Evaluation
"Losing to a ghost, how dreadful... You know what else is dreadful? Betraying me... The Spirit Girl uses mostly Fire and Pleasure attacks. Also, be careful because she can use an instant death attack. She has elemental resistances common to all ghost type monsters. She has high physical evasion and is weak to Fire. Now go, oh Brave Luka. Send that ghost into the next world."
