I had been wondering if Enchanted Items didn't kind of suck compared to potions, which are much more flexible. Then when reading the Enchanted Item rules for about the third time, I _finally_ noticed that last sentence.
When a practitoner has already used all the 'uses per day' for an item, they can continue to use it by taking one mental stress for each extra use. Gah! That makes enchanted items about fifty times more useful. This is especially nice if you're someone with Ritual or Thaumaturgy but not Evocation and aren't using that mental stress for anything else when not doing ritual casting. Get yourself a nice Enhanted Item weapon and go to town. Even for a full wizard, I can see a lot of situations where it would come in handy.
Am I the only one to have not noticed that rule on the first read-through? Right now I'm feeling kind of dumb for having dismissed enchanted items.
