I had two abilities that could make me stronger: Ero Boost and Berserk Wolf. If I used Ero Boost and its effect wore off in the middle of the fight, I'd be left vulnerable to another attack. And if I used Berserk Wolf, it would consume all my mana, and I wouldn't have control over my actions—I might even strike his club and lose my sword. Those two skills, as powerful as they were, should only be used as a last resort.
If I wanted to deal damage to him, I would need to get close enough and strike him with one of the skills I got from Sarah. And the opening would come when he made another serve.
The Hobgoblin resumed his tennis, this time tossing the stone to his side, high enough that he had to jump again. It looked like a normal serve, and I was already shifting my position.
My plan was to pretend to go one way, make a feint, and then dash toward him, catching him off guard.
