You say, 'Hail, Himart Kichith'
Himart Kichith says 'Greetings young one, I am Himart Kichith, shaman of the Scaled Mystics and storekeeper of valuable knowledge of the past. I am always looking for knowledge of the past in the form of spells and [rare scrolls]. If you are interested in a tidy profit perhaps you would be willing to help me.'
You say, 'what rare scrolls?'
Himart Kichith says 'The remaining scrolls are very rare indeed. Very few have surfaced over the past few years. Should you happen to find more than you can use, return one of them to me and I shall grant you even more power. I still seek the Talisman of Jasinth, Spirit of Scale, Cripple, and the third rank of Cannibalize.'

He can return either of the following spells, it is random: Insidious Decay, Talisman of Shadoo, Shroud of Spirits or Torrent of Poison.

If you have one of the 3 or 4 50+ NPC drop shaman spells that this guy asks for and you either don't want it or have 2 trade it in for a different 50+ spell. I got Spirit of Scale and decided to trade it for the hell of it. I got the group disease resist spell for it. I was hoping for Bane of Nife :)
