Would it be possible to implement ESP potions, similar to detect invisible potions?  Like, you'd have ESP for a limited time.  I just think it'd be nice since ESP is so in demand but not that easy to find, and then one could get it  at lower levels too.  Maybe the BM could carry them or something?

ESP is one of the game limiters.  It's intentionally rare hand hard to find.  Poison resistance (in a useful form) is another.  Niether of these items should be readily available.
