Soul Hook
As soon as Klaus re-entered his soul sea, he was greeted by the sight of a terrifying red eye with red runes spinning around it. The moment his gaze met the red eye, his vision blurred for a few moments before he regained clarity.
"What the fuck was that?" Klaus muttered, shaking his head.
"Seriously, why can't anything in my soul sea show some care and gentleness when they're trying to bless me with something?" Although he complained, a small smile tugged at his lips.
The blackout he had just experienced wasn't a bad thing—in fact, it was good. He had received a technique from the red eye, and judging by its nature, it was exactly what he desperately needed.
During the battle with the zombies, Klaus used the Eye of Despair along with his Eye of Malevolence to launch a soul attack that killed a Zombie Prince.
