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

Comienza localizando el manejo de las entradas de efectos de ailment de la pestaña config y la lógica de validación o conversión de valores que utiliza. Confirma cómo los campos de brittle y de los demás ailments rechazan actualmente los decimales y, a continuación, verifica que los valores decimales como 2.6 se acepten y conserven en cada campo relevante.
