Damage Formula's description

0x11:

Prepare Function 0x0 (calculate physical hit chance)

Prepare Function 0x2 (calculate critical chance)

Damage Function 0x1

0xA0:

Prepare Function 0x0 (calculate physical hit chance)

Prepare Function 0x2 (calculate critical chance)

Damage Function 0x1

damage = damage * (1 + number_of_status1 + 2 * number_of_status2).

number_of_status1 are calculated as sum of attacker statuses darkness, slow, silence, sadness, poison, near death.

number_of_status2 are calculated as sum of attacker statuses death sentence, slow-numb.

0xA1:

Prepare Function 0x0 (calculate physical hit chance)

Prepare Function 0x2 (calculate critical chance)

Damage Function 0x1

if current hp less then max hp / 4 then damage = damage * 2.

if attacker in death sentence then damage = damage * 4.

0xA2:

Prepare Function 0x0 (calculate physical hit chance)

Prepare Function 0x2 (calculate critical chance)

Damage Function 0x1

damage = damage * (1 + number_of_dead_player_units).

0xA3:

Prepare Function 0x0 (calculate physical hit chance)

Prepare Function 0x2 (calculate critical chance)

power_modifier = total_level_of_all_enemy_target / number_of_enemy_target.

(this only use enemy units from 4 to 10 that includes in target mask after all preparation)

Damage Function 0x1

0xA4:

Prepare Function 0x0 (calculate physical hit chance)

Prepare Function 0x2 (calculate critical chance)

power_modifier = 1 + (((current_hp * 3) / max_hp) * power_modifier).

Damage Function 0x1

0xA5:

Prepare Function 0x0 (calculate physical hit chance)

Prepare Function 0x2 (calculate critical chance)

power_modifier = 1 + (((current_mp * 3) / max_mp) * power_modifier).

Damage Function 0x1

0xA6:

Prepare Function 0x0 (calculate physical hit chance)

Prepare Function 0x2 (calculate critical chance)

power_modifier = 1 + (((total_ap / 10000) * power_modifier) / 16).

(total_ap is no more than ap needed for max star, so underwater materia won't work)

Damage Function 0x1

0xA7:

Prepare Function 0x0 (calculate physical hit chance)

Prepare Function 0x2 (calculate critical chance)

power_modifier = 10 + (((number_of_kills / 128) * power_modifier) / 16).

Damage Function 0x1

0xA8:

Prepare Function 0x0 (calculate physical hit chance)

Prepare Function 0x2 (calculate critical chance)

power_modifier = 1 + (((limit_bar_value * (limit_level + 1) / 16) * power_modifier) / 16).

Damage Function 0x1

Damage Calculations

For standard damage functions

X0:

Sets Target's 02h flag to 1. (Unknown effect)

---

X1:

If Attack Property "Always Critical" is Set

Set Critical Damage Flag

End If

x = ( Actor's Level * Actor's (M)Attack ) / 32

y = ( Actor's Level + Actor's (M)Attack ) / 32

z = Actor's (M)Attack + ( x * y )

z = z * ( 512 - target's defense ) * Attack's Power

Damage = z / 4096

If Critical Damage Flag is set

Damage = Damage * 2

End If

Long_Range = 1

End If

Else

Long_Range = 0

End If

If Long_Range != 0

Damage = Damage / 2

End If

End If

If Target's Back is exposed

Damage = Damage * ( Target's Back Attack Modifier / 8 )

End If

X2:

multiNoSplit = ( ( ( Attack's Target Flags AND Ch ) - 4 ) == 0 ? 1 : 0 )

Base = (Actor's Attack + Actor's Level) * 6

Damage = (512 - Target's Defense) * Base * Attack's Power

Damage = Sadness( Damage )

Damage = Barrier( Damage )

Damage = Variance( Damage )

---

X3:

If Attack Properties Damage MP is clear

Damage = Target's HP

Else

Damage = Target's MP

End If

Damage = Damage * Attack's Power / 32

If ActionData[AC] != 0 (?)

Damage = Damage / 2

End If

Damage

---

X4:

If Attack Properties Damage MP is clear

Damage = Target's MHP

Else

Damage = Target's MMP

End If

Damage = Damage * Attack's Power / 32

If ActionData[AC] != 0 (?)

Damage = Damage / 2

End If

Damage

X5:

Damage = (Actor's (M)Attack + Actor's Level) * 6 + (Attack's Power * 22)

Damage = SplitDamage( Damage )

Damage = Barrier( Damage )

Damage = Variance( Damage )

---

X6:

Damage = Attack's Power * 20

---

X7:

Damage = ( ( 512 - Target's Def ) * Attack's Power / 32 )

Damage = Variance( Damage )

---

X8:

If ActionData[0x230] AND 40h

ActionData[0x230] = 1

Else

ActionData[0x230] = 80h

End If

---

X9:

Actor's Attack = Actor's Strength * 2

Use Damage X1 with adjusted stat

---

XA: Damage = ( Attack's Power + Number of Targets - 1 ) / Number of Targets

---

Sadness( Damage ):

If Target's Status includes Sadness

Damage = Damage - (Damage * 3 / 10)

End If

Return Damage

---

SplitDamage( Damage, multiNoSplit ):

If multiNoSplit == 0

If No. of Attack's Targets >= 2

Set Attack's split damage Target Flag

Else

Set multiNoSplit == 1

End If

End If

If ActionData[0xAC] == 0

Damage = Damage / 2

Else

If multiNoSplit == 0

Damage = Damage * 3 / 2

End If

End If

Return Damage

Barrier( Damage ):

If Attack Property "Physical" is 0

If Target's Statuses include MBarrier

Set ActionData "MBarrier Active" flag

End If

Else

If Target's Statuses include Barrier

Set ActionData "Barrier Active" flag

End If

End If

If ActionData "MBarrier Active" or "Barrier Active" flags are set

Damage = Damage / 2

End If

If attack is Magic and EnabledMagic[7] == 0 (?)

Damage = Damage + ( Damage * ( EnabledMagic[7] * (10 / 32) ) / 100 )

End If

Return Damage

Variance( Damage ):

Damage = Damage ([0..255] + 3841) / 4096 //from RNGLUT in KERNEL.BIN

If Damage == 0

Damage == 1

End If

Return Damage
