Bag of Necessity

The Right Thing At the exact moment a specific item is truly needed, a small brass key appears at the bearer’s feet. Using the key as a bonus action, you unlock the bag and retrieve the needed item. The bag then reseals and cannot be accessed again until the next time the condition is met. No Voluntary Access The bag is sealed at all times and cannot be opened, forced, or magically penetrated except by the manifested key at the GM-determined moment. You cannot choose what it provides, store items in it, or check its contents. Key-Tell When the key appears, it lands with a clear metallic ping and faint warm glint. Until the end of your next turn, you have disadvantage on Dexterity (Stealth) checks to avoid being noticed due to the sound and light.
