History of Shrewd Survivor

Overview

Shrewd Survivor is a Legendary armor set for Hunter, Titan and Warlock introduced in Renegades. Destinypedia lists its source as the Lawless Frontier activities, without saying whether this is a raid, dungeon, activity or vendor. Its bonuses reward switching to and fighting with Heat weapons, Submachine Guns and Hand Cannons.

Set bonuses

• Reflex Action (2-piece): swapping to a Heat weapon, Submachine Gun or Hand Cannon grants a short boost to handling and accuracy, extended by dealing damage with that weapon.
• Hotshot (4-piece): final blows while Reflex Action is active give a weapon stat bonus and extra stability, reload and aim assist on those same weapon types for a moderate duration.

Acquisition

Source: Lawless Frontier (Destinypedia). No drop rates, season tie-ins or vendor details are listed. Search snippets did not confirm the exact drop method.
