"Surprisingly everyone didn't run away from here. They fought the rapidly regenerating creature then moved as if it were circling this place with the collapsing realm portal as the center point."
One by one they gave brief reports as they destroyed tens to hundreds of undead creatures with multiple concentrated plasma blasts.
