About halfway through Poppy Sweetings’ questline, her focus changes from the dragon egg to the Snidget, a rare creature that is thought to be extinct. From here on out, you and Poppy start to look for how to gain access to these creatures with the help of the centaurs. The Centaur and The Stone is the second dungeon you will enter in for Poppy’s sidequests, and it can be a bit confusing to get through. The guide below goes over how to complete The Centaur and The Stone and grab the moonstone.

How to Start The Centaur and The Stone in Hogwarts Legacy¶

Meet Poppy outside of Irondale, and speak with her. Afterward, head into the Moonstone Garden. You must have also completed the story quest, In The Shadow of The Mountain.

How to Complete The Centaur and The Stone in Hogwarts Legacy¶

The first room you will encounter is sealed with two moth spinners on each side of the door. Use Revelio to locate the four Accio levers in the room. The moths are hidden behind the walls underneath these levers, and the walls show the symbols you need to line up with the levers in order to open them up.

Hit the levers with Accio on the left side of the room. This will open the first door, and use Lumos to carry the moth to one of the spinners.

The answer to the first moth puzzle.

You will now want to use Accio on the lower right handle and the left handle with the circle below it. This will expose the second moth, use Lumos to bring it to the second pedestal, and then hit them both Depulso until they stop spinning to hit the door. Before proceeding inside, use Lumos again to regain the two moths and head into the next room. Here you will find another two moth spinners on each side of the room, deposit your moths here and once again hit them with Depulso until they stop spinning.

A bridge will come up from the water, and a third moth will appear in the water below the bridge. Use Lumos to collect the two moths from the spinners and grab the new one. You will now take them to the door to open it. You will encounter some Great Spined Dugbogs, defeat them, and then proceed into the water. It’s here that you will dive into a whirlpool.

Once you emerge from the whirlpool, you will be in a room with a giant tree. Get out of the water and follow the path forward. There are some vines that will be in your way. Use Confringo or Incendio to remove them and follow the path up to the tree. It’s here that you will find the Moonstone. Once you get back outside, it will be placed in a stone, and a group of Mooncalfs will perform their dance. Wait until the next day to get another owl mail from Poppy so that you can start It’s in The Stars.
