You can squeeze out of tight situations by twisting and bending your body into unnatural positions, gaining an advantage against foes that try to pin you down. You gain the Quick Squeeze skill feat, and if you're a master in Acrobatics, you can Squeeze at full Speed. Whenever you successfully Escape using Acrobatics, the creature you Escaped from is off-guard against the next attack you make against it before the end of your next turn.
