The point is if you and your master are trying to hide your identity, telling people you can ethereally jaunt into the room, and teleport to the room, and that he can command you to then seduce and weaken "with subtle magic" the necromancer laying within, that lays out three clues, that spellcasters and intelligent characters would be sitting there and asking themselves, "ok, so she has mondo power to do these things, but has no offensive capabilities....so what the hell is she?" My only point in laying this out, is that if he's trying to keep your identity secret, he should do his best to be a bit more subtle in his use of you. Maybe claiming he is going to go scout out the locations using secret magics, and then when you're alone in a room, he sends you to do it, and he takes credit. Things of that nature, that take your abilities and remove them from our sight. It may still raise suspicions, but not as much as the way it's being approached at present. Again, not trying to be a dick, actually thought I was tryin to be helpful here.
