Basic Blade Mistress Information:
Character level (Clvl) is an assessment of how far your character has progressed in the various skills, for each level you gain in a skill your character level is raised a fraction, but increase one skill a lot or several skills a little and you will gain a character level. Once you pass certain character levels you can also increase your Character Age.
Aside from being a prestige thing each character level you gain increases your health (HP) by one point, so being a Clvl 20 fighter means that you have 25% more health than when you started and so are a more effective fighter. Gaining Clvls also allows non-fighters a better chance of survival in combat.
So how exactly is character level calculated?
