The Thief's Downfall Mission

Your search for Horcruxes and your desire to destroy them will led you to the dungeon of Gringott's Bank. To get on the right path you have to shoot five red signs (then they will turn green).

You will get to a square guarded by a dragon. Approach the cart and flip it over. Under it you will find some bricks - use them to build a pink platform.

Switch to Hermione and use her magical bag. Remove the mechanical bull from the bag. However, you have to activate its mechanics (rotate it a few times).

To get the key, required to activate the bull, you have to approach the dragon. Next to the post there is a hammer. Pick it up and hit the sphere hanging on the post. The desired key will fall out.

Go back to the bull, activate it and direct it towards the dragon. This way you can reach the treasure repositories located at the end on the right.

As soon as you get inside Bellatrix treasure chamber you have to grab a goblet located in the middle.

Then approach the two swords hanging on the right, remove them from the wall.

Head to the fire on the left and destroy it. Use AR spell to extinguish small flames left after the campfire. Climb on the pink platform and use Hermione's bag. Take out a bird from the bag which will left a feather. Use the latter to giggle the head of the serpent.

This will allow you to obtain bricks - use them to assemble a mechanism which can open the chest. A new cabinet will appear - use Harry to solve a puzzle.

You have to build another mechanism from more bricks. Switch to the Goblin and use his key to move the lamp with the light down.

Use Ron's Deluminator to collect lamp and transfer it to similar lamp on the right side of the room.

You will get rid of devil snares (vines) and then you can rotate the crank. This will lift the glowing lamp and destroy another vines.

Select Hermione and climb up - there you will find a pink platform. Use it.

Return to the hall with a dragon. You main objective is to set the dragon free.

Approach the first chain, extinguish the flames and find a pink platform. Hermione will take out a pickaxe from her bag - destroy two rocks that block your way to the bolts.

After getting rid of the stones, remove the bolts by using the WL spell. Destroy pink securities to get rid of another chain.

Switch to the Goblin and approach the mechanism on the right. Move the lamp down and collect the light by using the Deluminator.

Once again, with the help of a Goblin, you have to approach a similar mechanism on the left. Move the lamp down and transfer some light to it by using the Deluminator.

Devil snares (vines) are no longer a problem. Take out the bolts. After you jump on the dragon, you have to shoot (5 times) a goblin who has stolen a sword that destroys Horcruxes. Switch to Hermione and target the goblin that appears on subsequent balconies. When you can't track him, switch to Harry and move the dragon to another spot.
