Player: "Why did a nat 1 let me find the magical item?"...
Was running a one-shot the other day for a novice group of players, and had a funny story I wanted to share. To keep it brief, the party was snooping around in an NPCs quarters looking for some good gear to pocket. I had a player roll an investigation saving through which resulted in a nat-one.
As a result, I told them "You find a hand to a petrified hand! One what emits power like no other"
This was when everyone suddenly was confused as if I just made a blunder. the table started to question "but I rolled a nat-one?", and I simply responded with "I know"... and then suddenly they found a petrified chest- a petrified foot- and a petrified head! They were finding the pieces of Vecna, and were consumed by greed that they didn't know I was tricking them.
You should have seen the look on their faces when suddenly the paladin is blasted with a power-word kill, and animates back as a death-knight!
Sure the party was a bunch of level ones, and this was their first time playing; however, they critically failed their investigation saving through what else was I to do? Anyways... after a TPK, I made sure to explain to the players that it was all their fault & they should have used their heroic inspiration dice to re-roll.
Everyone clapped and applauded me for my best DMing in the world, and I even got to meet all of the world leaders and shake their hands! My next session will be at the UN, and I'll be running Curse of Strahd.
Cheers!
