Spiritcaller Dohgar has asked you to use the Orb Collecting Totem to collect 15 Razaani Light Orbs. Return to him at Mok'Nathal Village in the Blade's Edge Mountains after you have done so.
15x Razaani Light Orb collected
The Razaani ethereals have strange devices that emit small, pink floating light orbs. They remind me of souls.
They are not to be confused them with the large yellow balls that break free of the ethereal when they die, these are something else entirely.
I'd like for you to head north to Razaan's Landing and drop some totems, which will attact the pink light orbs.
Bring them back to me so that I might determine exactly what they are.
