Narrow Frame (Feat)
Your excellent coordination allows you to maneuver better in close quarters.
Prerequisites: Level 1, Escape Artist 1 rank
Benefit: You do not take penalties on your attack rolls or to your AC for squeezing through a narrow space that is at least half as wide as your normal space (i.e. one size category smaller than your normal size), though each move into or through a narrow space still counts as difficult terrain.
Special: You can also squeeze with an ally in the same space as your own without suffering a penalty to attack rolls or AC (though your ally might suffer them, unless they also have this feat).
Normal: You take a -4 penalty on attack rolls and a -4 penalty to AC while squeezing.
