~IMPORTANT: If you are faced with a fraction or a decimal in doing these calculations, then ROUND DOWN.~

Attack Speed: When attacking, if your Constitution is less than than the Weight of the weapon you are holding, then your Attack Speed is (Your Constitution-Weapon's weight) + Your Speed.
If not, then your Attack Speed = Your Speed.
In a battle, the character with the highest Attack Speed takes action first.

2x Attacks: A unit will attack twice if it's Attack Speed is 4 or more above the other unit's attack speed. [Note: Dual Attacks can not be done to characters with 50HP and over]

Base Hit Rate: Weapon's Base Hit Rate + (Skill x 2) + (Luck / 2) = Your Base Hit Rate. Add 5 if you have an S-Rank for using the type of weapon you are attacking with.

Evasion Rate: (Attack Speed x 2) + Luck

Final Hit Rate: Your Base Hit Rate - Opponent's Evasion Rate

Base Critical Hit Rate: Weapon's Base Crit. Rate + (Skill / 2) = Your Base Critical Hit Rate. Add 5 if you have an S-Rank for using the type of weapon you are attacking with.

Critical Evasion Rate: Your Luck.

Final Critical Hit Rate: Your Critical Hit Rate - Opponent's Critical Evasion Rate

Damage: Attacking Unit's Attack or Magic (Strength/Magic + Weapon Might) - Defending Unit's Defence or Resistance = Damage Done

SPECIAL DAMAGE RULE: "Effective Against ______" Weapons: [(2 x Weapon’s Might) - Enemy Defense] + Unit’s Strength or Magic +/- 2 for Weapon Triangle Advantage or Disadvantage

Weapon Triangle: If you are the winner of the Weapon Triangle (fighting with a weapon that beats the other's weapon), then add 1 damage and 15% from your hit chance at the very end of calculations, *just* before rolling the RNG. If you are the loser, subtract 1 damage and 15% hit chance.

Reminder:
Sword bests Axe
Axe bests Lance
Lance bests Sword

Anima bests Light
Light bests Dark
Dark bests Anima

Remember if using a reaver weapon the triangle inverses. If two people are using a reaver weapon however it double inverses, and goes back to normal.
