Hekkal had just found his footing on the Lion's Mane Hog's turbulently moving upper ass when he felt Micah get close. He only had enough time to react and look up before the heavy iron wrench crashed into the side of his face.
Micah swung the wrench with all the force he could muster, and he nearly stumbled because of that. He had just absorbed a large amount of pol in one go, and he wasn't yet used to the strength dwelling in his body. So, if he wasn't careful, he could accidentally throw himself off the hog. His unstable control over his strength atop the wildly sprinting hog was a recipe for disaster.
But Micah couldn't afford to be overly cautious just because he might lose his balance.
