Version: 1.0.1
If an attack has multiple attributes, all of the attack's attributes are used
in damage calculation.

The calculation method differs between Shiro-san and additive.
For example, if you use a fire + light attack on an enemy with 200% fire
effectiveness and 150% light effectiveness,
the result will be as follows:
Multiplication: 2 x 1.5 = 300%
Addition: 2 + 1.5 = 350%

Please note that in additive mode, if you use a fire + light attack on an
enemy with 100% fire effectiveness and 100% light effectiveness,
the damage will be 1 + 1 = 200%.

@param addition
@text Add or
@desc Whether to add the effectiveness of all attributes when calculating. If OFF, they will be multiplied.
@type boolean
@default false

version: 1.0.1
攻撃に付与されている属性が複数ある場合、
その攻撃の属性すべてをダメージ計算に使用します。

城さんと加算で計算方法が異なります。
例えば、火＋光属性の攻撃を、火有効度200％ 光有効度150％の敵に使用すると
以下のようになります。
乗算の場合: 2 x 1.5 = 300％
加算の場合: 2 + 1.5 = 350％

加算の場合、火有効度100％かつ光有効度100％の敵に火＋光属性攻撃を行うと
1 + 1 = 200％となってしまうことに注意してください。
