Requires Combat Advantage

An FX with this flaw is a surprise attack, which requires you to have Combat Advantage against a target before using the FX. This generally applies to an FX that is usable against others, since you can only use it against a foe who is more vulnerable than normal. If you do not gain combat advantage, you cannot use the FX.
