Dragon Mountain (1993)

From the web:

A "Deluxe Boxed Set" adventure for character levels 10 to 15, this Advanced Dungeons & Dragons (2nd Edition) supplement pits a party of adventurers against the subterranean denizens of a mountain and their mistress. Players will need all their wits about them as they face cunning foes, deadly traps, puzzling conundrums and, of course, one very nasty dragon.

The ultimate DUNGEON MASTER fantasy! This is the most deluxe dungeon, designed to appeal to discriminating and demanding role-players. Adventurers, beware. This is more than just a dragon hunt. Within the lair of this beast lie cruel and deadly traps, befuddling conundrums and puzzles, and cunning minions that will be the end of overconfident or careless adventurers.
