A way to make pure bloods into pets.

Rule 1. The weakest muggleborn student at Hogwarts is stronger than the strongest pure blooded student or graduate. They can prevent any magic from effecting them and all know a spell which can prevent any pureblooded student or graduate of their choice around them from casting any magic until they are given permission to use magic again.

Rule 2. A muggleborn student can anoint another student or graduate of Hogwarts as an honorary muggleborn granting them all the same benefits a muggleborn has.

Rule 3. All muggleborn students can freely control the size and shape of their bodies. They can add extra limbs or other such appendages, make themselves into giants, change species, or change genders. They can also change back to their default form whenever they want.

Rule 4. If a muggleborn grabs hold of a pure blood or a person who believes in blood supremacy they can freely alter their size and shape as well. Forcibly applying any of the kinds of changes on them they can apply to themselves. These changes are permanent once applied unless another muggleborn changes them back.

Rule 5. All pure bloods and people who believe in blood supremacy are sexually submissive and massive sluts. They will come easily if any kind of sexual stimulation is applied to them and will freely surrender to their partners and allow them to do whatever they want to them in exchange for more pleasure and sexual satisfaction. They are especially weak to any kind of sexual advances from muggleborns and will offer no resistance if a muggleborn attempts to overpower them and **** them.

Rule 6. A muggleborn's sexual fluids are addicting to purebloods and people who believe in blood supremacy. Once exposed to them a person will become extremely aroused by the thought of the muggleborn. They will long to be sexually dominated by them and will be drawn to them. The more a pure blood or a person who believes in blood supremacy is exposed to a muggleborn's sexual fluids the more powerful this addiction will grow. Eventually they will be willing to agree to do anything if it means having sex with a muggleborn again. They will even be willing to become the pets and property of a muggleborn, giving up all their rights and swearing on magical oath to obey the muggleborn for the rest of their lives.

Rule 7. Pure bloods and people who believe in blood supremacy are highly embarrassed of their sexual weakness. They will do their best to hide any sexual encounter they have with a muggleborn and will even keep it secret if they are taken by ****.

Rule 8. Muggleborns can always tell if a person is a pure blood or if they believe in blood supremacy and know spells that will allow them to track down any such person that they wish to find. They also know how to get past any barrier that stands in the way of them reaching a person they want to find.

There now she had the means of bringing down anyone who supported the so-called dark lord and bringing them over to the right side of this conflict. As well as a new way to have some fun herself. She was especially proud of her rule that allowed her to pass on all the benefits of her rules to people of her choice. That way she could keep the people she cared about safe. This was going to be a perfect plan.

Once she was finished writing she placed the rule book in her bag and then stretched her arms. She felt something snap beneath her robes. She quickly pulled them off and realized her bra and panties had broken and fallen off her body.

As she looked down on herself she found her body had undergone a radical transformation. Her arms, legs and abs were now covered in bulging muscles. She stood much taller than she had before. It seemed her body had moved all her excess fat to her chest and hips where it wouldn’t get in her way. She was utterly dumbstruck by what she was seeing.

Apparently, there were some pure bloods out there that kept themselves in excellent shape, because it seemed her first rule had turned her into a veritable amazon to surpass them. She had been thinking of magical strength not physical strength when she wrote that rule but this definitely worked too. She picked up her wand and flicked it about experimentally. When she did a nearly overwhelming sense of power flowed through her in response. So her rule was working as intended. It had just had a few other effects as well. That was fine, this felt amazing after all.

Her first thought had been to head back to Gryffindor tower to anoint Harry and Ron as honorary muggleborns and share this power with them. Then they could start plotting how to take the Slytherins down before moving on to Voldemort and his **** eaters. But with this heady sense of power filling her she was tempted to strike the first blow herself.

She cast her new locating charm to check and see if she had any targets of opportunity to work with. Sure enough when she cast it for Draco Malfoy she found him all alone up in the room of requirement. And now she could think of several ways to break into that room and reach him while he was all alone. This offered her some interesting new temptations.
