Hunting monsters IV

CLAP! As the girls were arguing mid-fight they hear a loud bang coming from the forest.

"What was that? Lightning?" Mary said looking at the sky, It was a bit cloudy but she couldn't expect thunder. The could weren't dark or anything, she could even doubt it will rain.

"That must be Cain, it's that spell of his!" Sofia said as she finished her slime off with [Firebolt] "I don't remember it being this loud though."

"This is a spell? But if it can be heard from here it must be a strong one." Mary asked as she looked toward the forest, would Cain be okay inside the forest?

"It's supposed to be third-tier and it's quite impressive," Sofia said as she collected the core. since she used magic the core wasn't damaged.
