If there’s no chance of success, don’t make an ability check, since rolling a 20 isn’t an automatic success for a check. #DnD #rulesreminder

@Nova_Bomb_Ninjaif I roll a nat 1 on my insight check, do I still believe you? Funny you ask. A natural 1 is irrelevant to an ability check. Your total is what matters.
