Demonic Skin

(Fiendish Codex I: Hordes of the Abyss, page 85, DnD 3.5)

[Abyssal Heritor]

Your skin has rough, scaly patches that enhance your natural armor.

Benefit

Your natural armor bonus improves by 1. This improvement increases by 1 for every two Abyssal heritor feats you possess. If you do not have natural armor, assume your natural armor bonus is +0.

Special

Your thickened skin tends to catch on objects and makes you less flexible. Because of these effects, you take a -2 penalty on Escape Artist checks.
