Main Parameters

Main Resources
Health Points (HP) is the base parameter that will keep the character alive. When this reaches 0, the character dies. By default, HP is considered being critical when at 25% or less from its maximum value.

Mind Points (MP) is your main resource for skill usage. However, the lower your MP left, the greater magic damage you will receive up to a 25% extra damage at 0 MP.

Meta is a resource all characters generate during battle. It will fill your lack of MP and, by default, it will never surpass your maximum MP. This resource is very helpful because it allows you to keep using skills even when you're running out of MP.

Core Parameters
There are six core parameters that directly influence basic characteristics:

Strength (STR) mainly influences the damage output of skills and basic attack. Together with Weapon Attack, they are the two parameters that you need to increase if you want to deal more damage. It doesn't matter how much STR or Attack you're getting, it will always be more effective if you raise both.

Vitality (VIT) is your main defensive core parameter. It increases HP by 0.5% per each vitality point while also increasing the effectiveness of potions the character consumes. It also grants a soft defense bonus, where damage received is decreased by your vitality points. This makes vitality very useful for defense during the early game but not so much for the late game, where the player might rely more on Armor Protection.

Wisdom (WIS) is your core magic parameter, used mainly to increase magic damage (or healing) inflicted upon a target. It will also increase MP by 0.5% per point and increase the effect of potions that regenerate MP that are consumed by the character. It also grants a soft magic defense against magic attacks.

Technique (TEC) slightly influences attack but not as much as STR or Attack. It also increases your Critical%, Counter% and Hit%.

Agility (AGI) mainly influences when your character is going to act next in the turn order. The faster your character is, the sooner it will act. It also increases Eva% and Double Attack%. Bear in mind that Double Attack% only influences normal attacks.

Luck (LUK) influences many secondary effects. For starters, it will increase Critical Damage bonus, which by default is 40%. It also increases or decreases the chances of inflicting Debuffs or Ailments on the enemy, as long as your luck is higher than the target's. It will also grant you the chance of inflicting a free critical or Lucky Critical once every few hits. Furthermore, luck also increases the damage variability to your favor. For example, most attacks have a variance of 20%, this means by that default, any attack can deal from 80% to 120% its damage value. One point of luck would change that range from 81% to 121%.
