Cells

Cells are items placed in the slots of weapons, armour, and lanterns to provide additional perks. Cells can provide a +1 perk, +2 perk, or +3 perk based on their rarity. Cells are usually acquired by opening cores, but they can also be obtained as rewards from mastery milestones, rare drops from behemoths, and The Lucky Break. The Middleman can fuse cells into higher power cells or even new cells.

The Middleman used to sell Cells in exchange for Aetherdust or Platinum.
