Battle Formulas

• Hit Determination
• Evasion Determination
• Critical Hit Determination
• Damage Calculation
• Preemptive Strikes and Surprise Attacks
• Escape Success Rate

RPGVX's default battle system uses the following formulas.

The active battler is represented by A, where the battler who is the target for A's actions is represented by B.

Hit Determination

Normal Attacks

If A is an actor

Hit rate (%) = Hit rate of the weapon equipped by A

• If they are unarmed, it will be 95.

If A is an enemy character

Hit rate (%) = A's hit rate

Skills

Hit rate (%) = the skill's success rate

Items

Hit rate (%) = 100

• When the attack is a physical one and A has a [Reduced Hit Rate] state added to him, the hit rate will be 1/4 the normal rate.
• The messages displayed during a miss are as follows:
  • If the attack was physical, the message will be "Miss! *** was not damaged!"
  • For other types of attacks, "There was no effect on ***!" will be displayed.

Evasion Determination

If B is an actor

Evasion rate (%) = 5 + the evasion rate of the armor equipped by B

If B is an enemy character

Evasion rate (%) = B's evasion rate

• If it is not a physical attack, the evasion rate is treated as 0%.
• If B has the [Cannot Act or Evade] state, his evasion rate will also be 0%.
• The message displayed for a successful evasion is "*** evaded the attack!"

Critical Hit Determination

If A is an actor

Critical hit rate (%) = 4

• If the [Frequent Critical] option is enabled, 4% will be added to the critical hit rate.
• If a [Frequent Critical] weapon is equipped, 4% will be added to the critical hit rate.

If A is an actor

Critical hit rate (%) = 0

• If the [Critical Exists] option is enabled, this will be 10%.

• This is only determined for normal attacks.

Damage Calculation

Normal Attacks

Damage = A's attack × 4 - B's defense × 2

• If the results of the calculations would be a negative number, it will be made 0.

Skills/Items

If the base damage is a positive number

Damage	=	Base Damage
	+	(A's attack × 4 × Attack F ÷ 100)
	+	(A's spirit × 2 × Spirit F ÷ 100)
	-	(B's defense × 2 × Attack F ÷ 100)
	-	(B's spirit × 1 × Spirit F ÷ 100)

• If the results of the calculations would be a negative number, it will be made 0.

If the base damage is a negative number

Damage	=	Base Damage
	-	(A's attack × 4 × Attack F ÷ 100)
	-	(A's spirit × 2 × Spirit F ÷ 100)

• Of the attributes that accompany this action, the largest of B's attribute effectiveness values is used to modify the result.
  A:200%, B:150%, C:100%, D:50%, E:0%, F:-100%
  However, if B's armor or state has the [Halve Attributes] effect, these values will be halved.
  If there are multiple such effects, they will all be taken into account.
• If the normal attack damage would be 0 after attribute effects have been taken into account, there is a 50% chance that the attack will still cause 1 damage.
• A critical hit multiplies the damage caused by 3.
• If B is defending himself, the damage will be cut in half. If he has a strong defense, the damage will be 1/4 the normal amount.
• Damage amounts are random to some extent, as determined by the dispersion settings.

Preemptive Strikes and Surprise Attacks

If the average of the actors' initiatives >= the average of the enemy characters' initiatives

Preemptive strike rate (%) = 5

Surprise attack rate (%) = 3

If the average of the actors' initiatives < the average of the enemy characters' initiatives

Preemptive strike rate (%) = 3

Surprise attack rate (%) = 5

• In the case of a preemptive strike, the enemy characters cannot act for the first turn.
• In the case of a surprise attack, the actors cannot act for the first turn.
• Preemptive strikes and surprise attacks do not occur for event battles.

Escape Success Rate

• 10% will be added for each failed escape attempt.
• During a preemptive strike, the actors will always be able to escape.
