Without wasting time, the shadowy figure made his zombies ignore Efreet and run toward Leon. No matter what happens, he couldn't let him finish that spell. Although combining darkness with any other element was supposed to be impossible given the properties of that kind of magic, Leon managed to do it. The theory behind it was relatively simple. Leon just had created a sphere of darkness that had the same gravitational power as a Black Hole. However, since it wasn't a spell per se, he could control to some extent what he could absorb, and right now, he wanted only to absorb other sources of dark magic.
The more the zombies approached, the bigger the dark-reddish sun became. However, as expected, with Leon's current skills, there was a limit of how much mana he could absorb, so several zombies managed to jump over that small sun. However, they were stopped by a massive wall of earth.
"Thanks, Gnome," Leon said. "But try to consume less mana next time."
"You got it!" Gnome said.
