So if the septer thing works it could be a bit more discreet like a cane maybe. but yah. i was thinking for effects maybe he could be sending out magic illusions making you think your seeing something your not. Like butterflies or doves flying at you or something.
if the septer isnt what you want he could be doing the same thing only just with his hand. The last pose is kinda like a jedi move " you won't remember my presence. you've never seen me before" and i could put in some "invisible" effect. lol! yah anywhos.
