What's most hilarious is that potions have a splash effect when thrown. If you target just right, one can hit four units with a single potion. Of course, the units will need grouped into roughly a ten foot square, but it's doable.
So I find it most hilarious to kill 1HP Findal in the Underground Passage with a thrown Healing Potion. I'm sure the Oathbreakers will be the happiest of all???
