Usage: Contortion involves the twisting and bending of limbs and body parts in order to be flexible as well as escaping from traps or being held.
Contortion is typically used as an opposed check against another character or as a check against a DC set by a trap or item.
Squeezing
Contortion can also be used to squeeze through spaces where your head normally wouldn't be able to fit (2 in. for medium creatures), doing so requires a DC 80 check to be made.
