Version: 1.0.1
By entering the specified description in the memo field for an actor, job,
equipment, enemy character, or state,
you can add a feature that multiplies additional stats.
This multiplier is applied after applying any additive features you can
specify in the editor.

Example:
Halves evasion rate
<multiplyXParam:eva:50>

Doubles HP regeneration rate
<multiplyXParam:hrg:200>

Basic syntax:
<multiplyXParam:[param]:[value]>

[param]:
hit: Hit rate
eva: Evasion rate
cri: Critical hit rate
cev: Critical hit evasion rate
mev: Magic evasion rate
mrf: Magic reflection rate
cnt: Counterattack rate
hrg: HP regeneration rate
mrg: MP regeneration rate
trg: TP regeneration rate

The following plugins are required to use this plugin.
DarkPlasma_AllocateUniqueTraitDataId version:1.0.0
If using with the following plugins, add this below.

version: 1.0.1
アクター、職業、装備、敵キャラ、ステートのメモ欄に指定の記述を行うことで
追加能力値を乗算する特徴を追加します。
エディタで指定できる加算特徴を適用した後に、この倍率が適用されます。

記述例:
回避率半減
<multiplyXParam:eva:50>

HP再生率2倍
<multiplyXParam:hrg:200>

基本構文:
<multiplyXParam:[param]:[value]>

[param]:
  hit: 命中率
  eva: 回避率
  cri: 会心率
  cev: 会心回避率
  mev: 魔法回避率
  mrf: 魔法反射率
  cnt: 反撃率
  hrg: HP再生率
  mrg: MP再生率
  trg: TP再生率

本プラグインの利用には下記プラグインを必要とします。
DarkPlasma_AllocateUniqueTraitDataId version:1.0.0
下記プラグインと共に利用する場合、それよりも下に追加してください。
