RegenerateVariance.js

You can set the variance of HP, MP, and TP auto-recovery, as well as damage.
The variance is set between 0 and 100, just like skill variance.

This plugin requires the base plugin "PluginCommonBase.js."
"PluginCommonBase.js" is located in the following folder under the RPG Maker
MZ installation folder:

dlc/BasicResources/plugins/official

You may modify and redistribute this plugin without permission, and there are
no restrictions on its use (commercial, 18+, etc.).
This plugin is now yours.

@help RegenerateVariance.js

HPやMP,TPの自動回復、ダメージ量の分散度を設定できます。
分散度はスキルの分散度と同様、0から100の間で設定します。
