I disagree. DM’s always have the ability to put in their own choices and, in this case, room descriptions, regardless of what a module says. But that is work, and one of the things you buy a module for.

To make an extreme example, imagine I sold a campaign module called Blank Slate, where every page just says “and then you decide what happens next” and “decide what rooms are in this dungeon and what monsters are there.”

That’s awesome, reminds me of one of my favorite scenes from the Bourne movies. Bourne knows some agents are coming after him to the building he’s in, so he picks up a phone, calls the police and says “I heard gunshots, I think they’re Americans” and then throws the phone against the wall, fires a few random shots, and leaves. The police then catch the agents sneaking up to the building and arrest them.

If it were me, I’d find it easier to change the lore so you can do planar exploration at lower levels than to deal with all the mechanics and balancing of level 20 characters

Just me or does something look wrong with that finger?
