Ever wanted to make a skill that deals more damage each time it’s used in battle based on the number of spells cast? The skill would deal a small bit of damage at the beginning of battle and end up quite big towards the end of it based on the total number of spells cast per battle. Here’s how we can make this effect in RPG Maker MV!

Insert the following code into your skill’s notebox. Change the values to reflect your game’s settings.
<Damage Formula>
// Default the number of times it's been casted to 0
var total = user._totalSpellsCasted || 0;
// The multiplier used based on the number of times it's been used.
var bonusMultiplier = total * 0.50;
// The damage formula with reference to the multiplier bonus
value = user.mat * (1 + bonusMultiplier);
</Damage Formula>

// The passive state linked to this skill
<Passive State: 319>
Insert the following code into your passive state’s notebox.
<Custom Battle Effect>
// At the start of battle reset the number of casts
user._totalSpellsCasted = 0;
</Custom Battle Effect>

<Custom Action Start Effect>
// Default the amount of spells casted to 0
user._totalSpellsCasted = user._totalSpellsCasted || 0;
// Get the user's current action
var action = user.currentAction();
// Check if it is a skill and magical
if (action.isSkill() && action.isMagical()) {
  // Increase the total number of spells casted by 1
  user._totalSpellsCasted += 1;
</Custom Action Start Effect>
