LEGO Harry Potter: Years 1-4 Cheats and Tips

It depends on what part of the level your on. If your in the beginning, to sneak by filch in the slitheren dormetory is you will see a brown object, and you will use the spell transfiguration on it to form it into a object that looks like a book shelf with two ladders on it. Then you push the book shelf out in front of filch and he will walk away without seeing you. If your in the other part, then you'll see a red dot on you map. You'll see a yellow triangle sticking out of the dot. That's Filch's vision. DO NOT GO IN OR NEAR THE TRIANGLE OR THE RED DOT!!!!!!!!!!! When Filch's vision goes to the right hand side, then rush over to the statue. Then, you PULL it where the blue path leads. The bloody baron will do the rest. Hope it helped! :-)

If you Reducto the only Prefect in the level, "The Quidditch Match" 4 times, he will break apart, and you won't have to worry about him spotting you after you do this.

Go to the first game, [The Sorcerer's stone] and to level 7. Malfoy has taken Nevil's membrall and you have to get him on your broom. When he flies arownd a tree,go the oppisite way and do this while sneeking up on him or you will see him also turn arownd and fly away from you. Hope this helps!

to get by filch in slytherin pull the statue towards you.
