Deterministic Chaos

Heavy Metal turns every fourth bullet into a heavy projectile that makes targets volatile on impact, as long as you keep the trigger held.

Vexadecimal builds on that: while holding the trigger, every fourth Heavy Metal projectile also weakens targets, and releasing the trigger after a Vexadecimal projectile partially reloads the magazine from reserves. The weapon is also strong against Barrier Champions.

The game data names the "What Remains" Exotic quest as the source, and What Remains is among the exotic missions available now. The weapon sits in the Neomuni Souvenirs badge, so it belongs to the Lightfall content.

Its catalyst adds Target Lock, which raises damage the longer the weapon stays on one target. The part list is Polygonal Rifling, Ricochet Rounds and a Composite Stock.
