TUMBLE (DEX; TRAINED ONLY; ARMOR CHECK PENALTY)
You can’t use this skill if your speed has been reduced by armor, excess equipment, or loot.
Check: You can land softly when you fall or tumble past opponents. You can also tumble to entertain an audience (as though using the Perform skill). The DCs for various tasks involving the Tumble skill are given on the table below.
Tumble 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.
<--quote snipped here-->
Tumbling around someone and failing means you burn double the amount of movement for entering your intended destination square (and you still DO enter it), but you draw an attack of opportunity from any enemy who can and wishes to do so. You may continue to move as normal, drawing AoO as normal.
Tumbling through someone/thing is a little different. If you fail you stop your movement (no more movement for that action) and draw an AoO. If you still have a move action or a standard action left, you may attempt again. Or do something else. Your call.
