The spear crossed the dark sphere and eventually reached Zenis. He didn't have time to react to that because of the distance and all the power Billy infused on it. Before long, a massive explosion happened in the sky, and Billy was pushed backward.
Billy was almost used to getting his back almost smashed against the ground by now, so when he landed, he just grunted without complaining. At the same time, he quickly used his domain to absorb the mana around… he was certain that Zenis wasn't going to die after that. Still, he was certain that he got some damage, finally.
Since Billy had to throw his glaive as well for the effect of his domain to take place, he looked for it around. The explosion of the dark sphere could have destroyed the weapon, but Billy didn't believe in that, considering how much mana he had put on it.
