In the rule “Engaging in a Duel” add the following text:

There is a publicly-tracked number named Hourglass which defaults to the number of non-Idle Wizards. Whenever the Battle Master receives a spell selection for a Duel or a request to clear a spell selection for a Duel, the Battle Master should update the Hourglass with the number of Wizards who do not have a spell selected for the Duel that is currently Open.

If it has been at least 24 hours since the last Duel was Resolved, the Battle Master should post a reminder message in the #current-dynasty Discord channel containing the current Hourglass value and optionally the names of Wizards who have not yet submitted a spell selection for the Duel that is currently Open. The Battle Master should repeat this process every 24 hours and may choose to do so more often after the first 24 hours since the last Duel was Resolved.

In the rule “Commencing a Duel” add this bullet point just before the very last bullet point:

* Set the Hourglass to the number of non-Idle wizards.
