William launched his new technique multiple times in the past few minutes, killing lots of the dark and normal masters at the same time. Then the entire battlefield changed, with around twenty dark masters being a bit stronger than early-stage dark gold grade.
William knew his flying weapons wouldn't be able to take them down. As for his two monstrous weapons, they could take a few of them, at the cost of consuming most of their spirit powers in less than half an hour.
He didn't hesitate to issue them the order to take any dark master near them as soon as they got the chance to. As for him, he switched gears, and returned to using his first technique, stacking attacks over his tails, before releasing them against targets one by one.
*Boom!* *Boom!* *Boom!*
