The Genlock conjurer is a powerful variation of genlock emissaries.
It can be found in the great hall on the first floor of Fort Drakon. The Conjurer summons a small group of shades, lead by a Greater shade. After taking enough melee damage, it will turn invisible and then re-appear at the other end of the hall. It is advisable to use ranged weapons against this enemy rather than trying melee, or eliminate the shades first.
