In Harry Potter as Neville Longbottom

"Boom!" Crashing on a wall, Neville fell down like a broken dummy. He felt like a truck had rammed on his chest. To be honest, this was the toughest attack on his body till now. If he was a sleek or thin guy, his bones would have been crushed just by the impact alone.

"AAAH!" Groaning painfully, Neville tried to get up, but he failed and fell down on the floor again. He tried to take deep breaths to maintain his sanity and applied Occlumency to block all emotions affecting him.

He needed to have a clear head if he wants to cure himself.

"FUCK!!" Cursing himself for such a blatant show of stupidity, Nev somehow managed to grab the chair in the study room and dragged himself up.

Neville knew he was in big trouble. His body was injured in multiple places. His head was bleeding and every time, he would try to breathe, his chest will hurt.

"Where is my wand!?" Neville tried to focus on his wand, but he couldn't remember where it fell after he hit the wall. He cast the spell - The Summoning Charm (Accio) nonverbally and focused on his wand and it flew directly into his open hands from one corner of the room.

He applied the healing charm he knew but healing charms were not something he ever practised or even learned properly. So the best he could do was fix his broken ribs and stop the bleeding from his head.

However just as he managed to fix his head, the jinx started to run a rampage inside his magical reserve. The pain was immense, and he immediately lost all his strength and fell down on his knees hugging his chest tightly.

"Winny?" He shouted with all his strength.

"Yes, Master?" Winny apparated directly inside the study room and found the horrific situation of her master who was hurt and bleeding.

"Master, Master…wait..." Winny panicked for a few seconds before using her magic to stop the jinx from spreading inside his body.

Neville finally felt some relief and he gestured for Winny to come closer to him.

"Potions room. Now!" He could only say these few sentences before Winny apparated with him directly inside the potions room.

With a stuffed chest and heavy breathing, Neville was brought to the potions room by Winny and his body was unable to handle this space travel making him cough up more blood. Neville felt very uncomfortable at apparition this time and found that the jinx was reacting to magic.

Every time magic was used on him or by him, the Jinx became more powerful. The jinx was attacking his magical flow and was spreading inside his body like a fucking plague. This was purposely created to attack a wizard and make him/her unable to use magic to heal themselves resulting in a slow painful death.

Imagine the effect on a young child like Ginny. The physical attack in itself would have disabled her or killed her and if somehow, she survived, she could not use her own magic to save herself.

Neville never considered this world to be a story world meant for kids but even he never thought Malfoys would fall that low. Neville was unable to stand properly so Winny put him on the floor gently.

In the potions room, Winny grabbed a bottle of Dittany juice, Bruise removal paste and others (whose labels she could barely read) and applied them directly to his master's chest area.

After finding the pain minimised a lot in his chest area, Neville opened his eyes and found the two big puppy eyes crying while helping him.

"Ssshh…" Stop crying, Winny. This is a nasty jinx. More of a dark magic type. The healing potions won't work for long on this.

We need to make something specifically for this. I am going to give you some ideas you think which one makes sense.

If we use the blood from Diana as the base to burn or purify the jinx, put some unicorn horn powder to add more purifying abilities and Flobberworm Mucus to thicken the paste, will that work?"

Winny somehow forced her small house-elf brain to run faster and faster and tried to think hard on all the potion materials she came in contact with recently.

"Master, we must add juices from Moondrew flowers otherwise the potion will not work. It will reduce the pain master and help you heal faster. Plus to heal the physical wound, we must add Dittany juice." Winny replied while trying to find the necessary ingredients.

One after another, she used magic to bring all the potion materials and then lit the cauldron. First went the Moondrew flowers' juice, then some Flobberworm Mucus. After the potion was thickened to a certain extent, she threw down, Dittany juice and kept stirring to mix everything perfectly.

Looking at the performance of his house-elf, Neville felt how can anyone torture such creatures. If you love them, they love you 100 times back. Besides, he never knew Winny could think of potion materials on her own. He was already thinking of going to St. Mungo's for this. He knew his Nan will not make it easy afterwards, but he felt only St. Mungo's will have someone expert in such a potion.

Now, he found after making cauldron after cauldron of potions, Winny herself had become somehow an expert in this.

Thinking these thoughts, he used all his willpower to not focus on the pain in his body and look carefully at this Elf. The mind must be distracted and focused to avoid losing consciousness at the key time.

"Master…Master check now, master?" Winny suddenly ran towards him after grabbing the vial of freshly made potion. It took her no less than a half-hour, but she did manage to concoct this thing.

A potion made with the blood of Dragon, the powdered horn of Unicorn, Dittany and Moondrew flower juices plus some Flobberworm Mucus. This has to be an original recipe as no one was rich enough or brave enough to hurt a dragon and used its blood in a potion.

After shaking the potion thoroughly, he opened the cork and took a whisp of a very faint scent that bought him great relief inside his chest and calmed down the throbbing pain in his head. This blood-red potion was surely the best possible Healing Potion anyone can think of after being attacked by the Dark Magic.

Grabbing the vial, he used a dropper to put a single drop inside his mouth and then another and then another. It was just after the third drop, that the uneasiness inside his body disappeared.

"Amazing. It works! HA HA HA…. Laughing in joy Neville forgot the pain in his body before his laughter was cut short by the spike in the pain from his chest area. That was surely from a broken rib.

The jinx was gone but the physical damage was still there.

"I guess I need to sleep this off otherwise the chest will hurt if I move too much."

Thinking this, Neville

"Winny, two things…

First, collect this potion in different vials and store them safely. Also, write down the entire process. The ingredients and their importance. Don't miss a single detail. This is the first healing potion we have made and If I am going to sell it, I must first get a Ministry Proof of this potion belonging to us, the Longbottoms.

Second, bring my lunch inside my room. I am going to take an afternoon nap.

Finally, not a single word to Nan. Okay. She is already old, and you don't want to hurt the old mistress. Right?"

Using an overly loyal House-elf, Neville managed to keep this jinx incident under wraps. He apparated inside his room and looked back in the mirror. His body was back to normal with no signs of any attack.
