This thing is horrifyingly cool, although you have to pay 5 dollars or euros or whatever to have it. You tame it by killing one and taking the altar in its inventory, and it’s level varies from whatever level you kill. I recommend going near your base because when you place the altar it will ask for a random assortment of apex drops. Keep in mind It has to be night for it to work. If you don’t have what it’s asking for and it’s timer runs down, it will spawn the alpha creature that drops what it’s asking for. After you give it the apex drop it will spawn and you have to kill it within three minutes. If you don’t kill it then it will lose taming effectiveness. Do this a few times and you will have a dreadmare/stallion!(depending on if it is a male or female)
