Hi Duccio, according to the blurb on that sheet: (FFG) End of the World Character Sheet uses the Roll20 API to roll dice. The script can be found on the Roll20 Github or at <a href="https://raw.githubusercontent.com/dayst/FFG-EotW/master/EotW.js" rel="nofollow">https://raw.githubusercontent.com/dayst/FFG-EotW/master/EotW.js</a> This would require the creator of the game to be a Pro subscriber to enable access to the API.
