In the rule “Diving for Treasure”, before the subrule “Treasure” add a subrule named “Artifacts” with the following text:

An Artifact has a Name, a Use, and an Effect. Each Fishing Contestant has a publicly-tracked Artifacts, which is a list containing 0 or more Artifacts, defaulting to an empty list.

If the Use of an Artifact contains an Action, a Fishing Contestant who has that Artifact in their Artifacts may perform that Action to apply the Effect of that Artifact. If the Use of an Artifact contains a Condition, every Fishing Contestant who satisfies that Condition and has that Artifact in their Artifacts must have that Artifact’s Effect applied to them by the Fishing Contestant or Elder Judge who performed the dynastic action that triggered the Condition. When the Effect of an Artifact is applied to a Fishing Contestant, as part of applying the Effect that Artifact must be removed from the Artifacts of that Fishing Contestant.

In the subrule “Treasures”, add the following text:

When a Fishing Contestant who performs Diving for Treasure gets a result of Treasure, they select the row from the table below where their Depth is within the numerical range of the Treasure Result column of that row, and then apply the Effect on that row to themselves:
