Create a new rule named “Distiming” with the following text:

Any Gostak at the Distimmery may Distim a Dosh. To do this, e rolls DICEX+Y+Z where X is the number of number of Gostaks at the Distimmery, Y is the number times e has Distimmed a Dosh that day, and Z is the number of Shiny Demons. After doing so, e gains one unit of Distimmed Dosh.

The Shiny Demons do not like the Gostaks and their attempts to Distim Doshes. If the result of the dice roll required to Distim is greater than Quorum, then a Shiny Demon appears. The number of Shiny Demons is listed in the GNDT under Shiny Demons in the Distimmed Dosh column.

Name floor 18 “The Distimmery”

And finally, add a row named “Shiny Demons” and a column named “Distimmed Dosh”
