In Terraria, you can obtain Ghost Wings by defeating the Empress of Light, a boss that can be found in the Hallow biome. After defeating her during the day, she will drop the Ghost Wings as one of her loot items. These wings allow you to fly and glide, providing a significant advantage in exploration and combat.
