Hey everyone there's another loot cave I've found on Venus. You have to start the mission right underneath the nexus and go to the point where the fallen are fighting the vex and kill them for a bit and one of the black caves near the spiral staircase room will have infinite fallen dregs spawn. Beware though stronger enemies of fallen will spawn too. I'm not too sure if this is a one time thing I experienced but letting everyone know this exist currently.
