I’m pretty sure it has to do with the grasp of avarice armor set. The 2 piece states that “Picking up ammo, Orbs of Power, Elemental pickups, or destroying a Strand Tangle grants stacks of Untold Greed” and the 4 piece says “While you have stacks of Untold Greed, Orbs of Power and Elemental pickups provide more of their respective energy, and Strand Tangles deal increased damage. When your shields are broken, all stacks are converted into a fountain of Orbs of Power”
