Description

It gains resistance 5 against a single energy type (acid, cold, electricity, or fire).
It gains an additional natural attack (bite, tentacle, etc.) with damage appropriate to its size.
Its slam damage type changes to slashing or piercing.
Its slam damage die increases by one step (from 1d6 to 1d8 for most brethedans).
It gains a +4 natural armor bonus to AC.
Its reach increases to 20 feet.

A brethedan can only have one modification in effect at any one time—if it selects a new adaptation, it loses any other in effect. More extreme adaptations are also possible (at the GM's discretion), but generally take days or even months to adopt.
