Nico activates the Staff of One using a word or phrase to invoke a specific spell. However, the same word or phrase cannot be used again, causing either a random magical effect or nothing at all to occur. So for example while Nico can cast healing spells repeatedly, she must think of a new word or phrase to focus the spell each time.
