Is your feature request related to a problem?

In the config tab, the "effect of ailment" fields do not allow you to input decimals, restricting you to whole numbers.

Describe the solution you'd like

I'd like to be able to specify a decimal rather than being limited to whole numbers. This is mostly relevant for brittle, but might as well do it for the others too.

Ex: Being able to input 2.6 "effect of brittle" instead of having to round to 2 or 3

まず、config タブの ailment 効果の入力処理と、それが使用する検証または値変換ロジックを特定します。現在 brittle フィールドやその他の ailment フィールドが小数をどのように拒否しているかを確認し、そのうえで 2.6 のような小数値が関連する各フィールドで受け入れられ、保持されることを検証します。
