Retains its original name after taming. This spectral devilsaur can only be found when the event, "Worldsoul Memory: Primal Predators" is up, located roughly north-west of Opportunity Point in The Ringing Deeps. The zone in which the Worldsoul Memory is active rotates daily, starting with Isle of Dorn, then The Ringing Depths, then Hallowfall, finally Azj-Kahet. You require one Radiant Echo in order to enter the event phase and cannot use another player to access it.
Level scaling: Most NPCs will scale with the Hunter's level, within the constraints of their level range. Hunters can tame regular NPCs up to 2 levels higher than them, but can only tame elite NPCs of the hunter's level or below.
