City Cistern [40x40] [4K] [jpg/webp] (Patreon)

The Old Town was always the mirror of the city's prosperous development. Beyond the grins of the shopkeeps, under the shiny floorboard of the embassy, beneath the cobbled streets stirred something ancient, primeval. Few knew that the district was built on the ruins of a much older settlement of unknown origin. There, in the labyrinthine succession of collapsed tunnels and dry aqueducts, something primordial stirred, occasionally leaving its dark chambers for brief visits to the numerous sewers and cisterns that were connected to its lair, much to the dismay of the city workers.

The stage is set: This map was made with a large creature in mind, like a Hydra or Beholder. Climbing or Flying speeds would make for interesting challenges. The party is tasked to battle the monster in a very tight arena. Falling doesn't mean death as water will soften their fall. However, with no solid ground in sight, characters who are unable to climb on wet walls will have a difficult underwater combat ahead of them.

Filthy Waters: The sewage is no ordinary place to fight. A character that falls in must succeed on a DC 16 Constitution saving throw or gains a random sickness from the water. The effects will worsen with time (if they survive).

Additional challenges: If you thought that poisonous water made things too easy, the acid, lava and giant maw variations will make falling much more lethal. Acid will deal 3d6 acid damage at the start of a creature's turn. Lava will deal 3d10 fire damage. The maw will deal 4d6 piercing damage on a failed DC 17 Dexterity saving throw, or only half on a success.
