Startling Appearance (Vigilante)
FEAT 6 1 action
You are completely unnoticed by the target creature.
You can startle foes who are unaware of your presence. Make a Strike against your target. That creature is Off-Guard against this Strike, as normal. If your Strike hits, the target remains off-guard for the rest of your turn and is Frightened 1 (frightened 2 on a critical hit).
