This potion is made by using the Bird + Giraffe Hoof in the cauldron. This potion doesn’t have any stackable effects.
Consuming this one will give you the ability to double-jump & go twice as high as you normally can without drinking the potion.
However it still doesn’t make you jump high enough to reach hidden ingredients or get to the top of the beancano. So it’s still a pretty useless potion for now.
It might be helpful to use when completing the giant key quest for the witch in the cave with the lava jumping obby.
This Potion is spell number #37 in the potions book.
