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 and the Well Fed and Tipsy buffs, it can inflict up to 289 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. The best prefix for Terra Blade is Legendary

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 crafting materials for this blade True Excalibur and True Night's Edge could be a reference to totality. Since Excalibur represents light and Hallow, and Night's Edge represents dark and Corruption (Crimson), the Terra Blade could be the equivalency of both sides.
