To get The Invoker you'll have to have own the Buadren drum. Once you finish with getting your Buadren Aun Tikakhe mentions that Aulakhe may be able to enhance it once more. Talk to Aun Aulakhe who is next to the burning fire and he'll give you the Akiekie Ember. If you continue to talk to him he'll summon a portal right in the pond which is restricted to level 50+.

In order to complete this quest you'll need to have 4 different groups to pull levers. Inside the dungeon you'll find portals with 4 different level restrictions. Seperate into 4 teams and buff up. Lightning bane your armor. Only comment on this is run as fast as you can. The dungeon is pretty straight forward for the lowest group. My character was in the lowest group so I can't comment on what the other three groups have to go through. The portals from the 4 seperate teams goes to the same destination. It is safe on the other side of the portal. Give the Akiekie Ember to Aun Tanua and he'll give you a Burning Akiekie Ember in return. Take the Burning Akiekie Ember to Aun Aulakhe the give him the Buadren also. He'll then give you The Invoker. It's best to give the items when Aun Aulakhe isn't busy.
