Priority

Two rules can easily pick the same pair of players. When that happens only one of them applies: the one with the highest priority. The losing rule is not thrown away, it waits underneath, and the moment the winner stops applying it takes over on its own.

A rule takes its priority from the page it sits on. Right click the page, select Change Priority and set a number. When one entry on that page needs to differ, set its Priority Override field instead.

Writing an exception

With priority you can write "everyone, except these players". The classic case is vanished staff who still see each other.

You need two audiences for this: one holding the vanished players, one holding the staff. How you build those is up to your story. A Criteria Audience on a permanent fact works fine for both.

1. The broad rule

On a manifest page with priority 0, add a Hide Visibility Effect and a rule that uses it.

Add Visibility Rule

Change how selected players are rendered to selected viewers

+

Set the viewers to everyone and the targets to the audience of vanished players. Every online player now loses sight of everyone who is vanished, including the other staff.

2. The exception

Make a second manifest page and set its priority to 1. Add a Show Visibility Effect and a rule that uses it.

Add Show Visibility Effect

Renders the target normally, overriding lower priority effects

+

Set the viewers to the staff audience and the targets to the same vanished audience.

For a staff viewer both rules now match, and the one on the higher priority page wins, so staff see each other while everyone else sees nobody. When a staff member drops out of the staff audience, the hide rule underneath takes over immediately.

 Equal priorities

Two rules from different entries with the same priority for the same pair is almost always a mistake, since which one wins comes down to whichever was added last. Typewriter logs a warning naming both entries when this happens.

Stacking exceptions

Nothing stops you from going further. A third page with priority 2 and a Ghost Visibility Effect could show vanished staff as translucent to players who bought a spectator perk, while the priority 1 rule keeps them fully visible to staff and the priority 0 rule keeps them hidden from the rest of the server.

Keep the numbers spread out while you build. Jumping by tens instead of ones leaves room to slide a rule in between later without renumbering the pages around it.
