Well I'm actually a math freak, it's just the bolded part that confused me. Thanks for the clarification. : All in all whatever setup you choose and whatever inventory you bring, it would be wise to keep around an extra stack maybe 8-10m for either buying or makiing your potions, and maybe in the worst case scenario, replace lost items. You'll find it almost necessary to use saradomin brews and super restores, and don't forget these two items along with the ingredients for it are highly targeted by merchanting clans.
