The Light's Bane is a broadsword crafted solely out of Demonite Bars, considered to be an upgrade from the Gold Broadsword and the Platinum Broadsword. It has a Crimtane counterpart, the Blood Butcherer, which is stronger and larger but also much slower. It is one of the first five Demonite items available to the player, along with the Demon Bow, the War Axe of the Night, the Fisher of Souls, and the Malaise, as it does not require Shadow Scales to craft. It is notably faster and slightly smaller than the metal broadswords.
Its best Modifier is Legendary.
- The War Axe of the Night is often considered to be a better weapon than the Light's Bane, due to its increased damage and constant swing. In addition to this, it doubles as an axe. The Breaker is even stronger, but is incredibly slow, making it less efficient. Despite this, it is still important to craft the Light's Bane, as it is needed to craft the Night's Edge later on in the game.
- Many people consider this a useless weapon, as it is easily beaten by a phaseblade. However, as mentioned above, one is needed to craft Night's Edge.
