Repeating his previous movement, Astaroth willed more mana to correlate around his balled-up fist. Upon contact with the wall, the glowing surface rippled again, this time more noticeably.
To verify if the strength of his attack varied the results, Astaroth simply apposed his hand on the wall, before infusing it with mana. This time, the result differed.
Instead of rippling, the wall this time seemed to bend inward almost like it was made of a taut fabric instead of stone.
Putting both hands on the glowing part of the wall, Astaroth pushed harder, infusing more and more mana into his hands, as the wall bent further inward with every ounce of extra mana.
At some point, he was halfway into the wall, with the surface still not giving in to him. Frustrated that his efforts weren't yielding more results, Astaroth gritted his teeth.
"Fine! You want to play hard to get? Then get a taste of this!"
