Deep Dweller

Various Sized 

Source(s):	Monsternomicon 1
Alignment:	Same as base creature
Challenge Rating:	+1 (template creature)
This is a creature that has adjusted to a subterranean environment. Often times they are lone creatures that wandered into such an environment and adapted. This template is typically not applied to Large or larger creatures, and obviously it does not apply to creatures that were already subterranean.
