"[Heatwave Illusion]."
That was the Spell that Ash used to turn the tide of the entire battle to his favor.
This was, of course, a high-level Spell that followed the same principle as the illusions or mirages caused by an actual Heat Wave.
In cases of severe heat, it is possible for images to be distorted through the bending of light which then creates a blurred effect. However, this is only a small part of the illusion, as it relies on too many external factors and can only produce very simple illusions.
The second and most effective aspect of the illusion is caused by inducing the target itself with such severe heat that it affects their brains, hence their perception of reality through their optical lenses.
In essence… completely fooling their senses through the power of severe heat.
