I'm playing Druid at Hogwarts

The method of making blood-stained playing cards is not very difficult. The playing cards are soaked in a potion mixed with the blood of ten types of criminals.

After absorbing the blood and medicine, the cards will become low-level magic materials. Every once in a while, you need to take out the cards and use blood to outline the magic pattern on the cards, and then continue to soak them.

If there had been no failure, it would have taken at least six days to complete the Bloody Solitaire. Teacher Bojin had some conscience and gave him an extra day.

It's just that the blood-stained cards test the basics and require the completion of ten different magic patterns. It is estimated that Teacher Bojin gave Allen an extra day to give Allen a chance to redeem himself.

Allen looked at the materials on the table and thought about which magic spell to use. To be honest, it was easy for Allen to use ten kinds of black magic, but ten kinds of magic patterns were a bit troublesome.

Moreover, Allen is not familiar with the magic patterns of black magic. He needs to practice it at least a dozen times, and he might not have enough time in the end.

At this time, Allen's eyes lit up. In this case, it would be better to replace the blood-stained cards with a field he is familiar with. It is very likely to be completed within seven days.

Allen searched through his memories and finally locked on the healing magic of the Book of Merlin.

In fact, Hufflepuff's inherited food magic and counter-spell magic would be better, and Allen is most familiar with them, but the two magics are not suitable for use on blood-stained cards.

So Alan decided to use healing magic. Alan didn't know how many times he read the Book of Merlin, and he remembered it deeply.

And there are exactly a dozen kinds of healing magic, such as simple healing, swelling dissipation, etc., medium difficulty restoration of eyesight, quick healing of broken bones, separation of toxins, etc., and only one high difficulty, strong healing with life.

Allen has not mastered the ability to heal with life, and has not even reached the threshold. To put it simply, it means exchanging lifespan for quick recovery.

The ability to invoke lifespan is not something that Allen can use at his current level, so Allen has not learned the strong healing spell for the time being.

The amount of magic was done, and Allen looked at the remaining materials, the blood of ten types of criminals. This material was not suitable for healing magic.

"I wonder if using my blood will work."

Allen touched his chin. He was a Druid, his body was full of vitality, his magic attributes were endless, and his blood should also carry vitality.

Moreover, Allen's blood is most suitable for healing magic. The more I think about it, the more feasible this idea becomes.

So Allen began to try, first putting a large tube of blood, and then putting the cards in to soak.

This kind of playing cards is special and will not deform when soaked in liquid.

In his spare time, Allen did not dare to relax. He took out a piece of paper and practiced the magic patterns of healing magic. In order not to waste materials, it was best to practice until he succeeded once.

Ten hours later, Allen picked up one of the cards with a wooden clamp. There was not a drop of blood left on the card, but the color seemed to have some redness.

Allen knew that this was a sign of success, so he would draw a magic pattern on the card and then put it back to continue soaking.

Allen has been practicing the same magic pattern for the past ten hours, and he is very familiar with it. He picked up the magic pattern pen and started wandering around the cards.

Ten minutes later, Allen drew the last step and the first card was successful. Allen showed a satisfied smile.

……

Seven days later, Mr. Borgin came in for inspection. Looking at the cards on the table that glowed green, he couldn't help but fall silent.

The newly completed deck will glow and then go silent for a few days without affecting functionality.

However, normal blood-stained playing cards emit gray light spots, which are negative energy in the blood.

Alan's finished blood-stained playing cards were green, which Mr. Borgin didn't quite understand.

"What is this playing card of yours?"

Allen grinned and said: "This is a healing card, which contains ten kinds of healing magic. For the convenience of use, I changed the passive to active. You can choose to use the healing magic by yourself."

"This is a healing card that I modified from the blood-stained card. As long as you have a stack of healing cards, most injuries can be treated."

Since the material is relatively low-grade, it can only be used once a day.

Mr. Borgin was silent for a while and then said, "I teach you black magic props, and you change them into white magic props. Don't you think there's a problem?"

Allen quickly shook his head: "In general, this healing card is still a blood-stained card, but I changed the magic."

"Not only that, the blood should also be changed. If it is evil blood, it is impossible for it to emit this kind of light."

Mr. Borkin glanced at Allen; "And it uses your blood. It seems that your body is different from ordinary people."

"Teacher, how did you figure it out?"

Mr. Borgin snorted: "Among the currently existing animals, only the blood of the phoenix and the unicorn is full of vitality."

"But the phoenix belongs to fire, so the light spots it emits should be mainly red, while the unicorn is mainly white."

"I really don't know which creature the blood you are using comes from, but the blood on the blood-stained cards must be fresh. The blood I gave you was obtained yesterday and added with a preservation agent."

"When you can't go out, you can only use your own blood, so I guess the blood used by the cards is your blood."

Allen applauded very appreciatively: "Sure enough, the teacher is really awesome, you can see it at a glance."

Although Mr. Bojin's face was still gloomy, the curve of the corners of his mouth showed that he was in a good mood.

"You will rest for a week and then take the third assessment." Mr. Bojin turned and left.

……

Allen slept in the alchemy room for a day, drank several bottles of nutritional potions, and his fatigue was gone.

Taking advantage of his free time, Allen went to Flourish and Blotts Bookstore to buy third-year textbooks. Yesterday, Owl sent a list of books. In addition to regular course textbooks, there are also elective course textbooks to buy.

There are five elective courses at Hogwarts: Ancient Runes, Divination, Arithmancy, Care of Magical Biology, and Muggle Studies.

Allen had already taken elective courses last semester, namely Ancient Runes and Conservation of Magical Biology.

Allen is not interested in divination. Divination relies purely on talent. Without talent, it is basically impossible to get started.Alan comes from a Muggle family and it is impossible for him to have the ability of divination and prophecy.

Not to mention Muggle Studies, which can be completely abandoned.

Since he had to choose at least two elective courses, Allen could only choose Ancient Runes and Conservation of Magical Biology.

Some top students take all electives for wizarding exams, such as Percy who received twelve certificates in his fifth year.

If you get the same twelve certificates in the Higher Wizarding Level Examination, you can find a good job in the Ministry of Magic. For example, Auror needs better results, especially in Potions, Defense Against the Dark Arts, Transfiguration, Herbalism and Magic. For these five curse courses, you must get an E (the highest score).

But with Allen's ability, he can go anywhere he wants, so he just needs to choose two elective courses.
