Partner EXP comes from selling gear

Your Partner (and your Tamer) level up by selling the Equipment and Plugins you roll at the Hologram Device, not from clearing stages. Higher-rarity items sold give more EXP.

Fastest method

  • Spend Hologram Tickets at the Hologram Device and use the Auto function to spin and auto-sell continuously.
  • Level the Hologram Device with Bits. Higher levels roll better gear, which sells for more EXP.
  • Stock up on Hologram Tickets (idle rewards, DemiDevimon dungeon). See how to get them.

Digivolution then happens automatically at each level threshold. See How to Digivolve.
