Underdark Encounters
Underdark encounters for creatures encountered in subterranean caverns, lightless tunnels, and the deep wild beneath the surface world. Aberrations dominate the pool; the deeper the party descends, the worse it gets.
Roll the Underdark 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.
