Vexing Dodger

When adjacent to or in the space of a corporeal creature at least one size category larger than herself, a vexing dodger can climb that creature's body with a successful Climb check against a DC equal to the target creature's CMD. Although the vexing dodger is holding on to the creature, this action isn't a grapple; it doesn't provoke attacks of opportunity from the creature, and neither the vexing dodger nor the creature she climbs gains the grappled condition. While the vexing dodger is on the climbed creature, the creature takes a penalty on attack rolls against the vexing dodger equal to the number of sneak attack dice the dodger possesses.

This ability replaces trapfinding.

At 2nd level, a vexing dodger gains Improved Dirty Trick as a bonus feat, even if she doesn't meet the prerequisites.

This ability replaces the rogue talent gained at 2nd level.

At 3rd level, a vexing dodger gains a +1 morale bonus on Acrobatics, Climb, and Escape Artist attempts against creatures at least one size category larger than herself. This bonus increases by 1 for every 3 levels beyond 3rd.

This ability replaces trap sense.

At 4th level, a vexing dodger can move through the space of a creature two size categories larger than herself without needing to attempt an Acrobatics check. She would still need to succeed at Acrobatics checks to avoid attacks of opportunity provoked by leaving a threatened space; this ability covers only the ability to move. Additionally, whenever the vexing dodger hits a larger foe with a melee sneak attack, she can choose to forgo the sneak attack bonus damage and instead attempt make a dirty trick combat maneuver as a swift action.

This ability replaces uncanny dodge.

At 8th level, when a vexing dodger attempts a dirty trick maneuver against a creature she's climbing, she gets a bonus on the combat maneuver check equal to the number of sneak attack dice she has.

If she chooses to sicken the target with her dirty trick and succeeds at her combat maneuver check, the target must succeed at a Fortitude saving throw (DC = 10 + 1/2 the vexing dodger's level + her Intelligence modifier) or be nauseated for 1 round.

This ability replaces improved uncanny dodge.
