Complaining won't do. It is not as if the arena spirit will intervene in the fight if he complains enough. It will be foolish to expect that to happen. So he concentrated on his dilemma and took stock of his situation.
He watched the dragon try to stand as he muttered. "It is strong. It is fast. It can fly. It can control world power. It can use dragon fire. Its defense is too strong. It is a dragon but it doesn't have a dragon scale. It is meant to be unkillable. At least, I can't kill it unless I get more power."
He began to list out what he discovered about the dragon and it isn't good news. He detonated that phantom spear for two things. The most important one is to evade the claw attack. His previous brush with it made him realize that the dragon's claws can shred him if they get a good hit on him.
