Spatial Magic was incredibly rare, and also difficult to master.
Due to its rarity, not too many Spells related to it existed. Even among said Spells, not too many were high-level.
The Skill: Black Hole, fell under the territory of Spatial Magic.
However, since it consumed a lot of Mana, and it was an uncontrollable force that would only stop if the Mana of its caster ran out, it was placed at B-Tier.
[Singularity Point] was the A-Tier version of the Skill, but it was also very difficult to use.
With the S-Tier [Absolute Spatial Magic] Skill, it was possible to make Black Holes.
However, they were just as unstable and impractical as the lower-tier Skills.
There were simply more efficient ways to use Spatial Magic—even for destruction—other than Black Hole.
But…
An exception could be said to exist.
