Eventide

The Eventide is a Hardmode bow similar to the Chlorophyte Shotbow that consumes arrows, but fires streams of colorful rainbows. While only consuming a single arrow from the player's inventory per firing, 5 streams are fired, which can be spread out by moving the cursor while firing. Each stream can pierce up to four enemies. The Eventide has a chance of being dropped by the Empress of Light boss.
