Have you ever wanted a powerful pet aether dragon? If you do, then consider yourself lucky. I made it in Minecraft. This addon adds an Aether Dragon, one hostile, and one tamable. Be prepared though, it will be challenging to get a pet Aether Dragon.
This addon provides an superb creature referred to as the Aether Dragon. This creature is a powerful one. Blasting powerful balls of ice at you, defeating this beast is quite the challenge. BUT, after destroying the beast, you receive a pet Aether Dragon. Make certain to bring a few golden apples to tame the Aether Dragon. When tamed, you can equip it with a saddle and a chest. The dragon will defend you with its life. The Aether Dragon will also drop Aether scales
