Trojan Hippogriff

You may make anyone you see look as if the they not have any armor on, do not have any weapons and hide their arcane auras to appear non magical; including yourself. When you cast this all who are effected succeed all charisma saving throws and get surprise attacks. Your gear is visible the next time they are hit with any attack. 

If you use this on an opponent they must pass a DC 17 perception check to find their weapon, spell book, arcane focus or firearm. Out of combat you may automatic pass a deception check to make them think they have lost their item.
