[Context: we have just started the Curse of Strahd campaign, and my characters are in the dungeon called Death House. They’ve already learned not to trust me (the DM) after having to get to the top of a four story house before finding a way to the basement. They are now facing a well in the basement dungeon. There is nothing special about this well.]
Barbarian: I throw my moss agate down the well.
Me: Okay. It falls for a moment and then hits dry ground.
Barbarian to party: Okay, I can hold a rope and lower you guys down. Then I’ll jump down after you.
Me: How are you going to get back up?
Barbarian: *shrugs*
Me: Maybe you want to lower one person down first to see if it’s even worth going down?
*the barbarian lowers our 4'7" paladin down into the well.*
Me: With your dark vision, you find yourself in the bottom of an empty well. And…
*the party leans closer in anticipation*
Me: there’s a rock on the ground.
Barbarian: hey, could you pick up my rock for me?
