Delete the text of the rule “The Discrepancies [Prime]” and give it a new subrule called “Scanning” as follows:

Scanning is a Discrepant Action and an Atomic Action that can only be taken if at least one Portal is open, with the following steps, which all occur before the check to see if a new Portal is opened:

1. The Scientist who is Scanning (the Scanner) selects a single Portal in a Universe where they are present (the Scanned Portal) and rolls DICE13 in the Blognomic Dice Roller, naming the Scanned Portal and the Universe in question in the comment for that roll without naming any other Portals or Universes.
2. The Scanner then changes the Star Sign of the Scanned Portal in all Universes to match the Star Sign designated by that die roll, in order from the list in the rule “Star Signs [Prime]” with 1 being the first Star Sign so listed and 13 being No Star Sign.
3. If the Scanned Portal’s Star Sign would be set to No Star Sign, instead, its Strength is set to 0 in all Universes.
4. If the Scanner’s Star Sign matches the Scanned Portal’s Star Sign, then both the Upsider and the Downsider are moved to the Universe that is the Source of the Scanned Portal.
