Algernon's Enhancement

This spell can only be performed by 1 hour ritual or as a potion.  When cast on a living creature with a CR not greater then the spell caster's level, raises that creatures intelligence by 3d4 (max 20) for 2d12 days.  After that time the creature's intelligence fades by 1 point per day until it is back to its original level.  If the creature is a domestic animal it can speak one language with which it has become familiar hearing.  A humanoid may suddenly learn an additional language in the same manner.

NOTE, ONCE THE CREATURE HAS RETURNED TO NORMAL, ANY FURTHER ATTEMPTS TO CAST THIS SPELL UPON IT AGAIN WILL FAIL.
