A large explosion happened, and Uvish's body trembled a little. At the same time, the targetted head exploded, and then the neck fell to the ground. Still, the neck soon regenerated, and Uvish started to attack again…
"At least it didn't split in two while regenerating…" Billy thought.
While he was dodging those attacks, Billy considered his options… he could make some clones and make them get the mana from that world before it explodes since Uvish's attacks were increasing the mana levels from there. He also could try to create an opening and then open a portal inside of the enemy's body and use his own attacks to explode everything… Billy's real body probably won't survive that. Those were the only things Billy could think of in that situation…
