- I used Server hop (and Cross realm assist) so I could switch quickly to realms with Starlight Roses nodes available.
- Tomtom to create and use others waypoints. I've added one in this post for the last part of the Rank 3 quest chain.
- Sky Golem was my mount of choice so I could herb while mounted. From what i've heard you can use the this too, but I don't have it.
- Stonehide Leather Barding so I wouldn't get dismounted when mobs hit on me.
- Leystone Hoofplates to run 20% faster on my mount.
- And various damage buffs, so that I could kill mobs faster when needed.
- If you have quested enough in Suramar to unlock them, grab all of the buffs from the 3 mana addicts found in Shal'aran.
- Fly to or run to Irongrove Retreat in Suramar.
- Head towards the western part of the white curve.
This short route has the highest amount of active nodes available and when combined with server hopping is the fastest way that i've found to farm Starlight non stop. Unless there's many other players farming there's nodes available every 15-60s. It's faster when empty, slower when crowded, but even when it's crowded it's still a solid route simply because it's so short and you can hop through a ton of realms and get to the nodes faster than the competition that use this entire route from wow-professions.
You can extend the route if you find that works better for you, but i'd follow the flow of the herbs rather than just following any set route like a mindless bot.
- Farm Starlight Roses for as many hours as you need. Make sure to keep 20 Starlight Rosedust! A node will eventually give you the quest Insane Ramblings. Hearth to Dalaran. Turn it in.
- Accept Tharillon's Fall. Fly to Azsuna and run to /way 56, 26 Tharillon's Fall. Now use the 20 Starlight Rosedusts to summon Tharillon. You should be able to solo him. If not find someone to help you.
That's it! Congratulations at finally ranking up. Starlight Rose is probably the single most anti climatic herb to level to rank 3, since the only thing it does is this, but now at least this specific rng grind is over for you.
Enjoy Legion! Avoid the time sinks!
