Since posting it a few months ago, I’ve been continuing to add new content to my Age of Terror hack for using the Dragon Age RPG to play in the world of Diablo. It now contains 16 backgrounds that should cover all of the character classes from the computer games, a few new talents and spells, a random magic item generator, and a growing bestiary. Up next, I’m planning to work on filling out the bestiary and grimoire chapters a bit more.
You can view the pdf here. As I add more material, I’ve been updating the pdf in place. If you read through it, please let me know if you have any feedback.
EDIT 25 May 2020: The old Dragon Age version of this Age of Terror is no longer available, but there is a newer Fantasy Age version if you check the most recent posts tagged Fantasy Age. Dragon Age Oracle is also no longer online.
