This guide will list the places where I found the most [Volatile Air]. One thing I noticed while farming Volatiles Air is that sometimes you farm for 15 minutes and you don't get a single Volatile, this is just bad luck, don't get discouraged.
Vortex Pinnacle - Uldum
Vortex Pinnacle is the best place to farm Volatile Air, and you can easily solo this instance from level 100. You can find the entrance high in the air in the southeast part of the Uldum, over the ocean. Click here for the exact map location.
First, you have to set the instance difficulty to normal (right click your portrait). You can't farm in heroic mode because you can't reset the instance after you kill the first boss.
Kill everything until the second boss Altairus, then just simply jump down, you won't die, it will teleport you to the start of the instance. Go outside and reset the instance by right clicking over your own portrait then click the "Reset all instance" button. This restarts the whole instance and all mobs will be back. You can only do 10 instance runs in an hour, this means sometimes you might have to wait a bit.
Zul'Gurub - dungeon
Since patch 8.0.1, you can only get one [Hive Queen's Honeycomb] a day. Not sure yet if this is intended, or a bug. But you can keep killing Tor-Tun, he will drop Volatile Earth 10 times.
Zul'Gurub is a level 35 heroic dungeon, so you should be able to solo this instance at around level 40. Scroll down to the bottom of the page to find alternative farming methods if you don't have a high level character.
The entrance to this dungeon can be found in Northern Stranglethorn at the coordinates 72 33. (picture of the exact location)
/way Northern Stranglethorn 72 33
First, you have to set the instance difficulty to Heroic (right click your portrait). This dungeon doesn't have a Normal mode, so you can't enter until you set the difficulty to Heroic.
There are two elites mini-bosses in Zul'gurub that you can kill and drop volatiles every time:
- Florawing Hive Queen drops [Hive Queen's Honeycomb], which contains 4-6 x [Volatile Life] and 4-6 x [Volatile Air].
- Tor-Tun drops 5-8 x [Volatile Earth].
Don't kill any other bosses or you can't reset the instance!
After you killed one of these bosses or both of them, you can go outside and reset the instance by right-clicking over your own portrait then click the "Reset all instance" button. This restarts the whole instance and all mobs will be back. You can only do 10 instance runs in an hour, so you will have to wait a bit since one runs usually won't take longer than 2 minutes and you will hit the instance cap in like 20 minutes.
If you are too low level to solo Vortex Pinnacle, you can farm Scion of Al'Akir. There is a lot of them at Uldum and they respawn very quickly. The drop rate is not that great, around a 12%.
If you are an Engineer, you can farm Volatile Air with [Electrostatic Condenser], but only if you have a gathering profession.
IMPORTANT! If you are level 120, you will see the patch 8.3 version of Uldum. You can talk to Zidormi to switch between the new and old low-level phase of Uldum. (if you open the map, she will be marked with a white text bubble at Ramkahen)
