Leviathan is one of many bosses you can encounter in Rune Factory 5. It lives in the Meline Crystal Cavern: Depths and has a chance to drop many rare items, including Crystal Fragments. Taming it will not get it to produce the items you need, but you will get an amazing monster to aid you in your adventures. Plus, it just looks super cool!

Still, this begs the question: can you tame it? Sadly, the answer is no. Leviathan is too tall to fit in your barn. It’s also very aggressive.

Fortunately, Leviathan is only one of few bosses that can’t be coerced into a friendship. Fun-sized monsters like the Cerberus and Needle Beast can be tamed with the right items.

To tame a boss monster, brush it until the music note icon stops appearing above its head. Then, repeatedly offer it an item it likes until it comes with you. Make sure there’s an open space in one of your barns!
