Concoction of Ifrinn's Bile
As a result of my exhaustive trials with many subjects, I have found a solution with the most preferred of outcomes. Many of these ingredients are harmful alone, but work together to numb the subject of pain, and increase feral tendencies along with an uplift in all physical aspects. But this solution can produce an end product of varying potencies, depending on the order in which they are mixed. I have deduced that there are four very potent mixing orders to create the most effective serum. Since the gate to my apothecary will only open to a certain potency at any given time, I have devised a way to help me remember which mixing order is correct. The braziers hanging from each door in this room will signify a solution. All I have to remember is which order corresponds with which brazier. Ingenious.
Of the varying mixing potencies I have discovered, the gate will accept any of the following orders.
