How to Change Digimon Personality and Solve Its Traits in Cyber Sleuth

Select Language:

Taking care of your Digimon has never been more enjoyable than in the Digimon Story: Cyber Sleuth games. These digital monsters range from cute to incredibly cool, and it’s easy to become attached to them after battling with them for so long.

One interesting aspect is that, similar to Pokémon, each Digimon has its own personality. While these personalities don’t influence stats when leveling up like in Pokémon, they still have mechanical effects in the game — and you can change them at will!

Updated November 4, 2025: We’ve updated this article with some advice on the best personality types to choose for your team!

Digimon Personality Overview

In Digimon Story: Cyber Sleuth, there are eight unique personality types that every Digimon will have. These personalities are important for managing DigiFarms.

DigiFarms are digital storage spaces where you can interact with your Digimon by feeding them, setting training routines, or assigning tasks. Each DigiFarm has a leader Digimon. The personalities of both the DigiFarm’s leader and each Digimon impact the results of these activities.

Here’s how personalities affect DigiFarm commands:

Personality	Effect	Leader Effect on ‘Train’	Effect on ‘Develop’	Effect on ‘Investigate’
Durable	Bonus to HP gains	Boosts everyone’s HP gains	—	—
Lively	Bonus to SP gains	Boosts everyone’s SP gains	—	—
Fighter	Bonus to Attack (ATK)	Boosts everyone’s ATK	—	—
Defender	Bonus to Defense (DEF)	Boosts everyone’s DEF	—	—
Brainy	Bonus to Intelligence (INT)	Boosts everyone’s INT	—	—
Nimble	Bonus to Speed (SPD)	Boosts everyone’s SPD	—	—
Builder	Speeds up development tasks	—	Reduces development time	—
Searcher	Speeds up investigation tasks	—	—	Shortens search time

Knowing this, you can organize DigiFarm rosters to meet your goals. For example, having a full team of Builder Digimon for development tasks or Searcher Digimon for investigating tasks can cut their completion times to just 20 minutes each.

Note: A Digimon can gain a total of half its ABI (Ability) plus 50 stat points through training. For example, a Digimon with 16 ABI could gain up to 58 stat points. Use this info along with Restraint Chips, which reduce trained stat gains, to build your Digimon just the way you want.

How to Change a Digimon’s Personality

You can modify a Digimon’s personality using special patches. These patches are most easily obtained by purchasing them at the Eden Entrance in Chapter Two, costing 2,500¥ each. They can also drop from enemies but are more affordable when bought.

As you progress, more types of patches become available:

Chapter Two:
- Development Patch (changes personality to Builder)
- Searcher Patch (changes to Searcher)
Chapter Seven:
- Durability Patch (Durable)
- Lively Patch (Lively)
- Fighter Patch (Fighter)
Chapter Twelve:
- Defender Patch (Defender)
- Brainy Patch (Brainy)
- Nimble Patch (Nimble)

Best Personalities for Your Digimon

While personalities impact how your Digimon will gain stats from DigiFarm training, their main strategic role is to decide where the +100 bonus stat points are allocated at the end of training. A fully maxed Digimon can assign these points to only one stat: Attack, Defense, HP, Speed, or Intelligence.

To optimize this, apply the appropriate personality patch (e.g., Fighter for Attack, Brainy for Intelligence, Nimble for Speed) before starting the final training phase. This ensures all +100 bonus points are dedicated to the stat that makes your Digimon most effective in its role.

Here are the most common roles and ideal personalities:

Role	Optimal Personality	Why?
Physical Attacker	Fighter	Maximizes physical damage output
Special Attacker	Brainy	Maximizes magical damage output
Support	Speed	Ensures support moves are used earlier, vital for healers
Physical Wall	Defender	Boosts damage reduction, good for high-HP Digimon
Hybrid Wall	Durable	Maximizes HP for soaking up attacks, ideal for skills scaled on max HP
