Investigation rules

Bathing makes mysteries available again but does not replenish their limited rewards. Unless a reward is marked as shared across locations, repeat limits apply separately to each mystery. Only the roll results or victories specified in its reward row count toward that limit; other results do not.

A mixed draw grants one random blessing or one random curse, with a 50% chance of either. See How investigations work for the general rules and die display.
