1. Locate demon horsy on The Center or Scorched Earth (ONLY SPAWNS AT NIGHT)

2. Kill it

3. Collect alter from lifeless corpse

4. DO NOT PLACE ALTER IN BASE! (explanation #13)

5. Place alter somewhere open

6. Summoning can ONLY TAKE PLACE AT NIGHT

7. The alter will ask for boss tributes (any alpha trophy from the current map + its RANDOM)

8. 5 minute timer to place in the required tribute

9. After each tribute is placed, the Dreadmare will be summoned and you have 3 minutes to kill it to progress taming.

10. Flys very fast in a circle and keeps its distance.

11. Best to use medium to long range weapons such as rifles and bring a Wyvern, Giga, Carch or Rex to help with fight.

12. However...if you don't feel like chasing Evil Pegasus around, you can build a trap around the alter ;) Suggest 3x3 floors around the alter and above, and 24 doorways at 2 height. Make sure there is an opening on the ceiling above alter to match the floor

13. If you do not place the required tribute within the given time, a high level dino of the given tribute will spawn. (Ex. Alter calls for Alpha Rex tooth, if the tooth isn't placed inside before time runs out an actual Alpha Rex will spawn!) keep that in mind if it ever calls for a giga heart ;)

14. Each time you miss a tribute, the alter loses health. You can miss a total of 3 tributes before the alter is destroyed and buh bye tame :(

15. Once the taming bar is at 100%, it will give you an option to tame and TADAAA! You have yourself a Horse from hell!

They demand amonite bile on Astraeos, pls add this to the list!!

All tributes on the map can be asked for. Asked for sauropod vertebra on SE: summoned the titanosaur. Somehow I lived. Successfully tamed a lvl 15 😐

DO NOT knock it out. Glitches the dreadmare and makes it so it doesnt eat and you cant go in its inventory when tamed.

I recommend having five of each type of apex drop and trophy before you try and tame one. However you don’t need any aquatic apex drops, meaning that megalodon fins, megalodon teeth, basillo blubber, alpha leedsicthys blubber, alpha mosa teeth, tuso tentacles, and alpha tuso eyes are not needed. However in the list of things that are required are the alpha apex drops (alpha raptor claws, alpha carno arms, alpha Rex teeth) plus giga hearts. The easiest way to acquire the heart would be to lure a giga or carchar into lava on the island and center. Also just to clear up something, rhino horns are not apex drops and are not necessary. They can also request trophies, so the alpha Rex skull trophy, alpha wyvern trophy, and alpha death worm trophy. The apex drops it wants will always be available on the map you’re trying to tame it on, so you don’t need to worry about collecting wyvern talons on the island or the center. On Scorched it is harder as most of the requests are one of the three wyvern talons, plus a lot of alpha death worm trophies and alpha wyvern trophies, which are pretty hard to get, so I’d tame on the island or center.

It’s about 6 hours on 2x to get to juvenile. They eat spoiled meat.

Taming a 150 on x2 official center.

Genuinly asked for 6/21 megalania venom. It can and will ask for the same thing over and over again so beware. And ark always knows which thing you are low on or missing!

While taming 145 the alter asked for a cera venom spine twice

Ceratospine is also 1 of the needed trophys. Please add
