How to unlock the Diffindo spell in Hogwarts Legacy - Ultimate Guide

In order to unlock the Diffindo spell, you must first obtain two special potions: the Invisibility Potion and the Thunderbrew Potion. Fortunately, these potions can be easily acquired by visiting the wizard Mr. Pippin in Hogsmeade. He will be able to provide you with either the potions or the recipes for both of them at a price of over 1,000 Galleons. To brew either potion, you will need to gather the specific ingredients and a potions station. 

For the Invisibility Potion, you will need one Leaping Toadstool Cap, one Knotgrass Sprig, and one Troll Bogey. For the Thunderbrew Potion, you will need one Purple Bitterroot, one Kneazle Claws, and one Bicorn Horn. 

Once you have acquired the potions and the ingredients, you can begin brewing the potions. The Invisibility Potion will be used to unlock the first part of the spell, while the Thunderbrew Potion will be used to unlock the second part. 

The Invisibility Potion requires a few steps. First, you must gather the ingredients, then add them to the cauldron. After that, you must light a fire and stir the ingredients until the potion is ready. Once you have done that, the potion will turn a silvery color and you will be able to drink it. 

The Thunderbrew Potion also requires a few steps. First, you must gather the ingredients, then add them to the cauldron. After that, you must light a fire and stir the ingredients until the potion is ready. Once you have done that, the potion will turn a golden color and you will be able to drink it.
