Witches will often specialize in trades to make money. There are so many witches in the area, its impossible for them to all sell the same stock without basically giving them away for free. This particular shop is run by the potions specialist in the plains. They've got everything from minor healing potions to endurance enhancers and everything in between. Come in and get what you need, they're excited to sell what they've got! If you would like to be the potions master, pm me and place it in your occupation in your application
