Downgrading Dice

To Downgrade a [Die] you simply replace the indicated [Die] in the [Pool] with the next [Die] as per the following progression system:

D4 < D6 < D8 < D10 < D12

If you have been granted a Downgrade but all of the [Die] in the [Pool] are already D4’s, then nothing happens. A [Die] cannot be Downgraded below D4.
