Hogwarts Legacy – All Vivarium Biomes And Upgrades Guide

Hogwarts Legacy allows you to capture and tame dozens of magical creatures. However, you’ll soon find out that the space in your Vivarium, a sanctuary for animals in the Room of Requirement, is quite limited. Thankfully, there’s a way to remedy the issue somewhat, though it’s going to take quite a bit of progression. Here’s our Hogwarts Legacy guide to help you unlock all Vivarium biomes. These are, technically, the only way to upgrade the game’s Vivarium mechanic.

Unlocking Vivarium biomes in the campaign

Just a quick recap: The default Vivarium in Hogwarts Legacy has space for 12 animals, but you’re only allowed a maximum of 4 different species. As such, if a biome already has a Unicorn, Hippogriff, Thestral, and Puffskein, you won’t be able to add something else, like a Giant Toad.

That means the only method to acquire a Vivarium upgrade is to unlock an entirely different biome altogether. This is done by completing Deek’s sidequest arc.

Coastal biome

The second Vivarium biome that becomes available to you is the Coastal biome. The requires the completion of The High Keep, where you’ll also earn your flying mount. You’ll then receive a quest called Plight of the House Elf. The moment you start this quest, a cutscene will play, showing you the new beach location.

As for the Plight of the House Elf objectives, it involves entering a cave and battling a lot of spiders, including an Acromantula.

Swamp biome

After completing the Plight of the House Elf, as well as a main quest called Charles Rookwood’s Trial, Deek will have another task for you. The quest, Foal of the Dead, unlocks the game’s Beast breeding mechanic.

Mountain biome

The fourth and last Hogwarts Legacy Vivarium biome that you can unlock takes you to a quaint area nestled on a mountain. To get it, finish the Niamh Fitzgerald’s Trial quest, which gives you access to the Phoenix Rising sidequest. Upon completion, you’ll be able to enter the biome, and you’ll even have a very unique pet.

At the end of this entire endeavor, you’ll have four Vivarium biomes, which means you can have numerous animals in each in spite of the species limit per location.
