Elucidator

Elucidator is a weapon used by Kirito in the light novel/anime/manga series Sword Art Online. It, alongside with Dark Repulser, were his primary weapons while trapped in the video game Sword Art Online.

Appearance
Elucidator is a black longsword with silver trim. It has a black, cylindrical hilt and a spiked hand guard that attaches to the lower part of the blade. A small, silver design is emblazoned just below the blade's tip.

Powers and Abilities
Elucidator's primary attribute is its extreme durability. It is also extremely strong, and is able to deal great damage to in-game enemies. Equipping it also boosts Kirito's physical strength and agility.

History
Kirito obtained Elucidator as a rare weapon drop after defeating a boss on the 50th Floor. At first, he lacked the strength statistics to wield it, and had to level up before equipping it as his primary weapon. When visiting his blacksmith friend Lisbeth, he asked her to forge another sword equal to Elucidator in strength and durability, and even tested her weapons by hitting them with the sword. He laster had her boost its stats for greater strength.

Kirito continued to use Elucidator and Dark Repulser in Sword art Online, using them both to defeat The Gleam Eyes, the Skull Reaper, and finally the game's creator Kayaba Akihiko. Kirito was disarmed, but managed to defeat Kayaba and escape the game.

Later, when Kirito joined the game ALfheim Online to save his girlfriend Asuna Yuuki, he found that the two games had identical save formats, and he could load items and weapons from Sword Art Online. However, due to data corruption, Kirito had to delete them, including Elucidator.
