Delete the text “Each Agent also has a privately tracked variable called Loot, which may be any positive integer and defaults to 0.” from Guards and Burglars.

Replace the rule Valuables with:

There is a list of Artifacts that currently exist. All artifacts have a publicly tracked name, which is one of the listed items on [[Souveniers]] and which is not shared with any current artifacts. When the artifact is created, its creator (normally the Concierge), must select a name from that list to be its name, and it must be unique with respect to all artifacts on the list of Artifacts. That name is flavour text. In the event that any artifacts share a name, it is permissible for any player to append numerical digits onto one of those names such that it becomes unique, and that is considered a valid name.

All artifacts have up to one publicly tracked artifact trait, defaulting to no trait.

All artifacts have a privately tracked Location which is either a spot, or the name of a player, or blank, and all artifacts a publicly tracked Home, which is a spot. The Home is said to contain that artifact, but this is not necessarily true. If the Location is the name of a player, that player is said to be holding that artifact. If the Location is ever simultaneously the name of an Agent and the name of a spot, then that Agent is not said to be holding that artifact.

If there are no Artifacts, the Concierge may take the atomic action titled “Scattering Valuables” which is as follows:

*Secretly randomly determine a number between 2 and 4 inclusive.
*Add that many artifacts to the list of artifacts, choosing an appropriate name for them as described in the rule Valuables
*Select a spot for each new artifact, and set the Home and Location to that selected Spot for that artifact.
**Selected Spots may not be any Spots which contained artifacts immediately prior to the previous Breaking In action.
**Selected Spots may not be any Spots which are listed as Points of Ingress, nor may they be adjacent to any such Spots, and they may not be the Grounds.
*For each of those artifacts, give them a privately randomly selected trait from the artifact trait list, excluding any traits which are already held by at least one artifact in the list of artifacts

The list of Artifact traits and their effects are found in the table below.

Artifact Trait | Effect
Mundane | -
Alarmed | When an Artifact with this trait has its Location changed to the name of a Burglar, any Guards in Spots connected to that Burglar’s Location Encounter that Burglar
Concealed | Artifacts with this trait have three Homes. When an Artifact gains this trait, the Concierge should select two more Homes for it such that each of those Homes is connected to at least one other of this Artifact’s Homes. Then, its Location should be set to one of its Homes.
Disguised | Burglars without Observant cannot hold an Artifact with this trait. If such an artifact would have its location set to that Burglar’s name, it instead does not have its location changed.
Rare | When a Burglar gains Infamy during the Breaking In action, if they are holding an artifact with this trait, they gain an additional 2 infamy.

In the rule The Break-In, replace the bullet point starting “For each Burglar who is the only Agent at a Spot which contains an Artifact” with:

For each Burglar who is the only Agent at a Spot which contains an Artifact, set that Artifact’s location to be that Burglar’s name.

In the same rule, replace “plus 4 for each point of Loot they currently have” with:

plus 4 for every artifact they are holding.

In the same rule, replace the bullet point starting “If any Burglar who Encountered no guards” with:

If any Burglar who Encountered no Guards during this atomic action is holding at least one Artifact, increase the Successes of all Burglars by one; otherwise, increase the Successes of all Guards by 1.

In the same rule, remove the text “, and set all Agent’s Loot to 0.”

In the same rule, replace the bullet point starting “Remove all Spots” with:

Remove all Artifacts from the list of Artifacts, then perform the “Scattering Valuables” atomic action.
