If the quantity isn't specified, does that mean the items are available in a single copy?

And I think I should have more experience after the first act (including the medallion).

In Boreas, they are reusable. In Sails, they are single-use. In Magograd, they are single-use except for Pururuta. In Toska, they are reusable. In Wind, they are reusable.
