Potter's Portable Protection Potion

**Potter's Portable Protection Potion**, also referred to as just "protection potion", is an area-effect potion invented and developed by Harry Potter.

## Function

The Protection Potion is meant to be poured on the ground in a circle, and will then create a long-lasting (approximately 12-hour) version of the Fortis shield. The circle must be unbroken to take effect. Unlike a shield cast by a wand, it is not dependent on the user's magic; it requires no special skill or concentration, and will endure even if they fall asleep or unconscious. The shield is powerful enough to provide protection against most beasts, even vampires and werewolves, although a skilled or powerful wizard would likely have ways to break it.

## History

Harry created the potion in the summer of 1993 for her internship at the Potions Guild under Potions Master Thompson. After learning his specialty was area-effect potions (specifically Battle Potions), Harry began to think about area-effect potions she could make. She was inspired by the Barrier Button, a Marauder invention which created a remote-controlled barrier around an ordinary-looking button. She had already been able to create potions which had magic shaped like a spell inside of it, which she had previously used to make a Modified Weightless Draught for Draco Malfoy's birthday the year before.

Her idea was initially met with skepticism by Thompson, who had never heard of imbuing shaped magic and didn't think it was "a thing". However, once he witnessed her imbue a Hover Charm into a Weightless Draught to create her Modified Weightless Draught, he realized the technique's potential to change the field of Potions, and he began to actively assist her. Together, they created a base that was almost entirely neutral, with ingredients that balanced each other out to create a mold for whatever magic would be imbued within it. She used her entire internship's allowance in just the first few weeks of experimentation.

Harry ended up developing two different potions for her presentation: the Protection Potion imbued with a Fortis Shield and the antidote imbued with the Lightning Jaw, a ward-disruptor. She demonstrated it to general excitement at the Guild's Open House.

Harry wanted to call it the "Ward-Maker", but Thompson suggested the name "Potter's Portable Protection Potion", believing that it had more "flair". Harry didn't like the full name, but she did adopt the name "Protection Potion" in her head. However, the name "Potter's Portable Protection Potion" continued to be used officially both among the Ministry and in the Serpent's Storeroom, to Harry's annoyance. For her fourteenth birthday, Harry's father James Potter made custom labels for her potion, which read "Potter's Protection Potion".

The Unspeakables at the Department of Mysteries continued to investigate the potions technique and the potion itself(looking into soundproofing the barrier for use against banshees and sirens), though they had trouble replicating the process. With few people able to shaped imbue, Harry herself sold her potion through Edgar Krait and Horace Burke, though she insisted on not patenting it.

Harry also considered making more permanent blood wards with her potion, but Severus Snape discouraged the idea, believing magic of that strength shouldn't be so easily accessible.

## How to Brew

Though the exact recipe is not given, the ingredients are all relatively cheap and balance each other out to become neutral. According to Harry, the base is "one of the most simplest potions in existence", and even a second-year could brew it. However, the imbuing technique is much more advanced and requires strong magical control, meaning few people besides Harry and Snape could do it.
