In the end, Jake recovered his katana when it got back to normal, and the enemy also pulled the longsword from his back. He got serious damage from those attacks, and he was bleeding, but the lich wasn't done yet. He also grabbed the sword as if he was planning to use it like one… it wasn' time for that kind of taunt or words, but the lich felt like he should give Jake some words for whatever reason. Probably out of anger.
"I will make you all pay…" The lich said.
"Vengeance never gets old as a motivation, huh," Jake said. "I came here to finish this quest, but I was starting to wonder if I should since some humans did you some wrongdoings. However, considering that you are this unreasonable, then I don't have any other choice. I will put you down and force you to answer my questions."
