LoreThe great Vizjerei Summoner, Horazon, made his lair beneath the sands of Lut Gholein. Seeing Demons as deceptive and cunning adversaries who deserved to be enslaved and tormented, he honed his abilities to control them as completely as possible. His prowess as a powerful Summoner is well documented, but Horazon secretly feared that the Lords of Hell would punish him for enslaving their brethren. The creation of his Arcane Sanctuary was an attempt to keep opposing mages, inquisitive thieves and even lesser Demons confused and far from his summoning circle.

Tips and Other Additional Information
You will know you've found the Summoner when taller Fire Walls and Glacial Spikes start bombarding you. The Summoner is a very powerful spellcaster and resistances (especially Fire Resistance) help a lot against him. His life is fairly low so avoid any projectiles he throws at you so you can rush him. If there are monsters blocking your path to the Summoner's platform, lead them away before killing them so he can't get free hits on you.
