Table Rolls - 5E Underwater Encounters

"In a depression in amongst the dead coral lie a dozen ogre-like creatures with fins. One keeps watch while it's exhausted companions rest." Why are these creatures fatigued?

Generated from the Underwater Locations (roll of 13) and Underwater Levels 11+ (roll of 5) tables below. Enhanced from an Encounter Activity/State table from a previous article (roll of 16).

Underwater Encounters

Encounters underwater bring visions of murky seas, vast reefs and dark depths. They might occur in a kelp bed, an underwater cave or by a long-forgotten shipwreck.

A totally different place to the surface, it is dominated by maelstroms and currents with vast tracks of open water. It is home to and reptilian sea races, tentacles beasts and primordial ancients
