An illusionist uses their psychic power to make their enemy feel, see, hear or smell things that aren't really there. Everty illusion is dealt through the mind.
First-class illusionists can even kill their enemies with illusions; if the enemy believe that the illusion is real for even one second, they would be hurt by the illusion for real. The downside of this is that if the opponent know that it's not real, there is no effect on them.
Normal illusions take control of fear and force other people to be afraid.

When an illusionist use their illusionists combines with the Mist Flames, they can create Real illusions, and the illusion would be experienced in reality.
Sometimes it is hard to distinguish Real illusions from normal illusions. Real illusions, however, have the ability to hurt people without the fear or belief of reality that is needed when attacking with normal illusions.

In a battle between ilusionists, one need to have complete control of ones own mind, or one might be damaged by the opponents illusions. The first one that is unable to recover their control will lose, and they will be left to their opponents mercy.
