Hearing the words of the Old Lich, Aleister immediately felt a strong relief.
The Aura of Fear from Matthias was so potent that it could even penetrate the protection of the Night Fiend... even though Matthias himself was only a Transcendent of the Fifth Power Level.
Even if the occupation of a Lich in the current version is like that of a Great Sin Scholar, a "hidden occupation," it should not be possible to leap over two power levels and breach the resilience of a Superior Phantom of the Sixth Power Level, such as the Night Fiend.
This means that such a powerful augmentation could only come from the outside—meaning, he must have equipment that grants him priority.
To put it more plainly, it is the Spirit Summoning Tower itself.
As the true Master of the Spirit Summoning Tower, Matthias would certainly have access to part of the tower's power. And at the core of the tower is the spine of the Spirit Amber Celestial Marshal.
