[Soul Conduit].
The Attribute had no description, nor was its acquisition announced by the Spell. Staring at the runes for a few more seconds, Sunny cast one last glance at the white void of his Soul Sea and left it.
He had no answers for this mysterious sequence of events, but his intuition was ringing the alarm bell.
He was almost sure that the strange and painful process that began after he had absorbed the last shadow fragment was somehow interrupted. The white light permeating the Soul Sea felt unnatural and wrong, like something external to it rather than natural. The mysterious new Attribute was most likely connected to this external influence instead of to the saturation of the Shadow Core.
