Cyber Sleuth never properly explains its two most important hidden stats — then locks your favorite Megas behind them. If your Digivolution screen keeps showing red ABI or CAM requirements, this guide fixes that.
Everything below applies to both Cyber Sleuth and Hacker's Memory (and the Complete Edition), since they share the same systems.
What Is ABI in Digimon Cyber Sleuth?

ABI (Ability) is a hidden growth stat that does two things:
- Gates Digivolutions: as you reach Ultimate and Mega Digimon, you'll hit ABI requirements ranging from as low as 20 up to 100.
- Raises your bonus-stat cap: every 2 points of ABI lets you add 1 more training point, and max ABI is 200 — equating to 150 total bonus points. Higher ABI means more farm training, which makes hitting Digivolution stat requirements far easier.
Crucially: leveling does NOT increase ABI — only Digivolving and De-Digivolving do.
How to Increase ABI (The Loop)
The core method is the Digivolve ↔ De-Digivolve loop:
- Bounce back and forth between evolutions — you gain ABI in both directions.
- De-Digivolving pays more: Digivolving grants roughly 10 ABI while De-Digivolving can grant around 20 at higher levels — and the higher the stage (Mega, Ultra), the more ABI each De-Digivolve gives.
- Level before you drop: the community formula scales with level — roughly 2 + (level/5) ABI for de-digivolving a Rookie, 3 + (level/5) for a Champion, and so on — so main gains come from de-digivolving at higher levels.
- Don't over-grind levels though: several quick de-digivolutions beat fewer slow ones — de-digivolving at 99 gives only about double the ABI of level 50 but takes vastly longer.
The efficient routine: level fast to a comfortable ceiling → De-Digivolve → re-Digivolve → repeat. Always fulfill ABI requirements before stat training — Digimon reset to level 1 when evolving, wasting trained stats if ABI wasn't ready.

Item shortcut: Miracle Meat raises ABI directly but is expensive and limited — around ¥1,000,000 for +20 ABI. Use it for the last few points, never as the main method GameRantjhu.
What Is CAM in Digimon Cyber Sleuth?
CAM (Camaraderie) is the friendship stat, and it matters more than it looks:
- CAM increases the chance of combo (team-up) attacks in battle — which are very handy against bosses Nancy Nogo Blog.
- Like ABI, CAM is a requirement for certain Digivolutions — famous examples being fan-favorites in the Mega tier.

How to Raise CAM (All 3 Methods)
- 1. Battle with them: CAM rises about 1% per battle — the Digimon must actually be on the battlefield, not just benched.
- 2. Feed meat at the DigiFarm (fastest): cheap meat raises CAM 1-2 with a small fail chance; bigger meats raise it faster. Basic Digimeat caps at 20 on the farm and replenishes over time, each giving 1% CAM.
- 3. Answer the DigiLine: every answered DigiLine call gives +1% CAM — small, but completely free, so always answer.
Order of operations tip: boost CAM after fulfilling stat requirements if you're running Tough Training — some farm trainings trade CAM away.
The Complete Prep Checklist for Any Mega
Putting it together, here's the pre-Digivolution routine veterans use:
- Scan targets to 200% before converting (higher starting potential — a habit that carried into Time Stranger's Talent system).
- Run the level → De-Digivolve → re-Digivolve loop until ABI meets the requirement.
- Farm-train stats (group Digimon with shared stat needs, matching leader personality).
- Feed meat + answer DigiLine until CAM clears the bar.
- Digivolve — and enjoy your Royal Knight or demon lord of choice.
The full formula tables live in the community's GameFAQs ABI research thread if you want exact numbers per stage.
Wondering if the game's worth starting in 2026, or whether to play it before Time Stranger? Our Cyber Sleuth chapters and length guide answers both.
Conclusion
How to increase ABI in Digimon Cyber Sleuth: level up, De-Digivolve (it pays roughly double), re-Digivolve, and repeat — higher stages and higher levels give more per cycle. CAM is simpler: battle actively, feed farm meat, and answer every DigiLine call.
Master these two hidden stats and no Mega in the game stays locked for long.
