SUB-DERMAL ARMOR |Ex

Gene Pool -5 | Disguise DC Modifier +5

You developed armor plates under your skin due to your mutation which help protect you from taking damage.  You gain DR 1/- from your sub-dermal armor plates. This mutation may be combined with the exoskeleton mutation and other mutations that grant natural armor.  In addition, this DR stacks with any other form of DR, including those provided by armor, items, or feats, but does not stack with cybernetic dermal plating.

Evolution I:  The protection provided by your mutation increases to DR 3/-. 

Evolution II: The protection provided by your mutation increases to DR 5/-.
