"To make an Illusion Technique look convincing enough, you must mix in a bit of reality," Alamir said with a smile, explaining to Bruto, "Kalalin is absolutely a genius, he combined high-level illusion with the Fireball Technique to create this incredibly effective Red Dragon Illusion Technique. Not to mention an average-intelligence White Dragon, had I not known in advance, I wouldn't have been able to tell it was fake immediately."
Just as the Elf Priest had said, most creatures in the Dragon's Nest believed it to be real, at least the White Dragon was convinced it had really been attacked. Caught off guard at first, it immediately summoned a massive chill to extinguish the flames created by the Red Dragon's 'Breath', then flapped its wings and took to the sky, unleashing a cold Dragon Breath at the illusion of the Red Dragon.
