Defensive Roll (Ex)

Starting at 5th level, once per day, a shadowdancer can attempt to avoid a lethal blow. This functions as the rogue’s advanced talent of the same name.

Improved Uncanny Dodge (Ex): At 5th level and higher, shadowdancer can no longer be flanked. This defense denies a rogue the ability to sneak attack the shadowdancer by flanking her, unless the attacker has at least four more rogue levels than the target has shadowdancer levels.

If a character already has uncanny dodge from another class, the levels from the classes that grant uncanny dodge stack to determine the minimum rogue level required to flank the character.
