The Green Hermit
Hero
A friend of mine recently started a game, and he doesn't fine Inspiration uninspiring as a mechanic. He just finds it terribly difficult to remember int he middle of everything else.
I think he's instead defaulting to giving a PC advantage for clever play on the spot, rather than giving it to store up for later use.
I have fancy metal dice that I hand out for inspiration. They are easy to see and remember. If they haven't been used by the end of the session, we jot that down in our notes and they get passed back out next session.
