How to solve the Arithmancy door puzzle in Hogwarts Legacy

Once you've been sorted into your house in Hogwarts Legacy and are free to roam around the campus, you might stumble upon some mysterious doors with various symbols surrounding it and strange numbers on the front. Naturally, you will be drawn to open it, only to find it locked. These aren't doors you can open with your normal lockpicking spells, no matter how high you level them up. Instead, you will need to use your wits to overcome this obstacle. That, or simply follow this guide to open the Arithmancy doors in Hogwarts Legacy.

How to open Arithmancy doors

Arithmancy doors are essentially math problems in disguise. You're supposed to determine which animal around the frame corresponds to what number and then determine what numbers fit in the ? spots on the two triangles on the door's face. Put simply, to solve these puzzles you need to make the sum of the values of the three numbers and animals around the triangle equal to the big number inside the triangle. If you aren't sure how to do that, or the value of the arithmancy door animals, follow these steps:

Step 1: Interact with the door to see the interior triangles.

Step 2: Add the two known numbers of each triangle together. If you see an animal and not a number, check this cipher to convert it into a number.

Step 3: Subtract the number inside the triangle from the sum you just got.

Step 4: Take those two new numbers and find which animal they correspond to.

Step 5: Locate the ? and ?? symbols on the walls nearby.

Step 6: Interact with each of them until they show the correct animal.

Step 7: Once both have the correct animal showing, the door will open and you can claim the loot inside.

How to increase maximum carry weight in Dragon’s Dogma 2
The Arisen next to a bug in Dragon's Dogma 2.

One lesson you will learn very quickly in Dragon's Dogma 2 is that your Arisen isn't built to carry as many materials as you want it to. On a single trek through the world, you will be snagging fruits, herbs, monster parts, ore, weapons, and more. All that weight adds up fast, and you only need to go over half your weight limit before seeing negative effects. Sure, your pawns can shoulder some of that burden, but even then, you will need to start leaving things behind. There are no backpacks or stats you can increase to increase your carrying capacity, but that doesn't mean it isn't possible. You just need to look in a different place.
How to increase your maximum weight

There are two ways to increase your weight limit in Dragon's Dogma 2, but only one of them is permanent. That is to find and use special Golden Trove Beatles hidden in the world. These are big, gold glowing beetle-looking critters, usually clinging to trees or walls that you can grab like anything else. Once you find one, open your inventory and use it to permanently increase your weight by .015kg. That's a rather small increment, but there are dozens, if not over a hundred, of these bugs to find.

How to turn on item auto-pickup in Rise of the Ronin
A ronin on a path in Rise of the Ronin.

Rise of the Ronin is structurally a very different game from Team Ninja's previous series, Nioh. This new game not only features a new story, but a full open world as opposed to smaller stages to navigate. The games do share two main components: challenging combat and tons and tons of loot. Between all the materials you can snag while roaming the countryside and drops from fallen enemies, you will be collecting hundreds of items every hour. While mission rewards are automatically added to your inventory by default, normal items are not and require a button press to collect. Luckily, you can enable an auto-pickup option despite the game never telling you about it.

How to revive the dead in Dragon’s Dogma 2

Death comes at you fast in Dragon's Dogma 2. While you have the luxury of being able to restart from your last save after death, and pawns can be revived or summoned again, if an NPC bites the dust, then you need to act fast if you want to bring them back. Just like fast travel, however, reviving the dead will cost you a rare and limited resource. This isn't an item you will happen across during normal travel or find on sale in a shop. If you lost an important ally and need to bring them back to life, we'll show you the way.
