Cleric: I take out the mason jar filled with brain juice.
DM: Are we playing Cards Against Humanity now?

DM: You are wounded and almost paralyzed at the bottom of the pit, together with your bard ally and the giant worm-beast. What do you do?
Wizard: ...I teleport out.
DM: Very well. The wizard disappears in a puff of smoke and re-appears atop the pit's edge.
Bard: YOU BASTARD!

Wizard: I cast Fire Bolt at where I suspect the monster is.
DM: Roll with disadvantage.
Wizard: That's 18 or... 6. Gotta love natural 1s.
DM: You don't seem to have hit the creature in the magical darkness, but you do suddenly smell burning paper.
Wizard: Well crap.

Wizard: Prestidigitation saves the day again!

Cleric: I don't suppose I can heal the darkmantle?
DM: First you shot it with magic, then you tried to set it on fire, then you pierced it with a rapier, then you whacked it with a mace, and then you somehow insulted it to death, causing it to fall a hundred feet into an enclosure populated by giant acid-spitting bugs. There's hardly anything left to heal at this point.
