The quickest way to farm King Mong is to start from the exit to Arid Nexus, and see if he spawned near the turret. There is no catch a ride nearby, so you'd have to go through two more loading screens to get a vehicle and go check if he spawned in the other spot...instead, I just save and quit and keep checking the spot close by.
However, on top of the chances of getting the drop, and the chances of him spawning, there's a chance the Badaboom won't even be the right level.
So...OMG THIS IS SUCH A WASTE OF TIME.
Dammit, how did they think this would work out well? I've accomplished so little in weeks, trying to get good items.
so you'd have to go through two more loading screens
There's something wrong if you're getting loading screens within a level.
Last time I farmed King Mong he spawned near the gate closest to the Dust entrance more often than the other location. .
He's getting loading screens because he's starting at the Arid Nexus exit, going through to get a car and then traveling back to EB, I'd guess.
This is the wrong way to farm KM. Just fast travel to EB, grab a car at the catch a ride that's right there and proceed to farming. Takes like 3 mins or less per attempt including the save/quit/reload.
