Puff Torso
(Serpent Kingdoms, page 147, DnD 3.5)
[Monster]
You can puff out your skin to appear larger and more threatening.
Prerequisite
Serpent or serpentfolk
Benefit
As a move action, you can dilate the skin along your torso in the manner of a puff adder. While your body is thus distended, you gain a +4 bonus on Intimidate checks. You can reduce your body back to its normal size as a free action.
