Skiller Value

Skiller Values are the measurement of how effectively someone's body can channel and use Magi. They range from 1 to 100.

To reliably activate any CHARM (and thus, to be a Lily), one must have a Skiller Value of at least 50. There are certain CHARMs that require a higher Skiller Value than this, but one's Skiller Value doesn't affect the performance of the CHARM as long as they can activate it. Having a low Skiller Value also excludes one from developing certain Rare Skills and subskills.

Those who have low Skiller Values at a young age often see them increase as they grow older, with many girls' Skiller Values rising above the minimum of 50 by the time they enter high school. Because of this, many Gardens allow even girls who can't yet use CHARMs to enroll in their grade school and junior high school divisions, in the hopes that they will qualify to be Lilies.

However, a girl of high school age whose Skiller Value hasn't reached 50 has only three choices: she can become an Arsenal, a Madec, or give up on taking part in the war against the Huge and return to civilian life. Active Madecs are sometimes able to continue increasing their Skiller Values to the point where they can become full-fledged Lilies.

The highest Skiller Value of any active Lily is Tachihara Sayu's, at 98. According to Futagawa Fumi, if there existed someone with a higher number than this, it would in fact be dangerous; Sayu's is effectively the upper limit at which one can safely be a Lily.

Men have Skiller Values of 50 at most, and even the rare few who do are no longer trained to use CHARMs.
