‘Dissending’ for Sweets is an optional quest in Hogwarts Legacy. Garreth Weasley has an idea to make a new beverage, but he is missing a cruicial ingrediant — dried Billywig stings to be exact. He heard that Honeydukes has a supply of them within the store, and knows of a secret passage to sneak in and obtain some. However, he is on close watch so is unable to go himself. That’s where you come in.
To start the quest ‘Dissending’ for Sweets, you will need to speak to Garreth Weasley. To reach him, use the Viaduct Courtyard Floo Flame, go up one flight of stairs, then go up the stairs to the left (1). Then go up the stairs to the right and go into the Entrance Hall (2). Once inside, go up either stairs, and he will be just ahead when you reach the second floor (3).
Talking to him (with /) will begin ‘Dissending’ for Sweets, and he will ask for your help — he wants you to grab dried Billywig stings for him, but you will first need to find the secret passage into the Honeydukes’ Cellar.
Finding the Secret Passage
To find the secret passage, you must first locate a One-Eyed Witch statue. In order to reach it simply use the Faculty Tower Floo Flame, turn around, and the statue will be immediately to your left. Walk up to the statue and interact with it, and you will be taken into the secret passage.
Navigating the Passage
The passage itself is straightforward, but you will need to use a few of your spells to take care of obstacles throughout. Go through the path until you reach a broken down lift, then cast Reparo on it in order to use it (1). Once you reach the top, continue forward until you reach a wall of web. Cast Incendio to take down the wall (2), then you will see a platform on the ground (3). Use Levioso on it to lift it up, then climb on it to reach the ledge in front of you.
Continue forward until you see a large gap — if you look down the gap, you will find another platform to cast Levioso on (1), allowing you to cross. You will quickly find another gap afterwards. This time, you must cast Reparo on the platform before you can cast Levioso on it (2). After crossing the gap, you will find another wall of web to cast Incendio on (3), then turn left to continue.
When you find the final gap, you will need 3 spells to make it across. First, cast Accio on the contraption on the other ledge. Then, cast Reparo and Levioso on the platform to be able to cross over. Continue forward until you find a large door. To open it, you will need to cast Incendio on the two torches next to the door to light them, then stand on the platform in front of the door to press it down. Once the door is open, you will finally reach the ladder to take you to Honeydukes.
Finding the Dried Billywig Stings
Once you’re inside, simply follow the path until you reach a flight of stairs, but don’t go up them. Instead, look to your right, and the dried Billywig stings will be on top of a table. Grab them, and you will be free to leave.
Talk to Garreth
Return to Garreth, who will be in the same spot as when you started the quest. Talk to him to give him the dried Billywig stings, though you will have the option to charge for the material.
After speaking with him, you will have completed ‘Dissending’ for Sweets, and have a new Conjuration for your Room of Requirement!
