This guide will show you how to farm and acquire the rare item, Essence of the Breeze. The item will make you able to jump a bit longer and a wind swishy thing will trail behind you when you jump.
A rare mob named Ai-Ran the Shifting Cloud will drop the Essence. It has a 20% drop chance. Ai-Ran will respawn about every 2 hours, so you might end up farming him for a while. The location of Ai-Ran is marked on the map below.
Like other Mists of Pandaria rare mobs, Ai-Ran has 3 special attacks. These are useful to know in order to kill him.
1 – Chi Burst – Stay within 15 yards of Ai-Ran to avoid damage.
2 – Healing Mists – Huge heal. Interrupt if you can
3 – Spinning Crane Kick- Stun him. Or Kite to avoid.
Since the droprate is 20% on the Essence of the Breeze, it is a bit quicker to farm than most other MoP rare drops. I usually park an alt where Ai-Ran spawns and just log in from time to time to see if he is there. Good luck!
