Failures

As the dozen Shadow Soldiers engaged Magnus, Vale seized the opportunity to get closer to the old man's shadow, setting his plan into motion.

"Cursed Flame!" Magnus exclaimed. 

He then pressed his hands together, and soon, the black flames coalesced and began swirling, eventually expanding to engulf all of the Shadow Soldiers at once.

Boom!

The sheer force behind the strike shattered the castle's windows, leaving a visible crack on the pillars and walls.

Magnus was going all out!

However, to Magnus's surprise, the Shadow Soldiers endured for more than 10 seconds, demonstrating remarkable resilience.

They seemed protected by an unknown force he couldn't identify.

Nevertheless, it only delayed the inevitable. The Shadow Soldiers perished after some time.

Then, at the same time, Magnus's Cursed Flame Spell duration had also ended, rendering him unable to utilize the Spell for a period of time.
