Mary resisted the urge to try the vials out right away when there was more to learn. She'd always been a dutiful student when she was still in school. To this day she enjoyed spending her time reading manuals for her new toys and tools before she put them to use. So she closed the drawer and folded up the instructions. Her finger pressed the button on top of the box, eliciting a slight chunking noise and a drawer popped open with nine empty slots.
Curious, Mary ran her fingers over the shallow depressions, feeling the cool wood-grain of the drawer. With no response she unfolded the piece of paper, which once more had a new header and new information.
"This is the Precision Mixology drawer.
While simple mixing is possible in any vessel or by simply ingesting small amounts from multiple vials simultaneously, this drawer allows for more specific mixing and matching of traits from vials. Precisely target body parts, traits, behavioral patterns, or even metaphysical qualities. Simply gather up to nine vials from the other drawers and place them in slots within the tray. As you do so, focus and think hard on the specific qualities you wish to combine.
Then close the box and wait a few seconds. When the Drawer reopens we will have returned all vials to their original homes and created a single remaining vial with all combined traits and details. Drink this vial and be sure to return it to the tray to avoid excessive waste. Your new precision mixed vial will be able to create changes that will astound you, even if you are an experienced user of the Magic Vials System.
As an example, a long-time user of the Magic Vials System complained that they wished to take on a form inspired by a snake, commonly called a naga. But they were infatuated with "knotting", and wanted to keep a canine penis. Numerous attempts to mix snake, human, and various canine vials failed to give the results they wanted but with the introduction of the Precision Mixology System their desired form was only moments away!
However, it behooves us to provide a few extra warnings. As powerful and flexible as this system is, it is also dangerous. Several users, eager to experiment, rendered themselves non-sentient, immobile, or simply suffocated beneath their own changes. While a human vial can return you to a relatively normal human form, you must still be able to drink it to change back. Additionally, we do not recommend placing non-provided liquids (bodily fluids, water, fruit juice, etc.) in the Precision Mixing tray. We do not certify or guarantee any results that may occur from such unorthodox attempts.
This page completes your introductory materials to the Magic Vials System. We hope you enjoy your time to come and should you ever wish to review these instructions, you can always find them by picturing a piece of paper when you open the Miscellaneous Drawer. Happy Vialing!"
Mary turned the page over to the blank back, just to make sure. "Huh." She said. "It seems..." She trailed off, voice filling the empty living room of her one bedroom apartment, "...impossible?" She pushed the drawer closed, and drummed her fingers on the top. If it was a prank, it was an elaborate one, and one she couldn't figure out how to duplicate. The changing paper alone seemed magical. "I guess," Mary said, "There's only one way to know." She would have to try the vials, on some living thing. She'd be easiest but the warnings from the sheet made her a little scared.
After a few minutes of considering her options, Mary at last decided...
