Bow to Your Masters

Horde only achievement.
You need to find and /bow to 9 NPC on Zandalar island.

The only problem is that some of them could be gated by quests.
If you got Secrets in the Sands and The Dark Heart of Nazmir and The Throne of Zuldazar you probably just need to complete Kimbul and Jani

TomTom is kinda buggy right now espesially in zuldazar
Zuldazar:Zandalar but don't use it in Dazar'alor

Update Rezan was fixed on live.

I have updated the Waypoints with zoneID's so you can macro them regardless of where you currently are. This will be helpful for the Micro Meta Achievement [achievement=41202] which is part of the new BFA Meta Achivement introduced in 11.0.7 A Farewell to Arms.

/way #864 27.04 52.58 Sethraliss
/way #864 57.00 10.88 Kimbul

Note: If you are unable to pass through the wall to see Kimbul, you'll have to complete the short Kimbul quest chain that was outlined perfectly from this comment.

If you forgot to /bow Rezan during the whole storyline in Zuldazar (like I did), just enter the Atal'Dazar dungeon on any difficulty, run down to Rezan (you don't need to aggro him) and /bow him.

If you have the setting to show who your target is targetting, after you /bow you may see him target you for a split second. Don't worry.

Worked for me as of patch 8.3.7. Don't think this functionality will be removed.
