Building powerful Digimon in Digimon Story Time Stranger isn't just about leveling up or evolving fast. It's about understanding how bonds, personality types, and stat stacking work together to create truly strong digital monsters. This guide explains how to make your Digimon stronger step-by-step—from increasing bond levels to aligning personality types and optimizing your digital loop for maximum stat growth.
| Mechanic | Importance | Max Potential | Time Required |
|---|---|---|---|
| Bond Level | Foundation of power | 100% | Medium |
| Personality Types | Stat growth direction | 16 types | Variable |
| Digital Loop | Stat stacking | 100 iterations | Long-term |
| Load Enhancements | Rapid stat gains | 100 uses | Short-term |
| Agent Skills | Additional bonuses | Multiple nodes | Progressive |
Before you start worrying about stats, weapons, or evolutions, you need to raise your Digimon's bond level. A strong bond allows your Digimon to retain and stack stats every time you Digivolve or De-Digivolve—a process often referred to as the digital loop.

At 10% bond, you'll start seeing stat retention after Digivolving. The higher your bond, the greater your Digimon's long-term growth potential. With maximum bond, your Digimon can inherit stats up to 100 times through the digital loop process.
The easiest way to increase a Digimon's Bond is to have them participate in battles. Only Digimon assigned as Battle Members will have their Bonds increased—those listed as Reserve Members and in the box cannot increase their Bond levels.
It takes around three to four battles before the dialogue option appears again, but this method costs no money and builds naturally through gameplay.
After unlocking the DigiFarm, you can provide your Digimon with food to increase their Bond rapidly. You can purchase food for your Digimon at the food shop in Shinjuku.
While this speeds things up, it can become expensive if you're pushing toward 100%. If you want to make money faster, consider the Money Dungeon or use the Millionaire USB from the Public Safety Suit bundle—it doubles your income and makes bond training more affordable.
Strong Digimon don't rely only on stats—their personality type determines how effective their abilities and skills are. Each Digimon's personality impacts their growth focus (Attack, Defense, Support, etc.).
There are four basic personality traits in Digimon Story Time Stranger: Valor, Philanthropy, Amicability, and Wisdom. Each quadrant gets further broken down into four subtypes, creating 16 total personality combinations.
| Personality | Intended Role | Base Stat Boost |
|---|---|---|
| Valor | Physical Attacker | +ATK |
| Philanthropy | Healer | +SPI |
| Wisdom | Magic Attacker | +INT |
| Amicability | Support | +DEF |
Each personality subtype provides specific stat bonuses, creating a two-layer system of stat control:
| Philanthropy (+SPI) | Valor (+ATK) | Wisdom (+INT) | Amicability (+DEF) |
|---|---|---|---|
| Adoring: +DEF | Zealous: +SPD | Enlightened: +SP | Opportunistic: +SPI |
| Devoted: +INT | Brave: +SPD | Sly: +HP | Friendly: +ATK |
| Tolerant: +SP | Reckless: +HP | Astute: +SPD | Sociable: +SP |
| Overprotective: +HP | Daring: +DEF | Strategic: +SPI | Compassionate: +HP |
When you're exploring in any area with your active Digimon also visible on the map (dungeons of all kinds, mainly), you will be able to talk to your Digimon roughly every five minutes or so. Sometimes, when you're in areas that don't allow your Digimon out and about, you'll get messages from them on your Digivice.
As you answer your Digimon's questions, the angle of the Personality change will be tilted diagonally toward another subtype. The symbol(s) shown beside your possible answers are representative of the four quadrants:
When an answer lacks a symbol, which is usually the second of two possible responses when your Digimon is talking to you face-to-face, that answer shuts down the possible Personality shift, keeping things as they are.
There are 32 possible Personality Skills, and each of your Digimon can only have one at a time. The chance to learn a new one presents itself when their Personality subtype shifts. Each time that happens, you're presented with an opportunity to swap it out.
For instance, Steadfast Emotion is one of the possible Personality Skills linked to the Astute subtype. A Digimon who has the Steadfast Emotion Personality Skill equipped will have their INT boosted when HP is 90 percent or lower. The lower their HP drops, the higher the boost.
The Digital Loop—Digivolving and De-Digivolving repeatedly—is the key to long-term stat growth. Each time you loop, your Digimon retains a portion of their previous stats. Over time, this cumulative stacking makes them significantly stronger.
A Digimon with a high Bond percentage will be able to inherit its cumulative stats when Digivolving and De-Digivolving. This allows them to boost their stats, up to 100 times max. With this in mind, a De-Digivolved Digimon with a high bond will be able to retain its stats, and Digivolving it allows you to have it start from Level 1 and gain more stat increases further.
