I did a spell that keeps people out of my room, however it does so by producing a rather disgusting smell with no disernable origin (I can only make it smell nicer for a few moments at my skill level, and even if I could full time, it probably would render the spell worthless). Anyone have any suggestions on how to keep people out of my room without it smelling horrible? I could probably make people ignore it, but that's really hard and I can only do that for a few seconds at present and I've never tried with anything as large as a room before.

Any suggestions are appriciated.
