I have just had it pointed out to me that it couldnt have been a mystic and prophet as they cannot shatter potions you are holding in your hand.
Apparantly only sorcerers and bards can do it...
Therefore it must have been a bard.
Please re-read post 1395 and put the word bard where it says mystic and prophet.
Thanks
