i got a potion of flying from the underdark wizards tower with the clockwork guy at the top, he gave it to me after i read a line from one of the books i found in the tower. tried using it, but it seems to have no effect, and or i cant find a button to enable flight. so far just seems to be a long lasting feather fall. really disappointing was gonna use it to explore and or retrieve that gem in the underdark temple of selune.
