Earth Elemental - "Allow me to introduce myself, my name is Korg"
This is just a simple Weakaura that plays Korg's introduction from Thor: Ragnarok when a shamans Earth Elemental is summoned.
To use this Weakaura, you will need SharedMedia from curse forge

It's noteable that it doesn't just work for the caster, anyone with this WeakAura can hear Korg when an Earth Elemental is summoned regardless of class/group/etc
If you're unfamiliar with how to use SharedMedia there's a great youtube tutorial here: https://www.youtube.com/watch?v=GEbGgREGZ34
