Hogwarts Legacy: Vivarium Upgrades [All Biomes]

It's time to create your own army of Thestrals in Hogwarts Legacy!

Among all the features and things to do around Hogwarts, the Vivarium has to be one of the safest places where you and your creatures can chill at. Here you’ll get to keep your creatures and look after them in Hogwarts Legacy.

Vivariums are placed inside the Room of Requirement, however, the Vivarium Biome you get at first will have a limited capacity which will eventually call for an upgrade. Hence, it’s essential to know how to Upgrade your Vivarium in Hogwarts Legacy if you’re planning to house more creatures.

Key Takeaways

    • Grassland Vivarium: Unlocked after completing the “Phoenix Rising” side quest.

Here are all the Vivariums you can unlock and use in Hogwarts Legacy:

In the Vivarium biome initially unlocked, you can only house 12 Creatures from 4 Species. Adding a fifth species to the Vivarium with 4 different ones is not possible, and the maximum number of Creatures in a single Vivarium is 12.

Forest Vivarium

The first biome you unlock for your creatures, after completing “The Elf, the Nab-Sack, and the Loom” quest, is the Forest Vivarium. In the quest, Deek will teach the player about the Nab-Sack along with its uses.

The house-elf will take the player to the outskirts of Hogwarts and teach them to catch different Creatures. After successfully capturing a Puffskein, Jobberknoll, and a Mooncalf you’ll be tasked to head back to the Room of Requirement.

  • Upon reaching the secret room, a new cutscene begins, featuring the character summoning a Vivarium in the Room of Requirement.
  • The first Vivarium obtained provides a Forest Biome, allowing the player to deploy 4 Species and a total of 12 Creatures.
  • After releasing initial creatures, Deek assigns a task to feed and brush them, rewarding the player with valuable resources.
  • Before the quest concludes, Deek acquaints the player with the Loom and demonstrates how to use creature resources on it.
  • Unlocking the first Vivarium is straightforward by following the steps outlined in “The Elf, the Nab-Sack, and the Loom” quest.
  • However, as more creatures are collected, the need for additional Vivarium space becomes evident

Swamp Vivarium

After you play through the main storyline and side quests for a while, you will run into a quest called “Foal of the Dead.” This quest will yet again be related to Deek, who can be found in Room of Requirement. By completing the quest players will unlock a whole new Swamp biome Vivarium and not only that but also the ability to Breed creatures inside the Vivarium using a breeding pen. 

So in conclusion, you won’t just be getting a new space for your Creatures but also the feature to let them breed and create offspring. Like the first Vivarium, the Swamp biome Vivarium in Hogwarts Legacy will also have a limit of 4 Species and 12 Creatures.

  • In the “Foal of the Dead” quest, purchase the Breeding Pen Spellcraft from Tomes and Scrolls for 1,000 coins.
  • Obtain a male and a female Thestral to use in the new Vivarium.
  • Upon returning to Deek, a new Vivarium manifests in the Room of Requirement, expanding overall creature capacity.
  • Inside the Swamp Vivarium, use the Conjuration spell to build a Breeding Pen using 15 Moonstones.
  • Release the captured Thestrals from your Nab-sack into the pen and initiate a 30-minute breeding process.
  • Complete the quest by talking to Deek.
  • Unlock the second Vivarium, increasing capacity and enabling the creation of Breeding Pens

Coastal Vivarium

The next Vivarium comes during another one of Deek’s side quests. However, the quest is totally unrelated to Vivariums and rescuing creatures themselves. Nevertheless, after you have played through “The High Keep” main quest, a new side quest will unlock titled “Plight of the House Elf”. During the quest, Deek will request you to visit the caves to check on his friend, another house-elf, called Tobbs.

Although, when you initiate the quest, the new Vivarium will get conjured up right away. Hence, there isn’t really anything else you need to do in order to unlock it. Just starting the side quest will be enough to have the new Coastal biome Vivarium upgrade unlocked in Hogwarts Legacy. Like every other Vivarium, the coastal biome will also be able to hold up to 4 different species and 12 creatures in total.

Other than that, you can conjure up the same items as the other two Vivariums. You can even place a Breeding Pen if you want!

Grassland Vivarium

Believe it or not, but after a while, even 3 Vivariums won’t feel enough. Hence, you will undoubtedly wish for yet another Vivarium Upgrade. Fortunately, there is one more Deek’s side quest that players can take part in to unlock the final Vivarium Biome in Hogwarts Legacy. So to unlock the final Vivarium you will need to complete the “Phoenix Rising” side quest given to you by Deek.

Although, it is worth mentioning that this quest will appear in the later stages of the game. Hence, get ready to put in some additional hours before you get the Grassland Biome Vivarium in Hogwarts Legacy.

  • In the Phoenix Rising quest, Deek tasks you with rescuing a Phoenix from the nearby mountains.
  • Venture into the mountain caves to locate and capture the Phoenix in your Nab-Sack, facing Poachers and Scurriours along the way.
  • Upon reaching the mountain’s summit, approach the Phoenix, use your Nab-Sack to rescue it, and return to the Room of Requirement.
  • In a cutscene, release the Phoenix in front of Deek, triggering the conjuring of a new Vivarium.
  • Enter the Grassland Biome Vivarium, the final upgrade capable of hosting 4 Species and 12 Creatures, similar to the others.
  • Completing the “Phoenix Rising” side quest unlocks all Vivariums in the Room of Requirement

How To Capture Beasts For Your Vivarium?

As we mentioned earlier, you can rescue all kinds of creatures using the Nab-Sack that Deek gives you during the “The Elf, the Nab-Sack, and the Loom” side quest. Although rescuing beasts can be a little tricky, you will need to devise a specific strategy to get them. Players can use the Disillusionment ability to sneak up on the creatures so that they do not startle them while capturing them.

Other than that, you can also use Spells like Leviosa (to make the target levitate), Glacius (to freeze and immobilize the creature), or Arresto Momentum (to slow down the creature). After using these spells you can try using the Nab-Sack on some of the creatures. All in all, rescuing the creatures in the sack can be a bit tricky and requires patience. Especially for creatures like Unicorns, Thestrals, and Hippogriffs.

After rescuing creatures, return to the Vivarium in the Room of Requirement to release them from your Nab-Sack. You can then interact with these creatures by feeding, petting, and grooming them. Additionally, once you’ve completed the “Foal of the Dead” quest, you’ll gain the ability to breed these creatures.

Here are some other important details to keep in mind about the Vivarium and creatures in Hogwarts Legacy:

  1. If your Nab-Sack is full and you don’t plan to deploy some of the creatures in the Vivarium, you can give them to Madam Peck at the ‘Brood and Peck’ shop in Hogsmeade.
  2. She will pay you for the creatures you bring to her shop.
  3. Creatures, when properly cared for through grooming and feeding, may occasionally provide you with valuable magical materials.
  4. These creature materials can be used to upgrade your clothing and gear in Hogwarts Legacy.
  5. You can perform these upgrades using the Enchanted Loom, which can be summoned within the Room of Requirement.
