The Damage Core plugin enables you to have full control over the damage calculation process of your game ranging from individual damage formulas to damage caps to damage calculation steps.
Introduction
Please wait while you are redirected...or Click Here if you do not want to wait.
The game gives a lot of control over the damage formula, but it doesn’t give much control for everything else after calculating the damage formula. This plugin will give you control over the order the damage fomrula is calculated in addition to letting you insert your own changes to the damage formula at whatever you you wish.
If you have YEP_BattleEngineCore.js installed, place this plugin under YEP_BattleEngineCore.js if you wish to make use of the extra features this plugin has to offer.
Notetags
The following are some notetags you can use to modify the damage caps.
Skill and Item Notetag:
<Bypass Damage Cap>
This causes the skill/item to ignore the damage cap and go with the regular value of the calculated damage. This will cancel out any damage cap effects otherwise. This will take priority over any damage cap breaking effects.
Actor, Class, Enemy, Weapon, Armor, and State Notetags:
<Bypass Damage Cap>
This will cause the related battler to bypass any damage capping effects and its skills/items will go with the uncapped calculated value.
<Damage Cap: x>
<Heal Cap: x>
This will set the skill to have a damage/healing cap of x. This will cancel out any damage cap bypassers. If a battler has more than one damage cap, it will go with the highest value. This means if an actor that has a weapon that brings the damage cap to 99,999 and an accessory that brings the damage cap to 999,999, then the battler’s damage cap will be the highest value of 999,999.
Plugin Commands
The following are plugins you can use to set the damage cap rulings for your game. Keep in mind that individual aspects such as equipment traits, skill properties, etc. will take priority over these default caps.
Plugin Command:
SetDamageCap 9999
Sets the default damage cap to 9999.
SetHealingCap 9999
Sets the default healing cap to 9999.
EnableDamageCap
Enables default cap for both damage and healing.
DisableDamageCap
Disables default cap for both damage and healing.
Lunatic Mode – Damage Formula
For those who think the damage formula box is too small and would like to use the notebox instead to declare the damage formula, you can use the notetags below:
Skill and Item Notetags:
<damage formula>
value = 500;
value += 2500;
</damage formula>
This will overwrite the damage formula found at the top and use the strings in the middle as the formula instead. Keep in mind that using comments here will cancel out anything following after. New variables can be used, too, to make damage calculations a bit easier.
value – Refers to the amount that will become the base damage value.
user – Refers to the actor/enemy using the skill/item.
subject – Refers to the actor/enemy using the skill/item.
target – Refers to the target actor/enemy on the receiving end of the skill/item.
Lunatic Mode – Damage Steps
The damage formula isn’t all there is to calculating the damage that appears at the very end. In this plugin’s parameters towards the bottom, you’ll see a large list of Damage Steps. Each one of these steps is a line of code that the damage count will run through in order to calculate and finalize the damage output.
The purpose of those parameters is to allow you ease of access on where you want to insert code that is your own or custom code provided by another plugin. Here’s a quick reference on how the original damage flow looked like:
Game_Action.prototype.makeDamageValue = function(target, critical) {
var item = this.item();
var baseDamage = this.evalDamageFormula(target);
var value = baseDamage * this.calcElementRate(target);
if (this.isPhysical()) {
value *= target.pdr;
}
if (this.isMagical()) {
value *= target.mdr;
}
if (baseDamage < 0) {
value *= target.rec;
}
if (critical) {
value = this.applyCritical(value);
}
value = this.applyVariance(value, item.damage.variance);
value = this.applyGuard(value, target);
value = Math.round(value);
return value;
};
In the vein of keeping everything organized, the following lines have been incorporated into new functions:
Formula New Function
value *= target.pdr value = this.applyPhysicalRate
value *= target.mdr value = this.applyMagicalRate
value *= target.rec value = this.applyHealRate
value = this.applyCritical(value) value = this.applyCriticalRate
Yanfly Engine Plugins – Battle Engine Extension – Action Sequence Commands
If you have YEP_BattleEngineCore.js installed with this plugin located underneath it in the Plugin Manager, you can make use of these extra damage related action sequences.
BYPASS DAMAGE CAP
– – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – –
This will override all damage caps. This is applied to healing, too.

Usage Example: bypass damage cap
DAMAGE CAP: x
HEALING CAP: x
– – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – –
This sets the action’s damage cap to x, overriding all over damage caps in play except its own. This will also apply to healing, too.

DAMAGE RATE: x%
DAMAGE RATE: x.y
DAMAGE RATE: VARIABLE x
– – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – –
This changes the damage rate across all types of damage (physical, magical, and certain hit). The damage rate is reset at the end of each action sequence. If you use a variable, it is treated as a percentage.
