Angel Level Relics often had extraordinarily complex properties. A single set of documentation could contain more information than the properties of ten Keeper of Secrets Level Relics. The Sword Spawn Mother Nest was like that. Shade spent five minutes using Rapid Reading just to go through the densely packed text once. The appendix contained even more than the documentation itself.
Back when the Bloodkin Gormora Clan had contained that sword for nearly a thousand years, they had conducted extremely thorough research on it. In general, its "Mother Nest Property" was the core power of this highly dangerous relic, while all its other properties could be considered extensions of that trait.

"I really didn't expect this. This relic's greatest weakness is actually spiritual and soul-based attacks. Who would think to use that kind of attack on a sword?"
After reading the documents, Shade could not help but sigh:
