The physical weapon triangle is: Sword > Axe > Lance > Sword
The magical weapon triangle is: Anima > Light > Dark > Anima
(">" means is "good against")

Double Attack

Property	Calculations
Attack Speed	= Speed - (Weapon Weight - Constitution, take as 0 if negative) [Minimum is 0]

Double Attack if: (Attack Speed - enemy Attack Speed) >= 4

Damage

Property	Type	Calculations
Attack	Physical Light Brand (direct)	= Strength + [(Weapon might + Weapon triangle bonus) x Effective bonus] + Support bonus
	Light Brand (indirect) Runesword	= (Strength / 2) + [(Weapon might + Weapon triangle bonus) x Effective bonus] + Support bonus
	Magical	= Magic + [(Weapon might + Weapon triangle bonus) x Effective bonus] + Support bonus
Defence	Physical	= Defence + Support bonus + Terrain bonus
Defence	Magical Light Brand Runesword	= Resistance + Support bonus + Terrain bonus
Damage		= (Attack - enemy Defence) x Critical bonus

(For Reaver weapons, the Weapon triangle bonus is doubled for both weapons, except when facing another Reaver weapon)
(Reaver weapons are Swordreaver, Swordslayer, Lancereaver and Axereaver)

Avoid	= (Attack Speed x 2) + Luck + Support bonus + Terrain bonus
Staff accuracy	= 30 + (Magic x 5) + Skill
Staff avoid	= (Resistance x 5) + (Distance from enemy x 2)

Experience

Property	Calculation
Experience from doing damage	= [31 + (enemy's Level + enemy's Class bonus A) - (Level + Class bonus A)] / Class power
Experience from doing no damage	= 1
Experience from defeating (base)	= [(enemy's Level x enemy's Class power) + enemy's Class bonus B] - { [(Level x Class power) + Class bonus B] / Mode coefficient }
Experience from defeating enemy	= [Experience from doing damage + (Experience from defeating (base) + 20 + Boss bonus + Thief bonus, take as 0 if negative)] x Silencer bonus

Class power: 1 for Journeyman (1), Recruit (1), Pupil (1), Civilian, Pontifex and Entombed, 2 for Cleric, Soldier, Troubadour, Manakete (M), Manakete (F), Thief, Priest and Dancer, 5 for Demon King, 3 for everything else.
Class bonus A: 0 for non-promoted classes, 20 for promoted classes.
Class bonus B: 0 for non-promoted classes, 40 for Assassins, Rogues, Bishops and Valkyries, 60 for all other promoted classes.
Mode coefficient: Initially treat this value as being 1. If Experience from defeating (base) is calculated as 0 or negative, this value becomes 2 instead. For all other cases it remains 1.
Boss bonus: 40 if enemy is a boss, 0 if not.
Thief bonus: 20 if enemy is a Thief, Rogue or Assassin, 0 if not.
Silencer bonus: ~1.8 if the user activates Silencer, 1 if not.

Note: Experience from defeating enemy is rounded up if Mode coefficient is 2
