Professor Sharp’s Assignment 2 – Hogwarts Legacy Quest


Once again, Professor Sharp is encouraging you to use substances to increase your performance. This time he will teach you the Diffindo spell if you can find and use two different potions.


Acquire and Use an Invisibility Potion

This is relatively straight forward and easy. If you haven’t done the quest A Demanding Delivery yet, this is the time because during the short quest you will use an invisibility potion, hitting two owls with one curse (is that the saying?). However, if you prefer a faster route, you can simply hop over to J. Pippin’s Potions and buy the potion for 500 galleons.

Yet, there is a bit of a trade-off with buying the potion. If you have the money, you might consider investing in the recipe for the potion instead. It is only 300 galleons more (800 total) and you will be able to make the potions at your discretion in the future. It will still be even more expensive though if you don’t have the ingredients, which you’ll have to buy.

If you choose the more expensive option and buy the recipe, you will need these ingredients to make the potion (note that you can buy them as well in Hogsmeade):

  • Leaping Toadstool Cap (1) – 150 galleons (Pippin’s)
  • Knot Grass Sprig (1) – 150 galleons (The Magic Neep)
  • Troll Bogeys (1) – 100 galleons (Pippin’s)

Acquire and Use a Thunderbrew Potion against Enemies

Just like with the invisibility potion, you can buy this potion at J. Pippin’s Potions, except this potion is much more expensive at 1000 galleons. Again, if you’re rolling in the galleons, then maybe buy the recipe instead for 1200 galleons.

Here are the ingredients you will need for the recipe:

  • Leech Juice (1) – 150 galleons (Pippin’s)
  • Shrivelfig Fruit (1) – 150 galleons (Magic Neep)
  • Stench of the Dead (1) – 100 galleons (Pippin’s)

It is important to remember that you will need to use the Thunderbrew potion against enemies. This can be done expeditiously by fast traveling to the Forbidden Forest Floo Flame and strolling underneath the perilous canopy; there are plenty of enemies around there.

Return to Professor Sharp

After using the two potions, you can return to Professor Sharp. The closest Floo Flame is aptly the Potions Classroom. Once there, speak with the professor and do the mini-game to learn the spell Diffindo, then the quest is complete.
