I've just completed the White Phial quest - and I've got to the bit where you choose what to fill the Phial with a particular type of potion... but I'm not entirely sure which. My main skill focuses are Archery, Destructive Magic and Double Handed... So I could go for a specific job - however, simply HP restoration seems pretty neat... but something more specific could be beneficial as well... what did you choose, and what would you suggest?
