You go into battle with way too little clothes for common sensibilities. This can distract an opponents at critical moments. Once per session, you can declare that any action performed against you simply fails - after knowing the result.
You must be mostly naked to use this. You can wear light armor with, but it must be specially made to accomodate your style. You must not be encumbered. If you are wearing clothes, you can drop them as a 1-shot defensive action in order to activate this schtick.
This does not work on anyone who cannot be shocked by your nudity. This includes anyone immune to Seduction, such as those with Damage Immunity to Life or Influence, as well as Cold Fish.
