Cage of Folly
Once you have used the birdcage 5 times, the bird sings a mocking song for 1 hour when you fail an Arcana, History, Nature, or Religion check. If you open the birdcage and let the bird go free, it gives you one piece of good advice about a current problem or question that you face. At the Narrator’s discretion, the advice may give you _advantage_ on one ability check made in the next week. Afterward it flies away as the birdcage loses its magic and becomes a mundane item (though some who have released their birds claim to have encountered them again in the wilds later).
