Terra Blade

The Terra Blade is currently the most powerful Sword in the game, even stronger than Tizona. It shares its damage with the slower Chlorophyte Warhammer. With the right items equipped, it does 187 damage. It shoots a green sword forward in a line when used, which can hit multiple targets. If a flask is buffing the character, the ranged attack will also apply the flask effect to all enemies that it hits. Also the green blade that it shoots can hit up to three enemies.

Trivia
The blade is named after the land of Terraria which already comes from the Latin word "terra", meaning "earth." So considering the Night's Edge is evil/corrupt, and Excalibur is good/hallowed, they could neutralize each other.
