Underwater Non-Combat, NPCs & Hazards
Merfolk, talking crabs and water spirits await in the depths. Young merfolk might be curious about the world beyond the sea or a sea priest might be leading an underwater ritual. Meet NPCs from a berserker who has fallen in love with a sea creature to a merrow with a pipe of bubbles and gifts to hand out. Deal with inky clouds, inquisitive seahorses and strong underwater currents.
There is a 5e Underwater random encounter generator at ChaosGen. There is also a pdf of these and more tables at the DM's Guild as Underwater Encounters.
