Zan-Tien Lasso

Zan-Tien Lasso drops from mogu in the Vale of Eternal Blossoms (level 120 version) during any invasion.

It is used on the Ivory Cloud Serpent to acquire the Ivory Cloud Serpent mount.

Acquiring the mount
Farm mogu in the Vale of Eternal Blossoms, regardless of which invasion is active, until the Zan-Tien Lasso drops.

During the Warring Clans invasion, head to, roughly 30 yards above the treetops. The Ivory Cloud Serpent spawns in roughly that location every two hours or so and flies at 310% speed in the direction of the Gate of the Setting Sun. The serpent will stop moving as soon as a player starts a channel, and will despawn 10 seconds later. It is entirely possible for a raid group of players spamming the macro to acquire the mount from the same spawn.

In order to actually acquire the item, players must use the lasso on the serpent.

Bind this macro to an easily-spammable button:

/stopmacro [channeling:Catching] /cleartarget /tar Ivory Cloud Serpent /use Zan-Tien Lasso
