For the section on poisons you can make with Minor Creation, I know there's an online source (official) that has a poison with a DC of 26, plant based, does 2d6 con/2d6 con. It's great for when Black Lotus won't land due to save issues. Unfortunately, I can't remember which online suppliment it is, though I know it's sold by a guy in one of the lower planes, for what that's worth.
