That aug seems super rare. At least that’s what I hear. Some how I got lucky as F and it dropped on the 5th kill. Wasn’t even looking for it. Found an open camp and took it. Maybe I should buy a lotto ticket.
RNG is random. I haven’t had good luck at this camp either. Named once every 3 hours, and a 1/4 ish drop rate on the aug. With random numbers, all you can do is throw time at it. Redguides here has a panoply tools to help with the task.
Think you guys might be confusing what increased spawn rate means for some mobs. Let's say a mob has a 10 percent chance to spawn. You're increasing that spawn chance by 50% (so instead of 10 percent it's like 15 percent). I think that's the way it works. 50% increase does not mean that a named has a 50% chance of spawning which is what a majority of people keep misunderstanding about "increased rare spawn" events.
