This section of IGN's Hogwarts Legacy Wiki Guide details all of the items you can conjure for beasts in the vivariums within the Room of Requirement. These items require Moonstone to make and some require a trip to Tomes and Scrolls to purchase their Spellcraft (which is a one-time purchase to cover their base build), some can be given as rewards from certain quests, and most are found in Collection Chests around the map.
It's worth keeping in mind that the Collection Chests are all randomized, so make sure to visit our page to see where they're located. You can find a couple hidden away in the vivariums as well, and they usually have beast-related items in them.
Below, you can find a breakdown of what Beast Items, Outdoor Items, Building Pieces, and Ground Surfaces are available, along with how much they are and where to find them.
