Add a subrule titled “Sanity” to the rule “Explorers”. Give it the following text:

If an Explorer’s Sanity is less than 3 at any time, they involuntarily drop all held Items including Cursed Items, and their Ploy and Planned Action becomes “Rest” and cannot be changed until their Sanity is 3 or greater.

Replace this text in the rule “Explorer Actions”

Resting has no current effect.

with this text:

Resting adds 1 to the acting Explorer’s Sanity if the value is not already 10. Otherwise, it has no effect.
