Battlement Bow

This magic bow is enchanted with passive abjuration protections. When you hit a creature with a ranged attack using this bow, the bow creates a thin barrier of protective magic that stays between you and that creature until the start of your next turn. If you hit a different creature while protected by this barrier, the barrier moves to defend you against the new target instead. While the barrier is protecting you against a creature in this way, you’re considered to have half cover against that creature’s ranged attacks and spell effects.
