Description: You can keep your balance while traversing narrow or treacherous surfaces. You can also dive, f lip, jump, and roll to avoid attacks and overcome obstacles.
Check: You can use Acrobatics to move on narrow surfaces and uneven ground without falling. A successful check allows you to move at half speed across such surfaces—only one check is needed per round.If you take damage while using Acrobatics, you must immediately make another Acrobatics check at the same DC to avoid falling or being knocked prone.
In addition, you can move through a threatened square without provoking an attack of opportunity from an enemy by using Acrobatics. When moving in this way,you move at half speed. You can move at full speed by increasing the DC of the check by 10. You cannot use Acrobatics to move past foes if your speed is reduced due to carrying a medium or heavy load.
Finally, you can use the Acrobatics skill to make jumps or to soften a fall. The base DC to make a jump is equal to the distance to be crossed (if horizontal) or four times the height to be reached (if vertical). These DCs double if you do not have at least 10 feet of space to get a running start. The only Acrobatics modifiers that apply are those concerning the surface you are jumping from. If you fail this check by 4 or less, you can attempt a DC 20 Ref lex save to grab hold of the other side after having missed the jump. If you fail by 5 or more, you fail to make the jump and fall (or land prone, in the case of a vertical jump).
Action: None. An Acrobatics check is made as part of another action or as a reaction to a situation.
Special: If you have 3 or more ranks in Acrobatics, you gain a +3 dodge bonus to AC when fighting defensively instead of the usual +2, and a +6 dodge bonus to AC when taking the total defense action instead of the usual +4.
