Update: It looks like that exploit is being fixed tomorrow. From the v 1.02 patch notes that just came out ahead of time: “Named NPCs will no longer respawn after being killed in the Open World. This will prevent situations where players were able to kill a same named NPC over and over again.” So smoke ‘em if you’ve got ‘em.
High-level players of The Division have discovered a way to make hundreds of Phoenix credits (currency used to buy high-end weapons) and collect dozens of special items in less than an hour by attacking the same NPC over and over again in quick succession. It is the closest thing to Destiny’s erstwhile “loot cave” – a fruitful, if repetitive, means to get lots of goodies late in the game. And sadly, it is only useful to those who have reached level 30.
