Stalker's Armor is gotten from quests in Tier 3 zones. Each piece is from a quest in a different zone. The quests for the set pieces are in two stages. First quest involves killing players in RvR, the followup quest will have you kill a hero unit in the same zone as the quest. Collecting all four pieces gives a tome unlock and grants the title The Stalker.
