Not really... because it tells anyone with a brain exactly where you are (precisely the opposite direction, the direction equal to the distance the spectre has moved in the wrong direction). I think the best solution would be for Spectral Guise to either be a ground-targeted teleport or something, or for it to cast Mind Flay - or both.
unless you use the old shifting puzzle trick... where if you run into a wall... the specter keeps moving.
