Tumble

Tumble is an ability used by members of the Guild of Thieves and the Mummers. The thief will have a passive chance to tumble away from melee attacks. This occurs before other combat calculations (dodge, block, parry) are taken into account, and is essentially an extra chance per attack to avoid getting hit.

In addition, the thief can get improved results from the tumble verb, allowing them to tumble more smoothly and tumble up to a standing position had they been sitting or prone.
