Lesson 4 - Aguamenti mission

First, fill the tank held by the statue on the right. After filling the tank, transfer it by using the WL spell over the large flames.

Switch to Hermione, extinguish the rest of the flames, move the bricks away, and go to the bookcase.

After solving the puzzle you will get a green oyster, which has to be taken to green container filled with bricks. Fill the container with water so that the bricks can be lifted and you will be able to go up.

Fill the water tanks and activate the pump. The wizard from the picture will put out the fire and throw you a chest with many bricks.

Build a watering can. Fill it with water and water a large plant. When it unfolds its leaves, a green key will fly out of it.

Use the key to open the chest in which the Professor is locked. You will learn the Aguamenti skill. Follow the Ghost and leave Hogwarts.
