Acrobatics measures your ability to perform tasks requiring coordination and grace. When you use the Escape basic action, you can use your Acrobatics modifier instead of your unarmed attack modifier. You can also use it for the basic actions Arrest a Fall and Grab an Edge instead of Reflex.
You move across a narrow surface or uneven ground, attempting an Acrobatics check against its Balance DC. You are off-guard while on a narrow surface or uneven ground.
You Stride up to your Speed. During this movement, you can try to move through the space of one enemy. Attempt an Acrobatics check against the enemy's Reflex DC as soon as you try to enter its space. You can Tumble Through using Climb, Fly, Swim, or another action instead of Stride in the appropriate environment.
You try a difficult maneuver while flying. Attempt an Acrobatics check. The GM determines what maneuvers are possible, but they rarely allow you to move farther than your fly Speed.
You contort yourself to squeeze through a space so small you can barely fit through. This action is for exceptionally small spaces; many tight spaces are difficult terrain that you can move through more quickly and without a check.
You're an incredible acrobat, evoking wonder and enrapturing audiences with your prowess. It's almost a performance! You can roll an Acrobatics check instead of a Performance check when using the Perform action.
Your catlike aerial acrobatics allow you to cushion your falls. Treat falls as 10 feet shorter. If you're an expert in Acrobatics, treat falls as 25 feet shorter. If you're a master in Acrobatics, treat them as 50 feet shorter. If you're legendary in Acrobatics, you always land on your feet and don't take damage, regardless of the distance of the fall.
You Squeeze 5 feet per round (10 feet on a critical success). If you're legendary in Acrobatics, you Squeeze at full Speed.
You can keep your balance easily, even in adverse conditions. Whenever you roll a success using the Balance action, you get a critical success instead. You're not "flat-footed" while attempting to Balance on narrow surfaces and uneven ground. Thanks to your incredible balance, you can attempt an Acrobatics check instead of a Reflex save to Grab an Edge.
You can Crawl incredibly swiftly—up to half your Speed, rather than 5 feet. If you're a master in Acrobatics, you can Crawl at full Speed, and if you're legendary, you aren't "flat-footed" while "prone".
You move with grace in flight and can perform amazing aerial stunts. You gain a +2 circumstance bonus to Acrobatics checks to Maneuver in Flight and can combine two maneuvers into a single action, such as reversing direction while making a steep ascent or descent or hovering in gale-force winds. The DC of the Acrobatics check is equal to the DC of the most difficult maneuver + 5. If you're legendary in Acrobatics, you can combine three such maneuvers into a single action; the DC of the Acrobatics check is equal to the DC of the most difficult maneuver + 10. Regardless of the combination, these maneuvers rarely allow you to move farther than your fly Speed.
You stand up. This movement doesn't trigger reactions.
