There are 3 types of secrets from the teller or secrets.
Murdane Secrets are secret chests and locations.
Secrets of Stars are locations of blodstones or starstones.
And Secrets of Trade are locations of skillbooks. It may seem trivial, but couple of skillbooks are unique and only found this way. Although usually it should be easy to spot those skillbooks since they are all pre-placed on the ground.
