Grain still couldn't see what or who he was up against.
Only barely avoiding any contact with several oncoming attacks.
None of the attacks were made of mana, at least a kind of mana he could absorb or convert. This meant he had to physically avoid each attack.
The one time he failed to avoid one of them, he had been smashed against the wall by something dense and hard.
The strike was so fast and powerful, that he couldn't even discern the shape of what hit him. Only that it sent shockwaves of pain through his body and knocked the wind out of him.
Before he could regain his composure, he was assaulted by half a dozen more attacks. Barely managing to avoid enough of them to make his way towards the ceiling.
Opting to keep his back up to the roof of the corridor, he hoped that if the attacks can only come from one direction, he would be able to handle them better.
