Asura was annoyed as he missed so much but the closer he got the more accurate he got. Some of the bone shards hit, but it was the stones he hurled that seemed to hurt more. Probably because he was applying Smash to them. He was gaining on Jason but it wasn't as fast as before, but still. Progress was progress. Those eyes littering his form seemed to get a joyful look with each time he struck the stone based slime.
Then he got a new skill. Throw Item I. Did that make him more accurate? He didn't care, he just continued to pick pebbles and stones up to launch them as hard as he could with Smash I. "You're on borrowed time, boy!" He roared as he shoved himself to go as fast as his body would let him go. Soon his body was eating at the stones, sharpening them while letting some remain blunt. Sharp disks of stone flew like frisbees, minus the arcing they normally did.
Asura was honestly surprised he hadn't been hit by a magical attack, nor by a System Message saying his Stamina was low. So he continued with his ravenous pace while also continuing to act like vacuum cleaner. Sucking up literally everything at this point. Sediments, algae, mold, lichen, rocks, twigs, insects. The sediments, plant life, and insects were pulverized by his acidic body. The stones were continued to be throw at a rapid pace. As it entered, he ate away at its surface to smooth it, before launching it with a wet crack.
