This guide will let you know how to find Rococo in Hogwarts Legacy.
You will first need to go to the following location on the map and then head down the stairs near the building. After that, enter the dungeon.
Light the brazers down there, then grab that cube and put it next to the other on the symbol on the floor. Use the matching symbol to reveal the door.
Go through the door and find statues next to the Griffin. You must light up the brazers, flip the statue back, and then hit the switch. Jump up on it to flip to the other side. There will be a cube; use your spell to drag it on the symbol.
Afterwards, head down the stairs, and you will find a cube. Pick it up, put it through the door and use the spell that matches. Then it would be best to do the same down the other hallway and light it up.
Use your value, and the floor will glow blue. Aim your wand at the floor in front of the wall that eats you, and use all your spells on one of them. Then you will be able to get through. Next, you need to head upstairs and pull the cube towards you.
Go down to the symbol and plug it in. After that, go through the brick door and grab the musical map.
Grab the cube, then head upstairs and plug the cube in. You cannot use the downstairs to exit.
Now in the next room, you will find Rococo, use the capture spell on them and then you can sell them for 500.
