The community responded and below you will find ideas in unedited form. If I missed anyone I do apologize. The fun thing about this little experiment
is the sheer variety that came from it. Keep in mind that on Twitter you are limited to 140 characters. So if you would like to add more material or use our little sunken ziggurat by all means please do. Just remember danger is everywhere so you may want
to bring a few torch bearers and a 10’ pole!
@FailedGM: The cistern holds a hungry narwhal.
@Dungeon_Junk: You find a well-decorated room full of
shelves containing valuable scrolls. They are all ruined due to the damp.
@Dungeon_Junk: In the armoury you discovered the legendary scimitar
Godsbane. It's turned almost completely to rust.
@theAdjunctDM as the party enters the sanctuary, their
torchlight reveals a portion of a massive, golden statue of a Yuan-Ti.
@theAngryGm The Sunken Antechamber: Swamp water fills this
chamber to the knee. Most don't see the stairs under the water... Until they
fall.
@seanbonney: Low ceiling honeycombed with overhead shafts.
Most filled with trip-wire released bones and armor. A few with skeleton
warriors.
@fiddleback: The Room of Hours. Upon entering this large
sand filled room (difficult terrain), PCs are under the influence of a slow
spell.
@jencilmonkey Huge clockwork gears grind inexorably,
partially submerged in the sand, skeletons impaled on the cogs' sharpened teeth
@dmdandanfieldng The floor in the hall is under 6cm of water
mixed with oil from a ruptured flame trap. Any spark will ignite the oil
@karakdamnaz You find a fountain spraying a rainbow hued
liquid. Non-lawful PCs that drink heal 3d8+5 hit points.
@karakdamnaz A sloping room with deep water at the far end blocking exit.
Dessicated frogs litter the floor. The water is an illusion, DC 28.
@medicmsh The vines coil & twine towards the light
far overhead. Their carnivorous rootlets, however, coil & twine towards the
nearest PC...
@bengrunzel The submerged gear room can drain water in one
level, but a hydra-troll is stuck in the gears.
@spaceseeker19 Room
with doors on 6 sides rotates forward each time it's entered, changing its
location & dropping PCs to far wall.
@haelyn78 u find an
altar of an ancient deity. Sacrifice an uncommon magic item gives u adv in the
next 5 checks to locate traps/doors
@Aetherium83 Hall of
Ancestors. A long passage w/ countless lines and symbols etched in blood
identifying the lineages of the tribes.
@ThemDave carapaced
bugs scuttle down a southern hallway using ceilings as floor. Perhaps they lead
to water, perhaps they flee in terror.
@galev_ph The hallway
gets more and more thickly covered in sticky webs towards the end.
@Iron_Fox off of the main foyer is an incongruous ball pit.
