Trivia

The Bestiary entry for the Astral Probe: "What were once simply common birds have been transmuted by the overwhelming amounts of mana. Though weak on their own, they choose to harass those who are unassimilated while the victim attempts to fight off other infected beasts."

There used to be variants of the astral probe spawned by Astrum Deus during its fight.
