In easy words, kill a Dreadmare, usually spawns around sunset/night. Get the altar from its inventory and place it. ONLY USABLE DURING THE NIGHT!! One the altar is placed, make sure that you have the five dollar fantastic animals pack for it. The altar will ask for any kind of item, including giga hearts, carno arms, Megalania toxin, and similar items to that. Once you give the item, it will spawn the dreadmare again. Kill it, and proceed to give it the next item and continue that process until it is fully tamed. There is a timer, however, and if you do not obtain the item within that time period, the animal that is requesting for along with the dreadmare, will spawn. For example, if it is asking for a giga heart, it will spawn a giga along with the dreadmare. Whatever level dreadmare you were attempting to get, is the level of animal that will spawn. For more information, you have to kill the dreadmare between three minutes after it spawns, and same goes with the animal if you do not get the item the altar is requesting. After you get it, there are multiple abilities in which you have along with gliding like a griffin, a black hole in which pretty much cryopods and animal and it’s inventory, and multiple long-distance attacks. It is an extremely good PVP animal and I would suggest it fully. For more tips, just ask.
