Tumble (D&D skill)

Unofficial rules compendium

The Tumble skill benefits from the Naked Agility rule.

A character with 5 or more ranks of Tumble skill can decide whether to use accelerated tumbling after making the roll. Anytime you make a Tumble roll by a margin of 5 or more, you can use this option.

If you tumble into someone's space, and you could normally occupy the same space, the difficulty is the same as if you were just tumbling through his reach.

Opposed Tumble (Option)

The DC of tumbling through an opponent's space or reach is 10 + that opponent's Reflex Save modifier. Make a separate roll against each opponent; you do not incur a penalty for tumbling against multiple opponents.

In order to move through an opponent's space and not provoke an attack of opportunity, you must beat the DC by 10 or more; if you succeed but not by a sufficient margin, you provoke an attack of opportunity but can still make the move.
