Hello folks, populating top comments from the other db site:

Myself and friends just got this achievement this morning - Tzhaa *Kazzak* Xíó *Stormscale* Rexit *Stormscale* Nocni *Stormscale* Combustylulz *Stormscale* (EU)

The rats are a lootable critter like NPC on the path between killing curator and Aran
There are only 5 in total so make sure you don't miss one! - 1 in the middle with the caster mob, 1 on the right path that leads nowhere and 1 in the corridor to medivh to name 3 locations.
You need to kill the mana devourer boss whilst mounted on this. However, do not do things like Shapeshift (impossible to do as guardian druid for example as you can't use bear form) and don't use leap abilities like infernal strike etc as these despawn the mounts.

 

Use the item before entering combat - you can cast whilst moving while mounted on them. (the items also are removed if you leave the instance) although, they do respawn if the instance is reset.
