The attacks all hit the blood cocoon and an explosion took place. Compared to the one that Reign had previously created, this one was much more powerful. The explosion destroyed everything in a 600-meter radius, almost engulfing Reign and the others in it.
They were able to evade the explosion, but the shockwave from it blasted them away and dealt some damage to them as they slid on the ground for tens of meters after landing.
It wasn't just the sheer size of the explosion that was above Reign's, but the power as well. When Reign's lightning spear exploded, the area some 30 meters around it was destroyed, but the remaining 470 meters was simply filled with lightning arcs that dealt some minimal damage to the ground.
A person would have been fried inside that space, but for those that had reached Tier I, it would just damage their skin and that would be it. This explosion, however, would destroy most Tier I monsters as well.