While raising your monsters, you'll notice you will lack stats to further Digivolve into certain branches. To remedy this, you need to De-Digivolve and head to other branches for more Cumulative Stats. This strategy is essential for accessing higher-tier evolution lines that require specific stat thresholds.
When you reach high bond and talent levels, you can begin loading other Digimon into your main one. This process transfers a portion of experience and stat power, helping you level faster without grinding battles endlessly.
Blue Stat Gained = [(Current Stat - Base Stat) x 5%] + (Loaded Digimon Blue Stat x 50%)
You can also gain Cumulative Stats from Load Enhancements by loading in Digimon who already have Levels and Cumulative Stats. By feeding Digimon with increased Stats, you can increase the Cumulative stats of the Digimon you fed it to based on what the sacrificed Digimon had.
Ask yourself these three questions before committing:
You want to be able to say yes to the first two, and no to the latter. Avoid this with especially rare Digimon—their stat boosts are likely to be terrific, but unless you're well and truly fine with seeing them sent off for a while, it's a dicey proposition at best.
You can increase your stats with Augment Chips, Levelling-up, or via Load Enhancements. The more you can get your stats up, the more Digivolution branches you can unlock for certain Digimon on top of stats.
The DigiFarm is essential for maxing out your Digimon's Stats and Bond. Bond determines how much of your stats carry over when Digivolving and the Stats you gained by training at the Farm won't mean much if they don't carry over after Digivolution.
A digimon's level is capped by its Talent Stat. You can increase this by participating in battles, Digivolving, Load Enhancements, and Training at the DigiFarm. As your Talent total rises throughout Digimon Story Time Stranger, level caps rise, and overall benefits seem to improve as well.
| Level | Move Level Cut Off |
|---|---|
| Rookie | 10 |
| Champion | 25 |
| Ultimate, Armor, Human Spirit, and Beast Spirit | 40 |
| Mega, Mega+, Hybrid Spirit, Transcendent Spirit, and Gold Armor | 45 |
Listed above are the Level cutoffs for when each Digimon Stage stops learning new Attachment Skills. You can obtain different Attachment Skills from every Digimon at certain levels.
By branching out to other Digivolutions, this will also give you a wider variety in Support Skills and Elemental Coverage. Attachment Skills can be equipped and unequipped by any Digimon at any time. If your Physical Attacking Digimon learns a Magic Skill, feel free to not learn it and put in on your Magic Attacking Digimon instead.
Outside of bonus EXP and Cross Arts, Agent Skills also buff certain Digimon depending on their Personality. Make sure to unlock these nodes as you complete Missions for a free boost in your Digimon's stats.
Once your Digimon reaches max bond and talent, you're ready to focus on the final polish:
At this point, your Digimon will be able to handle high-level battles, bosses, and late-game challenges with ease.
Most Digimon now rely on their Signature Attacks. Some Digimon, namely Mega Levels, now have updated Signature Attacks that have additional effects like decreasing DEF, SPI, and Elemental Resistance. Do try to slot in Support Digimon like these since they're preferred over Digimon that just do damage.
Build balanced teams with type diversity:
The best strategy to level up is to kill all enemies in a small area with a high concentration of wild Digimon, leave the map, and come back to respawn them. This method is efficient for both experience and bond building.
If you want to make money faster for DigiFarm training, consider the Money Dungeon or use the Millionaire USB from the Public Safety Suit bundle—it doubles your income and makes bond training more affordable.
You need at least 10% bond to start retaining stats when Digivolving or De-Digivolving. However, 100% bond is ideal for maximum stat retention.
You can perform the digital loop (Digivolving and De-Digivolving) up to 100 times per Digimon for maximum stat stacking.
Valor personality types are best for physical attackers, with subtypes like Zealous and Brave providing additional SPD bonuses for faster attacks.
Yes! You can influence personality by answering your Digimon's questions during exploration. Each answer has symbols representing the four personality quadrants.
Generally no—only use Load Enhancement with common, easily replaceable Digimon. Rare Digimon provide good stat boosts but are hard to replace.
The fastest method is using the DigiFarm with food that your Digimon loves (shows a heart icon), providing +2% bond per feeding instead of +1%.
No, only Digimon assigned as Battle Members can increase their bond levels. Reserve and boxed Digimon won't gain bond.
With sufficient bond level, your Digimon will retain a percentage of its stats (10% of previous stat value) when De-Digivolving, allowing for cumulative stat growth.
Personality skills are learned when your Digimon's personality subtype shifts. You'll be presented with an opportunity to learn or swap skills during these changes.
Most stats can be raised to 9999 through a combination of leveling, training, Load Enhancements, and the digital loop process.
Making strong Digimon in Digimon Story Time Stranger comes down to three things—bond, personality, and stat stacking. By combining these steps, your Digimon won't just evolve—they'll dominate.
