Best In-App Purchases
If you spend, these give the best value. The game is fully clearable free-to-play — nothing here is required. Verdicts from GameWith.
DigiDiamond Pass · $5.99 / month
200 DigiDiamonds instant + 3,000 over 30 days (3,200 total). ~68.75% off — but needs daily login.
Ad Skip Pass · $8.99 · one-time
Permanently removes ~30 ad prompts/day. Prioritise if you value time; no direct power gain.
Hologram Pack · $1.99 / day
800 DigiEmeralds + 500 Hologram Tickets.
Dungeon Pack A & B · 160–320 diamonds/day
Digital Gates for extra dungeon runs; value rises with dungeon difficulty.
Summon Ticket Pack · 540 diamonds/day
30 Skill Card + 30 Support tickets (~55% off).
Battle Pass (Digital Boost) · $5.99
MarineBullmon, 4,500 DigiEmeralds, 4 Skill Card + 4 Support tickets, 180 Acceleration Tickets, 600 Buddy Soul, 300 DigiPlates. Recommended for the Buddy/SP tickets — but rewards unlock via mission points (~1 level/day).
Top priority
The DigiDiamond Pass ($5.99/mo) is the best raw value; the Ad Skip Pass is the best quality-of-life buy. Both need consistent play to pay off.
Should You Buy Limited-Time Sales?
Verdict: yes — especially early game
Time Sales hand out a large number of tickets that speed up early progression. They last only 24 hours and pop up as you hit milestones (leveling the Hologram Device, Skill Card / Support Summon levels, Partner progress, content unlocks), so decide quickly.
