"It is another of those rare battle runestones," Peniel informed. "Like your Runestone of Spellcasting and Haon's Runestone of Combat, it can help you during combat."

"It's… a bit complicated," Peniel replied. "If you can master it, you will be stronger with that runestone active. That said, I imagine it will be rather difficult for you to master this runestone."

"Huh, why?" Jack asked.

"Give it a try, and you will understand," Peniel answered.

Jack rolled his eyes at his fairy companion. She still had her penchant for withholding information.
