Apocryphal Harbinger Hostile to 2nd Player in IA

xencthlu

During the infinite archive, if you get the Apocrypha Emissary vision 3 times, you acquire the Apocryphal Harbinger. One of the abilities of the Apocryphal Harbinger is that it can summon two copies of itself. If you're running IA in a duo, these copies will be hostile to the player who doesn't have the vision. I have been able to attack these multiplied Harbingers, which means they can absorb attacks intended for actual enemies. I don't know what other abilities the copies have, if they have attacks that can then be used on me.
