Lukas was tired, even his dulled senses couldn't ignore his exhaustion. The pain in his back had only grown, even as his senses continued declining. He, Kai, and Cary had fought for the last five to ten minutes. Lukas couldn't be sure anymore, for all he knew they could've been fighting for half an hour by now.
What he knew was he was in pain, he was exhausted, and they had made zero progress. By now, its hind legs had regrown, they hadn't made so much as a scratch on its torso, and all they'd done was exhaust their energy and resources.
