Avoiding Death in Otome Game, I'll Have To Be Invincible

Power Levels:- There are three power levels for Practitioners;

Magic Users/Knight, Grand Mage/Grand Knight and Sage.

Most practitioners are either called magic users, magic knights or by other equivalent titles.

Grand Mage, Grand Knight or any title with 'Grand' is given to the people whose magic power capacity have surpassed normal humans. Grand mages are the leading figures throughout the world.

Sages are the highest level beings who have understood certain law of the world. Sages are rarely seen as most of them are either at the head of an organization or living in seclusion.

Mental Power:- The clear division of mental strength is also in three levels;

Spirit Lake, Spirit River and Spirit Sea.

They are further divided in stages which is especially applicable for Spirit Lake; lower, mid, high and final stages.

Most of the non practitioners remain in lower spirit lake level throughout their lives. Advancing in mental power is more difficult than in magic power.

Danger Level of Evil Magic Users:- these are not natural levels but humanly assigned ranks according to the threat. It's closely equivalent to the rank of the party required to subdue that threat.

Adventurer's rank:- these ranks are assigned by the adventurer's guild according to the accomplishment of the adventurer. Most rank 'A' adventurers are Grand Mage or equivalent in strength.

Magic Core:- these are concentrated cores of energy that are formed inside strong magic beasts and monsters after their death.

Humans and some other intelligent species can absorb these magic cores to gain the ability of those magic beasts.

Normal Pratictioners can only absorb a single magic core throughout their lives. Grand Mage can absorb a second magic core and sage can absorb a third.

To absorb even the weakest magic core, the person requires at least 'mid' spirit lake level mental strength. The stronger the magic core is, higher the mental strength requires to absorb it.

Kai's current level:- Right now he is only a magic user but he has already absorbed a strong magic core and gained the ability to create small storms. His mental strength is also at the peak of spirit lake level.
