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!
