That's awesome, Max! I'm glad you guys had fun — and thanks for the feedback. ^^
Did you use Effort just for tests, or did you also use it to establish facts? I'm curious how that would work with a pre-written adventure.
They used it for test a lot, i used it once to establish facts and to have a grappling hook in the carriage (it was a minor fact). Nobody tried the "prophecy" stuff... (which is an interesting mechanic anyway)
I used a house rule of "if you spend some effort on a perception test about something, i tell you what there is to know about the thing you ask, no roll needed..."
