Zeratul needed a dark archon to destroy the warped crystals, as only its psychic fury was capable of it. It was accompanied by several other heroes in the mission. The Dark Archon Hero can use its Mind Control ability to bolster the strike force's strength.
Prevents allbiological units (friendly included) within a 4 x 4 area from attacking, moving, or casting spells for short period of time.[1] Stunned cloaked units will be revealed. Burrowed units will not be revealed or stunned.
Transfers control of any enemy unit to the casting player. Using Mind Control will drain the dark archon's shields and leave it vulnerable.[1]
Mind controlling a transport will also transfer control of any units the transport is carrying, and mind controlling a unit that has researched upgrades or special abilities will transfer them to the dark archon's player.
The transfer is permanent and irreversible, even after the death or the transfer of control of the dark archon who performed it. Any unit can be subject to multiple Mind Control spells, effectively changing ownership every time.
