I think what he's saying is "don't drop too many clues".<br/><br/>You said she can go ethereal. Now casters be all, "Whoa, that's some really powerful magic! She must be a high-level mage!"<br/>Then teleporting without error: "Wow, holy crap, both at once? Super-high-level sorceress!"<br/><br/>Then comes the reality check--if she's so powerful, why is she so limited in what she can do? (As in, why can't she take care of this entire thing solo?)<br/>Then comes the confusion and the checking. What in the universe can go ethereal AND teleport? Lots of outsiders. Probably a bunch of Good ones too.<br/><br/>I'm not saying it's a dead give-away, but it can lead to some uncomfortable questions from people who know better.
