Abyssal Toll… I had gained this unique skill when I had cracked the frozen space that the Arcanist had held me with. In desperation, I had given the Hollow Avatar the freedom to push its emptiness deeper into my body, and it had done so, touching a part of myself that I had no access to.
This action had triggered the Demon Slayer Title in a way that I could not describe, but it had sent out a sound that was eerily similar to the foghorn from the Pyramid, and all thirty kilometres of the Pyramid had vibrated.
I had died before I saw the effect of this skill, but I could suspect what it did.
Unique meant one of a kind. It meant the system had no category for what I had done, no existing framework to file it under, so it had invented one on the spot. The same way it had invented Welded for my soul condition when the Hollow Avatar and I became inseparable.
I focused on the skill.
