History of Eternity's Edge

Overview

Eternity's Edge is the Warlock class sword, a Legendary Solar Sword. Its flavor is Tarsem Sauer's line, "A sword is a wand that casts two spells: parry and cut." Destinypedia says it was originally an Adaptive Frame sword with Whirlwind Blade, Infinite Guard and Honed Edge, then reissued in Season of the Splicer on the Vortex Frame with perks like Tireless Blade, Thresh, Surrounded and Relentless Strikes, making it the first sword to have its frame changed.

It joins Quickfang and Crown-Splitter as the trio of class swords. It was Warlock-only until Episode: Heresy lifted class restrictions on weapons.

Acquisition

The source line reads "Complete the campaign as a Warlock". The reissued version drops randomly: GosuNoob names Banshee-44 as the best source, with Umbral Engrams, Legendary Engrams and rank rewards from Lord Shaxx and Commander Zavala also reported.
