History of Duty Bound

Overview

Duty Bound is a Legendary Kinetic Auto Rifle with an Adaptive Frame. The D2 Wiki's curated Season 16 roll pairs Polygonal Rifling and Ricochet Rounds with Compulsive Reloader and Rampage, plus the Stunning Recovery origin trait (refills the magazine and restores health when you stun a Champion). Handling is 63 and aim assistance 73. The flavor quotes a Guardian speaking to Commander Zavala.

Acquisition

The D2 Wiki lists the Season 16 version as a Nightfall drop, with an earlier Season 2 version also existing, so it has been reissued. Its source tag in-game points to Commander Zavala's vanguard rank-up rewards.
