The four arrows—each associated with a season—that accompany this bow can be fired only from it. Each arrow disappears immediately after it's used, and it reappears in the quiver at the next dusk. The save DC against spells cast with the arrows is 18.
As an action, you can fire this arrow at an unoccupied space on the ground that you can see within 320 feet of you, no attack roll required. A Nyxborn lynx is summoned in that space (use the stat block for a tiger with the Nyxborn traits from chapter 6). The lynx understands your verbal commands and obeys them as best it can, and it takes its turns immediately after yours. The emissary remains for 1 hour before fading away.
