, it is in HTML format but can be easily opened with Notepad or Notepad++. You would then simply highlight then copy and paste the code exactly as it is over to the custom sheets section of your campaign. After saving your campaign settings, your new character sheets will use this sheet!
Here are the official steps for adding custom sheets posted by Roll20.
To edit a custom character sheet for a game:
Select the Games menu, and select My Games.
Select the game to go to the campaign details page.
Under the Settings menu, select Game Settings.
Select Custom from the Character Sheet Template menu.
Enter in the copied HTML
Once you have the character sheet added to your campaign, you can continue to use it even if you cancel your future monthly payments with Roll20 as long as you use the same game. I'm continually working on the sheets to update them as I go, if there is a feature you think needs to be added, I will see if it is something I can add!
