Ring
Uncommon Conjuration Requires Attunement
A thin golden ring with subtly engraved daggers on the inside.
When attuned, a creature can use a Bonus Action to conjure a spectral dagger +1 in the hand with the ring on it. These daggers are perfectly balanced and can be used as throwing daggers. The dagger will stay until dismissed (using no actions) or when it moves further than 40 ft away from the ring.
