Reign vs the Elephant
"Hahahahahahah, even with your strength you won't be able to defeat me now!" Bone said as he was already creating a plan to escape this place. He knew that even with the elephant, the chances of him defeating Reign were almost none existent. Even though it pained him to do so, he had to sacrifice the elephant in order to escape from this place and slowly gather his strength back.
'Even though it's an incredibly powerful monster, I have no other choice than to do this.' Being forced to sacrifice the strongest monster he had managed to fully control was not something he wished to do since it was one of the trump cards he had. Nobody in the group knew about it, just like they didn't know about how he can merge his ability with the skills and change them.
