After we out the last few stairs to a guard tower, around sixty guards gathered below us to try and get up the stairs.
I cast prestidigitation to make it look like there was an extra stair
I yelled “Come and get me!” and rolled a nat 20 on Persuasion.
All sixty guards fell for it and died by falling down the tower.
“I JUST KILLED SIXTY GUARDS WITH A CANTRIP, AND I CAN’T EVEN PRONOUNCE IT”
