@CarsonAtwood How about for that same character's most feeble skills? Something that is not impossible for them, but out of their area of expertise. 20%? Lower?
@CarsonAtwood What sort of probabilities do you generally prefer for player characters to have on dice rolls? Of course it all depends on the game in question - but let's say a game where characters are pretty competent from the get-go, not super-heroes level, but not buffoons.
