Terra Blade

The Terra Blade is a Hardmode projectile sword that can be auto-swung, and is the highest base-damaging sword in the. When used, it fires a green bolt projectile which costs neither mana nor ammunition, deals the same damage as the sword, and can pierce through two enemies, dissipating upon impacting a third or hitting a wall. The projectile can travel up to 5000 feet (2500 blocks) at a speed of 61 mph.

The Terra Blade becomes available after defeating one / all  Mechanical Bosses.

Tips

 * Some may argue whether the Terra Blade or The Horseman's Blade is more powerful. Damage-wise, the Terra Blade is better for both melee and ranged attacks.
 * With enough damage from the correct accessories, it is possible to do more than 400 critical hit damage.
 * In order to speed up the process of obtaining a Terra Blade, a Solar Eclipse can be spawned manually using a Solar Tablet. It is crafted from Solar Tablet Fragments which are dropped by enemies in the Jungle Temple. Although this biome requires defeating Plantera to enter, its enemies can frequently be found near the entrance door, and there are several methods to enter the Jungle Temple pre-Plantera.
 * Due to the fast speed and high damage of the beams, it is very effective to use the Terra Blade more as a projectile weapon then an actual sword. Even without the sword itself, it can still do massive amounts of damage at long ranges without the use of bullets or mana.
 * The Terra Blade on Mobile is considered to have some of the highest damage in the game, only losing to the Paladin's Hammer.

Trivia

 * Its crafting tree contains a total of eight different usable swords.
 * Its projectile is technically the only sword shaped melee projectile that can pierce through enemies and damage multiple enemies. The Influx Waver's projectile can also hit multiple enemies, but instead of piercing through enemies, its projectile will teleport and go after the closest enemy after it damages another enemy.
 * The projectile fired by the Terra Blade is referred to as the "Terra Beam" in death messages.
 * The Terra Beam’s color changes to yellow in a blood moon.
 * The Terra Blade itself bears a certain resemblance to the Night's Edge in terms of shape, while the projectile appears more similar to the Excalibur, as "forged from the finest blades of light and dark".
 * The sword's projectile, Terra Beam, resembles the True Excalibur's projectile with the color of the True Night's Edge's projectile.
 * Prior to 1.3, it was considered the strongest sword in the game, tied with The Horseman's Blade.
 * Crafting the Terra Blade requires the most raw ingredients of any sword:
 * 30 / 40  Demonite / Crimtane Ore
 * 12 Jungle Spores
 * 12 / 15  Stingers
 * 1 Muramasa
 * 60 Hellstone
 * 20 Obsidian
 * 12 Hallowed Bars
 * 2 / 3  Broken Hero Swords
