Spinmetal - I usually run the rocket yard and collect chests and spin metal on the ground. Helium - also collect chests and helium on the ground, the area with the two servitors just going in circles either the caves orv the building spawn chests pretty frequently. Spirit bloom - the entrance to the nexus strike where you can farm the vex and fallen fighting each other the spirit bloom spawns really frequently Relic iron - this was the hardest for me until I found in the sunken city going into the building there's chest spawns also on the roof above building 3, I ended up getting quite a few rare chests that gave me 8-10 relic iron per chests Happy hunting
