Terra Blade

The Terra Blade is a Hardmode sword. Before the 1.3 update, it had the highest base damage per hit of any sword. This title now belongs to the Meowmere. It auto-swings (except in the console version), firing a Blue bolt projectile that costs no Mana or ammunition and can pierce up to two enemies, dissipating upon impacting a seventh hit. The beam can travel up to 50 feet (2500 blocks) and can be fired faster than the blade can auto-swing, and deals more damage than the blade itself. Effects from a Flask will transfer to the sword ball as well.

The Terra Blade's best Modifier is Legendary. Improvements to the weapon's melee speed will also increase the velocity of the beam.
