Burrow and Hogwarts Glitch
This code is very useful, but has bad side-effects. First, you must find Ginny so you can go to Diagon ALley. Then, go through the way you came in and enter again. At the loading screen, you'll see a picture of the Burrow. But, when you start playing again, you'll be standing in Gryffindor Common Room! The nasty side-effects happen after you help Ron with the slugs. When Harry, Hermione, and Ron are talking, they'll start having the conversation that is supposed to happen after you finish fighting the Whomping Willow!
Defeating the Giant Spider
To defeat the Giant Spider in the Dark Forest, circle around him and cast Rictosempra. He will not shoot any spider webs at you.
Personal Requests and Notice Board
The Notice Board in the Gryffondor common room usually gives a location, but higher up as you near completion they start to give vague clues, such as "Could be anywhere on grounds". With personal requests, they do not ever really give you a clue, except the first one. However, the items are near the area in about a two acre search range.
Finding Lost Items
When in doubt, check Hagrid's Hut. Many of the lost items end up there.
3 Roots Needed
Search the left side of Hagrid's Hut, by the Herbology Center. From there, they all scatter (much like Neville's china set) behind Hagrid's Hut towards the Forbidden Forest. The person that wants these will give you the key to the Confiscated Items Room (six more cards and a bag to hold 200 Bertie Bott's Every Flavored Beans).
Lost Badge
Found on the Broom Flying Field, towards Hagrid's Hut and the Whomping Willow (still inside the Flying Court).
Lost Newspaper Article
Search the left side of Hagrid's Hut. Note: "Left" being if you were looking from his front door towards the castle (the side next to the Herbology Center).
Lost Wizards Hat
Found in a small patch of trees towards the Quiddich Court.
Neville's Crockery
Can be found close to the Flying Court and Hagrid's Hut. Up on a roof will be a multitude of his china set. Go about a fifteen to twenty five second flying trip from Neville (heading back).
Secretive Dragon Scale Gloves
The elusive gloves are by the lake, but not on land. They can be found just outside the Broom Flying lessons field, on the lakeside. You will notice a long strip is down low. On the far end are five torches (light with Incendio to get a Wizards Card), and in the middle somewhere should be the gloves.
Defeating the Whomping Willow
When the Whomping Willow starts to pound into the ground, hide in the corner where you entered its lair. The shock wave cannot reach you in here, unless you stray too far from it. Should you get hit, you should have refilled your potion Vile before you entered. Also, Hedwig will drop Cauldron Cakes and Beans for your aid. Note: Rapid firing technique is recommended. Lock on to the limbs after they finish pounding and fire a quick shot, then wait to lock onto the Willow's Eye. Then, fire repeatedly until it stops hurting him before running back to your hiding hole.
Defeating the Giant Mother Spider 2
While fighting it, you may notice little sacks being dropped and suspended by webbing. Shoot them down with Flapendo and collect health and Bean power ups from Hedwig.
Defeating the Giant Mother Spider
To get to it, use your Lumos spell to light the floor and follow the trail of spiders. Unlike the book, the spiders that are not normal size will try to kill you. Attack them with Incendio. When fighting the Giant Mother Spider, do not try to hurt the spider itself. Instead, use your Incendio spell to burn the web it has attached to the various trees. When done, it will fall into the pit and you will slip in after it. In here, just run around until it rears its head and exposes its soft under-belly. It is the only part that is susceptible to second level magic. Note: It is best to not charge and use rapid firing to get a little extra damage.
Forbidden Forest spiders
The spiders in the forest act as follows:
Tiny Black: Show you the path
Big Green: Jumpers (jump, run away, and jump again)
Big Red: Flingers (they spit)
Big White: Flingers (spit paralyzing venom)
Big Multicolor: Possible Jumper/Flinger mix.
Transformation spell
After you acquire the spell and return to the main room, use it to get across the room on the other side of the gargoyle. You will need to use the hardly visible ledges to cross. Hang off the wall ledge to escape nearing ghosts, and push down the slabs to make a bridge. Once this is done, you will have to fight the gargoyle. It is recommended that you get on the right staircase, halfway up. Then, use the spell on the last stone and the door will open.
Fighting with Expelliarmus
When in one of the few battles with Hogwart's students (just the Slytherin Gang, all others leave you alone), let them make the first shot and bounce it back. Just as you do, use your Flapendo with a quarter to half second charge to knock them back, thus trapping them with two spells to knock back, which they can never manage. Note: Beware, just as you finish casting Flapendo (depending on distance), you will be forced to use your Expelliarmus almost instantly.
