Bury the Light

Bury the Light is a Hardmode accessory found in the Champion Chest in the Underworld domain. As long as the player uses a weapon, the sword will automatically attack enemies within a 36 block range. The damage of the sword will be multiplied by damage bonuses from all classes.

It is a unique accessory in that it's name is displayed as shaking, light-veiled text. This being one of two items displayed this way, the other being the Storm Wings.
