Beast Inheritor?

"Boss floor? So there is a boss to the dungeon?" asked Kims.

"I refuse to talk about the boss since I've got a plan for that, which I don't want you guys screwing up," stated Jack, getting Tralon to smile curiously at the hero. "If there's nothing else, then let's go already."

"Wait." Tralon held up his hand. "Since you don't want to talk about how you'll deal with him on the eleventh floor, I've got a question for you, Jack. What do you think will happen if you give a crane an inheritor's pact?"

Jack first squinted then showed a wild grin. "That's a great question to consider, isn't it? Let's try it!"

The cranes hadn't been stored away as they were the same size as Phoro and wouldn't attract much extra attention on the later floors. So, when the lead crane overheard the change in the conversation, he tilted his head and asked, 'What's a pact? And What does it do?'
