Can the resolution mechanic use something other than dice, like coin tossing or rock-paper-scissor?
I think for this one I'd stick to the single dice type. However I'm not going to police people's submissions, as the restrictions are there for fun, not for hang ups!
I’d certainly interpret coins as 1D2 in this case, so I’d say it counts!
That's fair! I think a d2 is a valid choice :)
