LEGO: Harry Potter Years 1-4 Guide

Unofficial LEGO: Harry Potter Years 1-4 Guide by Vhayste for


This walkthrough is meant to assist players maximize their initial run. You can replay previously played chapters so don't fret about missing anything in your first playthrough. You will encounter locked paths, chests and objects but don't worry; the spells and characters you need can only be acquired late in the game so don't feel bad about missing them initially. This walkthrough will list the stuff you can backtrack as soon as you have the means to access them.

The same goes with crests; previously acquired crests do count so it means you just need to gather the other pieces again per story chapter. The walkthrough will discuss how to get the crests that you can access without the need of special magic or character. You need two vital things to unlock most of the stuff: the spell Reducto (RE) that can unlock silver locks, chests and gates and the dark version of  Wingardium Leviosa called Crucio (CR) exclusive only to dark arts characters. Reducto is automatically learned after complete chapter 2 of Year 4 while the earliest dark character (Tom Riddle) you'll find is in Year 2, chapter 6. (Free play)

Another thing to note is that this game has some really annoying glitches that may prevent you from getting 100%. To be safe, I suggest keep a backup of your save game using a USB storage device of your choice. Its better to redo a few chapters than to do restart the whole game, if you're after getting all unlockables.

Finally, I am not a Harry Potter fan so excuse me if I don't know the common names of most of the characters nor the fancy terms used to call various stuff. So don't go emailing me correcting my spelling of their spells or telling me to change the names/ terms used in this guide.

How do you get past the Boulder and into the girls' bathroom?

Get up on the shelf with the knight next to the water and send a spell his way, he'll drop some pieces that you build and give to the mermaid statue. After they hit the boulder away you need to build and give the wizard in the picture a light. Aim at him and send a spell his way, he'll turn you into a girl for a brief period of time so go straight to the door and wave at the picture.

Levitate the knight and build it. Don't forget to place the spear! It will release the student.

I have the night and the spear in place but it says will not release the student. Am I missing something? I can't get out of the room and the student is still hanging in there even though the night is fixed and the spirit is it his hand.

One of the branches of the whomping willow has a circular space you can jump into. Wait for this branch to hit the ground, then press "U" to jump in. When the branch picks you up, cast at one of the willows in the centre. There are three. Each time you hit one, the tree loses some stamina and places you back down. So you must repeat the process until you have hit all three willows.
