Rincewind the Inebriated Wizard

As Rincewind did brew his potions, he becameth confused, and mixed items of strange properties.  Quaffing it upon accident he did become inebriated, unable to control his mystic might.  Now, his powers, and even his sense of direction, change at uncontrollable, irregular intervals.  His only hope, the legendary Potion of Massive Sobriety, within the Caverns of Flaming Doom.  But beware, at each step his inebriation changes and his powers shift (watch the beaker to see when these changes will happen).  If the beaker fills completely he is done for.  Destroy all cauldrons to unlock the portal to the next level.
