In Hogwarts Legacy, there are 12 Arithmancy puzzle doors scattered around the Hogwarts School of Witchcraft and Wizardry, and behind each one you’ll find a Conjuration and some gear for your collection. The doors are all unlocked using the same mathematical code whereby the creature icons correspond to numbers, and the numbers on the points of the triangles must add up to the numbers in the middle of the triangles.
All Arithmancy puzzle door solutions and locations
You can find the Arithmancy cheat sheet in a chest outside the Arithmancy Classroom, but if you can count from 0 to 9 you don’t really need it, as the creature icons are displayed in the same order around every door.
