Lambent Light

«Lambent Light» (ランベントライト) is a one-handed rapier owned by Asuna. Asuna's degree of proficiency with her sword is 1000 (mastered). Her rapier, combined with her speed, earned her the nickname «The Flash». Lisbeth boosted her weapon to +40. It is her end weapon used until the clearing of SAO.

It is first named in the side story Warmth of the Heart, as a work done by Lisbeth, who stated it was of a quality she could only forge once a month.

This is Asuna's last rapier in Sword Art Online which she continues to use it as her main weapon of choice until the fateful battle on the 75th Floor. Kirito uses this rapier to stab and defeat Heathcliff in the final battle, clearing the game.
