One of my favourite stupid D&D tropes is low-level adventures inappropriately scaled for high-level parties, or vice versa. Like:
- The thousand-year-old prophecy has come to pass, and a plague of dragons has descended to bring ruin upon the kingdom. The dragons in question are six inches long.
- The party’s been asked to chase some rats out of the inn’s basement. Upon investigation, the basement contains a passageway to the underground temple of some forgotten elder god; the temple’s strange energies have transformed millions of rat into a vast hive-mind whose sorcerous machinations will crack the planet in half if left unchecked.
For the second - Did you mean Warhammer: Vermintide?
Nope – it’s not rats-in-a-basement anymore if you make them big gross rat-men with swords. It’s essential that they’re still just plain old rats; the problem is that a. they’re telepathic, b. there’s about a million of them, and c. in sufficiently large groups they can cast 9th level spells. Have fun with that!
