The tesseract monolith is an advanced variant of the khaydarin monolith enhanced with xel'naga technology. In an alternate timeline where Zeratul survived the beginning of the End War, the dark prelate utilized them to fight Amon's Forces. With the aid of the artifact fragments, Zeratul could summon them on the field, allowing them to stun his enemies.[1]
Tesseract monoliths are the static defensive option for Zeratul in Co-op Missions. They serve as a calldown option once Zeratul has found the first artifact fragment. Tesseract monoliths deal low damage, but stun enemies in an area for a short time. When summoned, tesseract monoliths are permanent. With artifact fragments they can be upgraded to protect themselves with a Shade Barrier and relocate their weapons and shields for 60 second with Shade Projection. They are called down from the top bar, can store three charges, and each charge has a 180-second cooldown.
Projects the Tesseract Monolith to a target location for 60 seconds, transferring all of its shields and its weapon. The Tesseract Monolith is deactivated while this ability is active.
