I'm an old player (started playing in 2011) coming back after not playing for 10+ years and I wanted to ask you guys about the best ways to farm for sprite food. I have a Seraphynx but I've been struggling to level it up because of how much luminite I need to create Divine Orbs. Does anyone have any advice for what's the best place to grind for minerals? I don't mind putting the time in for that. I'm a Vanguard so I have access to all the missions too. Thanks!
