What Is SPI in Digimon Time Stranger? INT, Bond & Stats Explained
Time Stranger's stat screen throws abbreviations at you with zero explanation — and building a team around the wrong stat wastes dozens of hours.
The three that confuse everyone: SPI, INT, and Bond. Here's exactly what each does, which Digimon need them, and the fastest route to 100% Bond.

SPI (Spirit) is the game's support stat: SPI enhances healing effectiveness, making it the ideal stat for support Digimon.
What that means in practice:
- Higher SPI = bigger heals from recovery skills.
- It's the priority stat for dedicated healers and cleric-type Digimon in your back row.
- If a Digimon's job is keeping your Megas alive through endgame bosses, SPI is its main number.
If you're wondering what SPI is in Digimon games generally — it's a Time Stranger-era stat; older games like Cyber Sleuth handled support scaling differently (more in our Cyber Sleuth ABI & CAM guide).
What Does INT Do in Time Stranger?
INT (Intelligence) is your magic attack stat: INT enhances magic-based attacks and abilities, ideal for ability-based Digimon.

The simple split to remember:
- ATK scales physical attacks — the stat for attack-type Digimon.
- INT scales magical/special attacks — casters like Wizardmon-lines and angel types.
- Check each skill's type before investing: pumping ATK on an INT-based Digimon (or vice versa) is the most common wasted-build mistake in the game.
Which stats grow automatically depends on personality — the 16 personalities define which stats get priority on level-up, so pair this guide with our personality guide to point growth at the right number.
What Does Bond Do in Time Stranger?
Bond looks like a friendship meter, but it's secretly one of the most important progression stats in the game. What Bond actually does:
- Stat inheritance: Bond dictates how many times a Digimon carries over cumulative stats when Digivolving or De-Digivolving — each evolution carries over 1% of stats, and each Bond percentage point equals one stat-carrying evolution. 20% Bond = 20 stat-inheriting evolutions. This is the engine behind endgame stat-stacking builds.
- Combat buffs: Higher Bond increases the chance of extra follow-up attacks and Critical Hits — confirmed and enhanced in a patch, which also added higher item drop chance (counted from your single highest-Bond Digimon only).
- Talent synergy: Digivolving with at least 10% Bond grants bonus Talent growth — connecting directly to our max level guide. PCGamesN
- No downside: Bond is never lost through any evolution — hop up and down the Digivolution tree freely.
How to Increase Bond in Time Stranger (Fastest First)
Every method, ranked by speed:
- 1. Favorite food at the Digifarm (fastest): Feeding a Digimon its favorite food raises Bond 2-3% per item — about 50 favorite foods hits 100% Bond, costing roughly 10k (one level 2 outer dungeon run's earnings). Watch the eating reaction to gauge the gain, and match food to each Digimon's likes.
- 2. Digimeat dungeon loops: Each "Protect the Digimeat" outer dungeon clear adds 1-3% Bond — and it's the same loop that maxes Talent, so you're double-dipping.
- 3. Field conversations: Speech-bubble interactions (appearing every 3-4 battles) add 1% Bond each — and steer personality at the same time.
- 4. Regular battles (passive): Battle Members gain Bond from fights, Reserve Members gain it slower, and boxed Digimon gain none — so keep priority Digimon out of the box.
- 5. Friendship S items: Each gives +1% Bond to any Digimon and drops from the Digimeat farm.
Strategy note: focus Bond on a small number of priority partners you'll use for several chapters rather than spreading effort across the roster — Bond on benched Digimon you'll never evolve is wasted effort. Full mechanics tables live on Game8's Bond guide. Position Is Everything
Quick Reference: Every Stat in 10 Seconds
- ATK — physical damage
- INT — magic/special damage
- SPI — healing power (supports)
- DEF/SP.DEF — physical/special damage taken
- SPD — turn order
- Bond — stat inheritance count + crits/extra attacks + drops
- Talent — level cap (full guide)
- Personality — which stats grow on level-up (full guide)
Conclusion
The short version: SPI powers healing, INT powers magic attacks, and Bond controls stat inheritance across evolutions — plus crits, follow-ups, and drops. Feed favorite food at the Digifarm for the fastest Bond gains, keep your priority team out of the box, and match each Digimon's build to the stat its skills actually use.
