This plugin extends the functionality of the difficulty selection plugin
created by Ozumi Tsuno.
Place it below the plugin in the Plugin Manager.

Distributed by: http://tm.lucky-duet.com/viewtopic.php?t=430

Stores the current difficulty level as a variable/switch.
This allows you to create Enemies skills that are only active on
specific difficulty levels, and by incorporating the difficulty variable
into calculations, you can create skills whose power varies depending on
the difficulty level.

Furthermore, you can change weakness and resistance multipliers depending
on the difficulty level.
For example, if the weakness multiplier is set to 2.0, a 1.1x weak
attribute will become 2.2x.

This plugin does not have plugin commands.

@help 尾角 つの様作成の難易度選択プラグインの機能を拡張します。
プラグイン管理画面で同プラグインより下に配置してください。

配布元：http://tm.lucky-duet.com/viewtopic.php?t=430

現在の難易度を変数・スイッチに格納します。
これにより、特定の難易度でのみ有効になる敵キャラのスキル等が
実現できたり、難易度変数を計算式に組み込むことで、難易度によって威力の変動する
スキルが作成できます。

さらに、難易度によって弱点・耐性倍率を変えられるようになります。
弱点倍率を2.0に設定した難易度の場合、1.1倍の弱点属性が2.2倍になります。

このプラグインにはプラグインコマンドはありません。

利用規約：
 作者に無断で改変、再配布が可能で、利用形態（商用、18禁利用等）
 についても制限はありません。
 このプラグインはもうあなたのものです。
