In the final encounter, two Incarcerator Hydras, one on each side of the arena, must be destroyed to summon Conduit Minotaurs. Killing a Conduit Minotaur leaves an Arc pool that grants the Arctrician buff, which is used to complete the Arc circuits that lock Persys inside the reactor core for the reactor purge.
