The beast they killed was a Lightning-type beast. It wouldn't finish their quest, so they would have to keep hunting. But they still got their hands on a core that they could use to finish a mission later. They would just take a Lightning Magical Beast hunting mission and submit the Beast Core. That was generally what Marcus did for his Mercenary Quests.
