hey guys where can I farm this from?
Converse with fellow players
Farm? If you mean the Ranger skill then it's not longer an item that is consumed. It became an active skill that you put in your sub palette in like EP 4?? 5??? So now you use it and it cools down for like 8 seconds and you can use it again. This goes for all grenade skills
If you mean the Braver PA, then.. I'm actually not sure. Let me take a look and I'll reply again!
Sorry, I have no answer. But it's a fairly common drop. Just make sure you're running as many things as you can and looking at all of your PA drops.
