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 three targets. Like the True Night's Edge and the True Excalibur, it cannot be swung continuously. If a flask is buffing the character, the ranged attack will also apply the flask effect to all enemies that it hits.

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. The Terra Blade actually does less damage than Paladin's Hammer
