To the Knife action, add “Knifing is Fast.” To the Double-Back action, add “Doubling Back is Fast.”

Add a new Street Action:-

Block (specifying another Assassin as the Threat): if the Assassin has a Position and shares that Position with the Threat, and if the Threat has not had any Notes processed during the current Tolling, then the Threat’s Notes are removed from the Note sequence and the Threat is privately informed that they were blocked by the Assassin who took this action. Blocking is Fast.

In the rule “Notes”, replace “The Notes are arranged in a random sequence.” with:-

The Notes are arranged in order, starting with those that included a Fast Street Action and no Urchin Action (in a random order) followed by all other Notes (in a random order).
