Li feels the pain as the fiend claws his throat and growls. His expansion only has a few seconds left, and he knows it. Once it fades the beast will have an advantage. He reaches up to rip the clawed hand away from his throat with one arm, while shooting the other out to slam the fiend's head into the wall via its neck. If sucessful he will use the impact to put a little distance between them.
