Final Phantasm.

The atmosphere turned eerie dark, and Leonard froze mid-flight. The trees stopped moving, and the howling of the wind quieted down. Dave was stuck in position. He didn't know what was happening.

Thunder struck, and the sky tore open, revealing a black object that came crashing down into the ground right next to Dave.

This object was quite familiar to Dave. It was Nick's Skull-Themed electric guitar. One of the guitar strings strung a high note. And from the guitar, an enormous wave of death magic burst out and surged across the Wilds.

The area of 100-meter radius around the guitar began decaying. The trees withered and died, and the grass became dry then turned to dust. From all around Dave, death energy infested the forest, killing anything that had life in it.
