Tumbling

By using your Acrobatics skill, you may move past those threatening with attacks of opportunity by tumbling. Consult the chart below for the required check roll, and the task to achieve. This task roll may be increased by the threatening attacker's proficiency bonus or DEX bonus at the GM's discretion.

Athletics Check DC	Task
15	Treat a fall as if it were 10 feet shorter than it really is when determining damage.
15	Tumble at one-half speed as part of normal movement, provoking no attacks of opportunity while doing so. Failure means you provoke attacks of opportunity normally. Check separately for each opponent you move past, in the order in which you pass them (player’s choice of order in case of a tie). Each additional enemy after the first adds +2 to the Tumble DC.
25	Tumble at one-half speed through an area occupied by an enemy (over, under, or around the opponent) as part of normal movement, provoking no attacks of opportunity while doing so. Failure means you stop before entering the enemy-occupied area and provoke an attack of opportunity from that enemy. Check separately for each opponent. Each additional enemy after the first adds +2 to the Tumble DC.

Accelerated Tumbling: You may try to tumble past or through enemies more quickly than normal. By accepting a -10 penalty on your Tumble checks, you can move at your full speed instead of one-half your speed.
