Last update: 05 January 2023

Expecto Patronum Mission

After returning from the winter holidays, you will head to the practice room. Each member of the army must defeat a Dementor. The first one should be defeated with the Expecto Patronum spell.

Afterwards, approach the pipes and move the ball inside them to the first button - now you can get inside. Select a character that can summon an animal. Get inside and walk through the whole maze.

The green key will fall out. Use it to open the locked cabinet. Another Dementor will appear - use the EP spell to get rid of it.

Approach the vines and use LM spell to bend them off, then activate the chain mechanism. Another Dementor will appear. Defeat it like the previous ones.

Shoot at two shields in the corner of the room and in return you will get some bricks. Build a trunk. Another Dementor will jump out - destroy it by using the EP spell.

Switch to Hermione and approach the bookcase on the left. Solve the puzzle and obtain some bricks as a reward.

Build a tool for setting a fire, jump on it and pump the last Dementor. Defeat him by using the EP spell. After these events you will permanently unlock the EP spell.
