LEGO Harry Potter Years 1-4 character guide

With LEGO Harry Potter Years 5 – 7 having been released recently now is a great time to revisit the previous game in the series and finish up any missing achievements. Perhaps the most elusive one is to find all of the various hidden characters. While most of them can be gotten by just playing through the levels and interacting with everything in sight a few of them are a bit trickier or require solving puzzles to get to. And that’s where we aim to help!

This guide is broken up rather simply – it goes stage by stage and explains what you need to have to unlock the hidden character and where to find it. Generally speaking, some of them can be gotten while playing levels but it’s usually best to focus on simply completing the levels instead of searching them. In many cases you will have to revisit the level in Free Play to unlock a specific character or two so waiting until you meet all of the requirements before bothering to revisit will spare you replaying each level yet more times than necessary.

Upon starting up the game you will automatically obtain the trio of Harry Potter, Ron and Hermoine. However none of them have any special abilities that are helpful to begin with. As they learn abilities through the years at school more abilities will unlock on the characters so it’s going to be a bit before they’re as useful as they can be. By and large the most useful abilities to have are strength (Hagrid), Reducto (most wizards) and Dark Magic (any Death Eater). Ron / Hermoine’s respective pets will come in handy in a few situations as well and the short characters come up a few times but the above trio of abilities are ones you will want ASAP, so buy the first Dark Magic user you can.
