The immortals possessed an absurd number of unique spells.
Fire Seal.
Water Seal.
Wind Seal.
Lightning Seal.
Earth Seal.
There were also rarer variants, shadow seal, metal seal, ice seal, poison seal, storm seal, and many more. At their core, they were simply combinations and refinements of the original elemental seals, but once layered with laws and intent, they became terrifyingly effective.
And those were merely the base forms. Each seal had countless variants branching from it.
For example, the Fire Release used by Albert, or the Earthly Disintegration spell once displayed by City Lord Brown.
Grey, in particular, was fond of Earthly Disintegration. The way it collapsed matter from within, bypassing surface defenses, made it exceptionally lethal.
Unfortunately, due to the urgency of conquering the southern region, he hadn't stayed long enough to observe it properly.
He should ask City Lord Brown to use it again later. Just once would be enough.
