Hey, I'm about to do a run called "All collectables in Free Play 1-4"

Meaning you'll need a savegame with neither any hogwarts crests and character tokens collected nor a true wizard state reached and even no student in peril saved (except the one in 2x6 "The Basilisk" that you free in story mode) in every level.

I'm just creating this savefile for me, if you want to add this category, I'll put it into the resources (the one which is already there, unluckily collected ONE SINGLE character token in 3x3).

I was looking into a run like this too, but I was leaning towards just collecting Crests and Truewizard, because you need other characters to get all the Crests. And students in peril, you can't collect them all in levels anyways, and you get a purple stud if you have already saved them which can help get TW, which is really hard in certain levels.

If you have the story mode completed, you got the reducto-charm (which in real is reductio in books/movies/lhp5-7). With this you get ① griphook (key) in 1x1 ② Lucius Malfoy (dark wizard & Slytherin) in 2x5 ③ Hagrid (strong) in 1x5 and ④ The Grey Lady (Ravenclaw) in 3x3

I won't include this in the savefile, so this is the first thing to do. You get Gryffindor (Harry, Ron, Hermione) and Hufflepuff (Justin Finch-Fletchley in the Polyjuice Potion-Room) by completing the story, so this is not a thing of this category. Collecting anything inside of Hogwarts should be banned.

After that you can do every level for the "real" run, tho the time of course starts before.
