I'm looking for a way to make a non-magical item appear to be magical, or a magical item to appear to be something it's not. I know Magic Aura will do this, but only until some low-level MU does an Identify on it, at which point it comes down to a Will save. What I'd like is something a higher-level MU could use that could have a reasonable chance of fooling experienced spellcasters. Any ideas?
