The White Phasesaber is a Broadsword that emits light when swung. It is an early hardmode weapon that can be acquired after the player defeats the Wall of Flesh and finds the Underground Hallow biome. It is a near identical version of the White Phaseblade except that it is slightly larger version that inflicts 20 additional damage and can attack continuously while the left mouse button is held down, similar to the Muramasa. This additional damage also grants it a higher overall DPS than even the Adamantite Sword (102.5 to 99.8), making it the best sword until obtaining Excalibur. Because of this and the fact that Crystal Shards are easily obtainable in the Underground Hallow, the Phasesaber is an excellent and worthwhile weapon to craft as soon as you can after entering Hardmode.
