Create a new rule “Danger!” in the ruleset for Faction BLO:

Lots of things are dangerous by nature like, for example, riding a poorly maintained merry-go-around or attacking polar bears with your bare hands. Because of this, some actions which a Citizen can take have a measurable element of Danger to it.

If an action is declared by a rule to be X% Dangerous, then the Citizen performing that action must roll DICE100 in the GNDT before taking the action. If the result of the roll is smaller than X, that Citizen breaks 1DICEY bones, where Y is the number of Dangerous actions taken that day by the Citizen. If the result of the roll is equal or greater than X, the Citizen has a lot of fun performing the action and is free to brag about how dangerous it was, even if other Citizens do not want to hear about it.
