Low Success Rate

"Cough!" Krune coughed out blood as he felt difficulty in breathing. The impact was way too powerful for him to handle. On top of that, when he crashed into a couple of bone trees, some of the sharper objects managed to penetrate his defenses, lodging into his body. 

Gritting his teeth in pain, Krune hurriedly pulled out all the bone tree fragments in his body, quickly inspecting himself as he soon heaved a sigh in relief. He had pulled all of them out in time. Though, when he looked at a piece of the bone tree fragment, noticing the roots that had formed on it, he shuddered in fear. 

If he had been a couple of seconds late, the bone tree fragment would have lodged itself in his body. The only way to remove it would have been to cut a part of his body out and hope he would survive long enough until he finished healing. 

Ocean Heart!
