Hussar
Legend
If the players can't explain why something should work, then it's their imagination that has failed, not the DM's.
If a player wants to try something IMC, and gives a plausible in-genre explanation why it could succeed, then I will give it a chance to succeed. The player has successfully used their imagination.
If the player just says "I roll an X check" with no explanation, they have failed to exercise any imagination & they deserve to fail.
Or do you think only the DM has to exercise imagination?
Umm, no?
Player: I want to get past the guard. I'll bluff him by pretending to be a spy sent out by Baron Von Badass and just now returning with important information for the Baron.
DM: No, you fail. The Baron has left strict orders to not let anyone pass, so, you have no chance of success. Since the Baron will punish the guard's family, I cannot see how you could possibly succeed here.
Yeah, the player has totally failed his imagination.
