Snape asked Harry Potter three questions and their answers:

1. "If I add narcissus root powder to wormwood extract, what will I get?"

Narcissus root powder and wormwood can be made into powerful sleeping pills, which is a dose of water for life and death.

2. "If I asked you to find me a piece of bezoar, where would you look?"

In the stomach of a cow.

3. "What's the difference between aconite and wolfsbane?"

It makes no difference. It's all aconite.

Snitch: Snape needs to constantly adjust the position of himself and his doppelganger, and the steps brought by Snitch are indispensable.

1, the starting situation, playing Bella province, afraid that the other party will directly accept 10, a set of creatures+twins will suffer too much, and the rest of the time can be started;

2. Give priority to the snitch after the defense earns money;

3. Unless the attack gap can be crushed to death, the Snitch will snowball.

Flashback: advance can be offensive and defensive, flexible and easy to use.

1, flash back to the doppelganger and snowball. When you can't make a doppelganger on the opposite side, flash back to the doppelganger, and the two doppelgangers in the triangle station should not be too close;

2. Flashback to flying sand to solve the problem. When I hit Bella, I faced three books+partners+dead disciples, and two flying sands solved the problem rhythmically. When playing the game, fly in+double flying sand to solve the partner or double flying sand to disrupt the formation and fly again;

3. When the flashback is strong, the acceleration stage consumes a lot, so you can go to double god Front, which can break the field and cause great damage.
