A Phasesaber is an upgraded version of the Phaseblade, craftable using Hardmode materials. It looks identical, but deals nearly twice as much damage as the Phaseblade, and swings automatically while you hold down the left mouse button, similar to the Muramasa and Cobalt Sword. It is crafted from 50 Crystal Shards and a Phaseblade, with its resulting color determined by the color of the Phaseblade used to craft it; For example, a White Phaseblade and 50 Crystal Shards makes a White Phasesaber.
As with Phaseblades, all Phasesaber colors have the same statistics and emit a small amount of light when swung. Like other Broadswords, Phasesabers are swung over the head.
The Phasesaber is fantastic for Hardmode as it can be acquired early and, when reforged properly, its overall damage per second is unbeatable until obtaining the Excalibur.
- The different colors can be used to separate teams in player vs player games.
- Like Muramasa and Cobalt Sword it is great for fighting, due to its high attack speed and automatically repeating attacks when holding the attack button.
- In addition to the weapon's visual appearance, Phasesabers and Phaseblades emit a sound effect reminiscent of a Lightsaber from the Star Wars franchise.
- The requirement of crystal shards in the production of the Phasesaber may be a reference to the fact that all Lightsabers require a Saber Crystal in order to function.
