Wow, most drastic digression ever from the OT. My apologies...The cave is riddled with over 600 magic mouth spells. Detect magic will go off like a siren. Its a honeypot.

That said, with all due respect, this strikes me as a misreading of the scenario. Certainly, from how my players reacted (and I don't really editorialize when DMing), a "cavern full of overlapping magical auras" is not really that interesting; to them, it has meant "an area covered in traps," "an area covered in Nystul's magic aura spells," or "an area that radiates weird Underdark magic just like those places that let the drow weapons and armor work or let our magic contact lenses function." If there were specific detectable sources of magic in the cave, I would agree 100%, but, especially coupled with the warning, this seems like a setup for an easily avoidable encounter.
