History of Last Thursday

Last Thursday is a Legendary Strand Pulse Rifle (energy slot) from The Edge of Fate, a 390 RPM Adaptive Frame. A strong PvE roll is Demolitionist with Frenzy, and a strong PvP roll is Moving Target with Elemental Honing. Its high horizontal recoil makes Arrowhead Brake close to essential.

Acquisition

Dropped by enemies and chests on Kepler (the "Exploring Kepler" source), or targeted through Focused Decoding at the Altar of Relativity using Fated Ciphers and Phaseglass Refractions. Like all Kepler weapons it carries the "Exhaustive Research" origin trait, which loads micro-missiles when aiming at enemies.
