Every Dungeons Needs _____ and No Dungeon Should Have _____
Is there one thing that the failure to include it in a dungeon adventure will lead to a less fun experience for all?
Is there something that should never be in a dungen adventure, but often is?
These don't need to be physical items, but they could be themes or whatever.
Rats and coppers are invalid answers ;)
For me, most every dungeon should have a treasure room. It might not get found by the players, it may be found but overlooked, it may have a false analog to fool the players, but generally speaking, there should be a treasure room. Heck, it might not be usable treasure. It may have been valuable at the time the dungeon was built / created but now has little to no value due to deterioration, change of valued metal types or the like.
No dungeon should have unavoidable deathtraps. There should be warnings, hints, signs or the like so that the players have the opportunity to make an educated guess, even if wrong. It shouldn't be there to screw the players but to challenge them.
