Slippery Skin

(Exemplars of Evil, page 26, DnD 3.5)

[General]

You can expertly avoid the grasp of your enemies.

Prerequisite

Combat Reflexes, Escape Artist 9 ranks

Benefit

If a creature makes a touch attack against you to initiate a grapple, you can sacrifice one of your attacks of opportunity as an immediate action to make an Escape Artist check. You must use the check result in place of your touch Armor Class, even if the result is lower.
