Terra Blade

Terra Blade is currently the most powerful sword (Although, it shares its damage with the slower Chlorophyte Warhammer) in the game on the PC version, even stronger than Tizona. With the right items equipped, it can have 176 base damage. It shoots a green sword forward in a line when used. If a flask is buffing the character, the ranged attack will also apply the flask effect to all enemies that it hits.

Crafting
One True Night's Edge, one True Excalibur and a Broken Hero Sword is required to craft the Terra Blade. Crafting the Terra Blade should be done at a Mythril Anvil.

Trivia
one of the mechanic's name is terra, this might make the reference to the sword
