Fluxweed is an ingredient used in potion making.
Fluxweed is used to brew the following potion:
- Behind the willow root in Book 2, Chapter 5, Moment 2 .
- It is collectible after the car has backed up from the willow. Some people appear to have trouble collecting it; this is most likely due to the size of their browser/screen. Making the browser full-screen and/or changing the screen resolution should solve this problem. Size 1280x800 works. Double click until the car backs up and you can collect the fluxweed.
- Also, you can't pick up the fluxweed untill the Whomping Willow is done beating up your car. After the rear-view mirror falls off and after the screen zooms out, you should be able to pick it up.
- If you cannot move the car, look at the far end of the screen, on the right of the steering. You should see a faint outline of a weed which you can click on to collect it.
- In front of a wooden crate in the third layer in Book 3, Chapter 16, Moment 1.
- On the left side of the Whomping Willow in Book 3, Chapter 17, Moment 1. (You have to zoom in first)
- Book 7, Chapter 4, Moment 1: "The Decoy Harrys". Once you zoom in, it is near the back building.
