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-veiw 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.
