Summoners are hostile mobs found exclusively within the Dimensional Passageway. Summoners have the ability to summon mobs such as wolves, minotaurs, and dragon warriors to fight beside them. They can also teleport a fleeing player right in front of them, making these a dangerous foe if not confronted early.
Curiously, when first encountered, each Summoner will say "So, you finally came...?" as if expecting the player all along.
