The Flaw in the Plan

The day has come, and the struggle between good and evil continues. Destroy the stones blocking the way to Harry. To do this, put 3 ingredients into the cauldron.

First, you have to go to the fallen stones and pull the cauldron out of the wreckage. Use WL spell to do this.

The first ingredient is under the red box. Destroy it and then throw the ingredient into the cauldron.

The next one is held by a giant - don't worry, he won't wake up. Take the ice out of his hands and add it to the broth.

Go to the greenhouse on the left side of the square - you will find bricks scattered around. Use them to build a pot and then water it with AG spell. Soon, the last ingredient will appear.

Choose Molly and use the orange box - set off the fireworks. This opens the passageway.

Use the bricks to build a footbridge and cross it.

Use the AG spell to extinguish the flame. Use the burned bricks to make a counterweight and hang it under the ceiling. Another part of the footbridge will raise.

When we get to the next chasm, we jump down and build a ramp - use it to reach the other side.

We fill in the last gap by lifting the footbridge with WL spell and putting it in place.

Time for a fight - after each wave of Death Eaters, we will face Bellatrix. Each subsequent wave will consist of more opponents. The best tactic to avoid getting hit is to be on the move and keep using the WL spell - it is the fastest, which makes it the most effective against more opponents.

When we defeat her, she will disappear once and for all.

We go back to the fight in front of the castle. Our task is to defeat the snake, which is also the last Horcrux.

Time to fight more waves of opponents - each consecutive wave is bigger and more diverse. Due to the presence of Dementors, the most effective spell is EP. When a spider with a pink element appears, we attack it. The enemy will land upside down.

Raise the spider with the WL spell and throw it into the snake's mouth. We switch to Nevil and attack the snake with the sword.

Time for the last fight between Voldemort and Harry. Defeat the evil once and for all.
