Yes, but they were from 3E, when dungeons were important to WotC.Both are in Tales of the Yawning Portal.
Which ones?I also think Phandelver has good examples of dungeons,
We will have to agree to disagree on that one. I don't think DotMM is well designed.Undermountain is full of good examples for high level,
I have not read that one.and Tomb of Annihilation is a good example of a deathtrap dungeon.
Which ones? I own Candlekeep, but not the others.They also have several other anthology books with decent dungeons in them.
