The subject of this article or section is part of Midsummer Fire Festival, a seasonal event that lasts two weeks. Once the event has run its course, this will no longer be available until next year, but there are no guarantees.
Skar'this the Summoner is hostile naga that spawns only in the Slave Pens during Midsummer Fire Festival. As adventurers show up, he can be seen using the Ice Stone to summon Lord Ahune. He was added in the 2010 Level 80 Version of Midsummer Fire Festival. He drops no particular loot, and enjoys to repeatedly cast Frostbolt.
How DARE you! You will not stop the coming of Lord Ahune!
At any other time of year Skar'this can be found as caged Skar'this the Heretic further in the Slave Pens.
His weapon model is recent, further indicating his addition is a recent idea by Blizzard.
