One of the best parts of Hogwarts Legacy is when you unlock the Room of Requirements. Not only can you decorate this room and use it for crafting, but you will also get a Vivarium to keep fantastical beasts in. Once you are able to use the Nab-sack, you can go to the various beast dens around the map and start collecting these creatures. The guide below lists every Vivarium beast in Hogwarts Legacy and the information you need to catch and find them.
Every Beast You Can Place in Your Vivarium in Hogwarts Legacy
There are a total of ten beasts that you can catch or earn for your Vivarium. Some beasts, like the unicorn, are going to be harder to catch than others, while beasts like the Mooncalf only spawn at a certain time of day. The chart below gives you every beast in Hogwarts Legacy, when they spawn, where their den is located, and what items you can harvest from taking care of them.
