I made up most of the boons on the spot. When playing with the published material they’re built right into the color text. Like in Wilderlands there’s a crazy old hermit who lives in a tree. A lot of the color text is all the faux pas you can do that will make him attack. Other color text is about being caught out in the storm. Then there’s the axe. So the boons pretty much write themselves. Plus it was generally easy to add more on the fly based on what actually came out of the roleplaying. Like if a player role played being condescending to the elf King and failed the roll, I might respond with something like “choose your next words carefully if you don’t wish to wind up in my dungeon” and boom that becomes the next boon…avoid being thrown in the dungeon.
