History of Thriving Survivor

Overview

Thriving Survivor is a Legendary armor set for Hunter, Titan and Warlock introduced in Renegades. Destinypedia lists its source as the Lawless Frontier, and its bonuses reward Heat and Primary ammo final blows. One guide describes it as strongest in PvE against dense enemy groups.

Set bonuses

• Opening Act (2-piece): grenade final blows give Heat weapons bonus stability and vent speed, and Primary ammo weapons bonus stability and reload speed.
• Room Clearing (4-piece): multiple final blows with Heat or Primary ammo weapons grant bonuses to weapon and grenade stats and increase ammo generation for both weapon types.

Acquisition

Source: Lawless Frontier (Destinypedia). The page does not say whether this is a drop, vendor or other method. Check the in-game source before farming.
