Underwater Encounters
Underwater encounters for creatures encountered submerged in oceans, lakes, rivers, or flooded passages. The pool is intentionally narrow — only creatures that can plausibly fight, breed, or hunt while submerged appear here.
Roll the Underwater Type Table first, then the matching creature table below.
Some results on the Special creature table route to the matching subtable for the specific creature.
See Type Tables for the wilderness terrain and other distinct environments.
