Imagination Interface System:

Is a system unique and almost "perfect" of balance for all the players of the world. Any vocation or level determined.

Only if you are worthy. Probability 1%
The interface imagination system was designed to alter the parameters of the players in order to make a "perfect realism" to the Underworld.

Explanation: In the time that you have been inside the underworld, ou will understand that the world is not moved by simple numbers, you can check the system control rights. The right of system control is related to magic, skills and the "lost sacred arts", with a low level you can only use simple spells but if you level up you learn to use more complicated ones thats just like a normal game. The most important thing is this system that there was neither in Catlina nor in SAO. Imagination affects your parameters, if you trust that you can win, your power multiplies. That is, if you think you are stronger than anyone, it becomes possible to rewrite the laws of the world.
