Do something else

You can probably come up with variations on these methods, or entirely new ways to choose between the potential results.

For my "take shrooms near a waystone" move, I've identified a potential good result (feeling a profound sense of connection) and a number of potential bad results. Seems like it'd make sense to have each player roll (+CON, maybe?). On a 10+, they get the good result. On a 7-9, they pick one of the bad results. On a 6-, multiple bad results. (Maybe? I'll come back to this later.)

But no matter what they roll, they'll be hallucinating and be able to both see (some?) spirits and access the Fae paths.
