On planet Venus head to Ember Caves area, where you will find another cave with quick rewpawning creatures level 11.
This spot is not far away from the starting location in a free roam patrol Venus. Just like the farming spot in the cave on the planet Earth the creatures will start spawning when you move away from the cave entrance, thus, go to the left side behind a blue tank. For Vandal mobs use your Rocket Launcher, while Fusion Rifle save for the Captain and his shield. If you consume Spirit Bloom item, it will increase the Glimmer drop. You can also complete Queen’s Wrath bounty – Extermination Protocol where you have to defeat 200 Fallen with headshots.
