With an effective way to turn enemies into living bombs (although the timing was a bit iffy sometimes) John was able to conserve his mana and have a blast testing his newfound physical capabilities. When he had gone for mindless jogs before (which still hadn't paid off) he had only thought about the end result. Actually using his Strength was satisfying. If Frank ever bothered him again, John could punish Dickinson for being a dick. A grimly satisfying thought and a short-lived one. He had greater things to worry about than his bully in a school he no longer cared about.
Aclysia culled the last Treant, just as John, with half his mana regenerated, felt confident enough to use a Mana Ray to bring a similarly quick end to the last Sporeling. He breathed in once, rolled his neck to relax a bit and waited for the familiar message.
