Stag Party

Easy Achievement for Level 120 Battle for Azeroth and Beyond...

1. Mythic Difficulty.

2. Get to the Fields of the Eternal Hunt.

3. Clear the fields of beasts. Do not kill ANY Stags or the Storm Drake. Kill all the Bears and Oxen, don't even bother killing the Valarjar Falconers/Humanoids or Fenryr.

4. If you've killed a Stag, you need to zone out and do something else for 30+ minutes, and the trash will reset, unless you were foolish and killed Fenryr, then you have to come back next week.

5. Once the extra trash has been removed, find the 10 stags. I marked them so they were easier to find later. You can mark 8/10 of them with the standard WoW raid marking utility. Right click on their portrait and start from the top. Skull, Cross, Square, etc.

6. Once 8 are marked, you'll have to memorize where the other two stags are. There's a nice path to follow from Fields entrance, over the bridge, all the way down to the Stag that is hiding behind the tree at 24.7, 54.3

7. Don't even bother engaging or attacking Fenryr or the humanoids surrounding it.

8. Ok, show time. Mount up, and run into the Storm Drake that is waiting by the entrance. I was able to stay mounted the entire time, and sure is a lot faster than running around.

9. Lead the Storm Drake to each of the stags, one by one by one until it has 10 stacks.

10. Kill the Storm Drake, I was able to kill it while it maintained the 10th stack of 'Killing Blow' on it the entire time.

11. ?

12. Profit. Achievement Completed.

This was a pretty fun achievement to get.

First, make your way to the fenryr area to the right in Halls of Valor. Once there, make sure you do NOT pull the dragon. Leave him there. Go around killing all the hostile mobs making EXTRA SURE you do not pull any of the yellow neutral stags. If you pull a stag and it dies you must reset the instance. Once you have killed all the hostile mobs, take note of where each stag is. There are only 10 stags, so make sure you know where they all are. Once you have done that, pull the dragon and get him down to 30-40%. Once you have done that, start kiting him around to all 10 stags. Each stag he eats gives him a buff that increases his damage and health by 10% stacking that lasts 1 minute. Once you have all 10 stacks kill him. If at any time you wipe or he somehow loses his stacks you must reset as you will not be able to do it.

I made a map of where we found the stags once we cleared trash. Not sure if it remains the same for everyone, but this is how we had it: http://imgur.com/a/pXjbD
