In Rule 2.6 (Lights), replace the “Attack a named Guest” bullet point with:-

• Kill a named Guest (known as the Target) that they share a room with. Only a Murderer may take this Dark Action, and a Dark List may contain only one Kill action. Upon taking this Action, if the Target is present in the same room as the Murderer, the Target becomes Dead. Either way, everyone in the room (except the attacker and the Target) Glimpses the attacker.
• Wound a named Guest (known as the Target) that they share a room with. Only a Murderer may take this Dark Action, and a Dark List may contain only one Wound action. Upon taking this Action, if the Target is present in the same room as the Murderer, the Target becomes Wounded. Otherwise, the attack attempt makes a Crashing Noise in that room.
• Handcuff a named Guest (known as the Target) that they share a room with. Only a Detective may take this Dark Action, and a Dark List may contain only one Handcuff action. Upon taking this Action, if the Target is present in the same room as the Detective, the Target becomes Restrained. Otherwise, the handcuffing attempt makes a Clicking Noise in that room.

And add a paragraph to the rule:-

Whenever a Kill action results in other Guests Glimpsing an attacker, the Executor shall select the Role of six random Guests (from those who were not the attacker), and privately share that same list - plus the Role of the attacker - with each Guest who Glimpsed it.
