Questions about potions.

Yeah, ginseng roots are preferable when you're misting/curtaining due to ales either healing too much or leaving you at dangerously low hp/mp as well as the need to spam hp potions along with mana bulls. When using ultimates, you typically don't get hit all that much (assuming you're not going to skelegons at 120 or something), so mana bulls are preferred with the occasional hp potion when you get hit. You should wait until you have at least 4667mp for any of the %-based potions, unless you want to use roots while misting/curtaining.
