Blood Channeler

From the Lore Book
The Blood Channeler softens up opponents by removing its mask and projecting magical energy from the huge vortex in its chest. Then it wades in to finish them off with its enormous twin blades. Channelers are often seen operating back-to-back on the battlefield, sowing chaos and weaving an ever-growing wave of magical destruction.

A Titan Golem from the Arcanum Gudanna.
