Exploring the halls of Hogwarts in Hogwarts Legacy reveals numerous secrets, including mysterious doors decorated with animal symbols and numbers. These Arithmancy doors can seem puzzling at first, but they follow a clear mathematical logic once you understand how the creature icons correspond to specific numerical values. Mastering these doorways allows players to access hidden rooms packed with gear, gold, and collectibles throughout the castle.
Understanding the Animal Symbol Values
The key to unlocking Arithmancy doors lies in recognizing that each magical creature represents a number from zero to nine. Surrounding the archway, the animal symbols are arranged in sequential order from the bottom-left to the bottom-right. The Demiguise stands for zero, the Unicorn represents one, and the sequence continues up to the nine-headed Hydra for nine.
Remembering that the sequence starts at zero rather than one is the most common hurdle players encounter. Once you keep this numerical sequence in mind, reading the door frames becomes a straightforward process.
Solving the Arithmancy Math Equations
Interacting with a puzzle door reveals two triangle diagrams containing numbers and creature icons. The large number in the center of each triangle is the target sum you must reach using the three surrounding points. Your goal is to determine the missing value represented by the question marks and select the corresponding animal symbol on the wall rollers.
To solve the top equation with a single question mark, add the two known values together and subtract the total from the center number. Repeat the same calculation for the bottom equation to solve for the double question mark.
Locating the Rollers and Claiming Rewards
Near every door, you will find two interactive wall dials marked with a single question mark and a double question mark. Roll each dial until it displays the creature symbol that matches your mathematical solution. In some instances, a roller might be hidden on an adjacent wall or a different floor level nearby, requiring a quick scan using your Revelio spell.
Once both rollers are aligned correctly, interact with the door again to watch it swing open. Inside, players are typically rewarded with gear chests, gold, and unique decorative items for the Room of Requirement.
