Expelliamus Challenge- On all of the spiked balls, use the spell that cuts ropes, tapestries, ect. and cut the ropes on the balls. once you do that, you will be able to go but, there will be a little creature waiting for you in the block that was in the way. They are easy, just use flipendo on them to knock them out. Next, you will go through a door. inside will be blades spinning  across a narrow way to get to the door. To do this, you must turn around and look up. You will find two ropes hanging near the doorway. Cut them with expelliamus and creatures will cow at you. You will have to cast expellamus at them, then pick them up and through them off the edge. as you are doing this, you will notice that the blades are slowing. When all the creatures are off the edge, you will notice that the blades almost stopped. Run across the narrow walk way and enter through the door. You will enter a room that has stone objects that spit fire. When they stop spitting fire, cast flipendo at them and run past them. Do this until the end.

Incedio Challenge- Basically after you return to the main room, all you need to do is to get the fires out. You can do this by casting flipendo at the pigs. You will notice that two platforms lift up. Quickly run up the stairs, and climb on the platforms and jump across to one side than the other side. ( You will probably need to cast Flipendo at the pigs a lot because the platforms don't stay up for very long.) Now put the fires out.

Beating the giant spider- First, you will need to get to the big spider, you can do that by following the other tiny spiders. ( They will try to kill you.) Use Incendio on all of the spiders that you see that will kill them. When you are fighting the huge spider, aim for the web and that will knock it down into a large pit. Then you will slip in after it. This is the easy part, all you have to do is move out of the way so that the spider rams itself into the wall enough times that it cracks it's shell and its under-belly shows. then use Incedio and cast it at its belly. Once you have done that enough times it will then die.

The Whomping Willow challenge- When you first enter the Whomping Willow's area, it will start pounding down its branches at you. Run to where you first came in and stay there until you see a small ball of light in the whomping willow's hand. Cast flipendo at that ball of light and the tree will slowly die. After you get caught by Snape, you will follow Ron back to the common room.
