That trick was old at that point in time. Jason punched the spears with his Barrage of Blows, pushed the enemy away, and even kicked him on the side. But soon, his chin began to burn… attacking unprotected areas wasn't a good idea.
The boss slime looked at Jason with a serious expression on his face. Jason had gotten a lot stronger than he had assumed he would be, but it made sense considering how many bosses he had faced until now.
Before the enemy had the chance to think of a new strategy, Jason charged toward him and enveloped his weapon with wind magic. The boss jumped away and fired some Acid Spheres at him, but he blew them away with his punches. Moreover, thanks to the wind magic, the acid splashed away from Jason.
