Wraiths with Locus of Resurrection, which allow them to be summoned at a target location, can be summoned in many places, some of which are off the map or outside of the playable area.
This led to a hilarious situation in the Lagon story fight, where casting Summon Wraith behind or to the side of Lagon (off the platform where the player stands) causes Lagon to turn around and face the Wraiths. This means the player does not have to deal with the claw smashes, lightning breath, etc. and makes the fight hilariously trivial.
No fear effects were used, and Lagon continued to attack, he just faced the Wraiths instead of facing me, which meant that I didn’t have to deal with most of the danger.
