The magic arrow that was supposed to miss its target did not stray from its path. It was the target that was sent back to its former location as time warped. The Coldburn Living Storm looked like it was reenacting the reverse of what it did earlier, but this is due to the Adrian rewinding its time.
Adrian looked tired as the amount of mana needed to rewind the time of the Coldburn Living Storm was five times its normal skill cast. It was a good thing that he was able to save some of his mana and not put it all in the magic arrow earlier. The magic arrow that was supposed to hit nothing has landed perfectly right inside the eye of the Coldburn Living Storm.
"Boom!" Adrian stated as a powerful explosion resounded.
