To stop the enemies once and for all, Billy just increased the gravity around the head of the monsters. Thanks to that, as soon as they appeared, the heads of the salamanders were slammed against the floor, and that got them dizzy. It granted enough time for the others to attack the beasts without getting attacked back. Still, Billy wanted the effect to be powerful enough to make their heads crack in the impact, he had a long road ahead... He was making progress, but perhaps he had to use his head a bit more instead of relying on brute strength only.
"I feel like forging a bow with this knowledge will be a perfect way to stop all kinds of monsters…" Billy thought.
Since Billy had the knowledge, that was possible. To make gravity work, he just had to send a powerful wage of mana in a perfect area in all dimensions to make it work. With that in mind, hitting an enemy on the limbs would be the same as attaching lances to the limbs of the enemies.
