Aniimo Build Systems Explained: Personality, Held Items, Contracts and Potential

Every Aniimo build is the same seven systems: stats, Potential, personality, held item, contract, talents and evolution. This is the reference for all of them, including all 18 held items and which contracts are worth your Marks of the Strong.

Update 1.1 · Oct 2026Game8 + GameWith + KairosAll 18 held items

The six stats (and why there's no crit)


Aniimo have six stats: HP, Attack, P.DEF, M.DEF, Break and Regen. There is no Crit Rate or Crit DMG stat to level. Every skill also shows its Might (scaling) and EP cost, and held items add Damage Amp.

Base crit
10% / 50%

Rate and damage. Extra crit only comes from the Nimble personality (+5%), Floral Rainbow Feather and a few kits.

Break units
Break > ATK

The formula uses the higher of the two, so Attack on a breaker is wasted. Crit does raise break damage. 19:30

Support damage
Level

Regen, heal and support damage scales with level, not Attack. Exceptions: Dazmand (Attack) and Somniwing (Regen).

RoleWhat to buildWhat it does for the team
DPSAttack, then Regen, then a little HP and defenseDeals the damage in the break window
BreakBreak, then Regen. No AttackEmpties the enemy's shield for the 2.5× window
RegenRegen onlyRefills party EP (only while on the field, except kits like Somniwing's)
HealHPHeals scale off max HP (Glacy)
SupportRead the kit (Turbo's shield = HP, Dazmand = Attack)Buffs and debuffs

Potential: innate, acquired, and how to read the stars


Each stat has Innate Potential (rolled at capture or hatch) and Acquired Potential (raised with Capability Awakening). Together they're capped at 20 per stat. Potential multiplies what each level gives, and the bonus applies retroactively.

Grades

Each Aniimo has two core stats. Their innate max sets the grade: Common ≤3, Good ≤5, Elite ≤7, Perfect 8+. A 10 is Crowned; 10/10 on both cores is the "Sunglasses" Perfect. Umbral Aniimo always roll Perfect. 1:00

Going past 20

Star-up ascensions give +1 to all six potentials, 6★ adds more, and some held items add +2 (the Tier 1 effects). Capafruit adds +1 innate to every stat, once per Aniimo. 10:43

Reading Game8's Potential stars

Game8 rates each stat from 1 to 5 stars per unit (GameWith calls it "Recommended potential"). Put Awakening into the 5s first, then the 4s. Treat 1 to 2 stars as "leave it."

Kairos goes further on DPS

He personally builds every stat on his main DPS, and maxes Regen and Break on Fulmintis too. That's an endgame luxury; while progressing, stick to the 5-star and 4-star stats. 12:49

Personality: what each letter does


A personality is four letters, one from each pair, and each letter grants a small combat bonus. In practice only the first two slots matter much for damage.

SlotOption AOption B
1E Energetic: ATK +2%, BREAK +2%I Instinctive: REGEN +4%
2S Practical: DMG +4%N Nimble: Crit Rate +5%
3T Tenacious: P.DEF +6%F Faithful: M.DEF +6%
4J Judicious: HP +4%P Playful: DMG Reduction +4%

Best personality per role: Game8 vs Kairos

RoleGame8 (general rule)KairosVerdict
DPSEN-- (ENFP, ENTP, ENFJ, ENTJ)Energetic + Practical (ES--). Nimble only for crit kits like FulmintisDisagree Kairos's math: Nimble's +5% crit is only ~2.38% more damage at base crit, less than Practical's 4%. Many Game8 unit pages pick ES anyway (Sherro, Infergon ESTP).
BreakES-- (ESTP, ESFP, ESTJ, ESFJ)Energetic + Nimble (EN--), because crit raises break damageDisagree Both want E. Game8's Blazen page itself picks ENTP.
HealI--J (ISTJ, ISFJ, INFJ, INTJ)Judicious first, then Instinctive (ISTJ on Glacy)Agree
Regen / SupportI--JInstinctive for Regen; supports depend on the kitAgree on I. Attack-scaling supports (Dazmand: Game8 ENTJ) want E.

Kairos: "the top two slots matter," so ignore slots 3 and 4 on DPS. 15:15 17:37

Unit exceptions

Game8 gives Irisalis ESTJ, Stellarys ISTP and Fulmintis ENTP. Always check the unit's own page over the role rule.

Locked

Helion is fixed at ENFP and Lunara at ISTJ. Don't spend Psyche Fruit on them. (GameWith lists Lunara as ESTJ, which can't happen.)

Psyche Fruit

Rerolls all four letters at random, with no locks and no confirmation prompt. Kairos needed 3 for his Stellarys. Use them last.

🎯
Homeland bonus

Personality also gives +20% at specific Homeland facilities, so a "wrong" combat roll can still make a good worker.

All 18 held items and their best users


Each Aniimo holds one item. Every item has a Main Stat and a Core Effect that works at any level or rarity. Higher-rarity items also unlock a Tier 1 effect at item Lv 10 and a Tier 2 (Advanced) effect at Lv 15.

Values are Game8's for the listed rarity; higher rarities have bigger main stats. Game8 writes the Tier 2 conditions as "ATK above 15" and "Acquired Potential exceeds 15"; both most likely mean Acquired Potential points. GameWith's item picks match Game8's on only 34 of 67 units and look templated by role, so Game8 is used above.

⚠️
Enhancing rule

Only level top-rarity items. Feeding an upgraded lower-rarity item into a better one loses 20%. To farm a specific item, filter the Institute Guide's Aniimo Challenge by Held Item to see which Alpha drops it. 11:27

Contracts and Marks of the Strong


A Legendary held item at Lv 15 can be contracted to a species with 10 Marks of the Strong. Any member of that species holding it gets a boosted Core Skill. Contracts can't be undone, and Marks are scarce, so spend them where the boost changes the kit.

💡
Alphas come pre-contracted

An Alpha's core skill is already boosted (the same as 10 Marks), and Alpha status survives evolution. Check the Boost Preview before you spend Marks on a non-Alpha copy. 5:50

Worth the Marks (Game8)

  • Irisalis: +1 clone. "Highly recommended."
  • Fulmintis: Lightning Blade Storm gets more Might, lower EP cost, 20% faster slashes.
  • Stellarys: Shooting Stars fires more stars, higher Damage Boost cap.
  • Thornblade: Thorny Rain grants a Sword Dance stack. GameWith says its kit doesn't work properly until contracted.
  • Tromber: Waltz gains the March buff, replacing Chirpi in the Wind team (enables the Eklue version).
  • Cornet: Wind Bomb Rush drops from 45 to 30 EP with all 3 movement buffs.
  • Fenmane, Sherro (Flowing Water Slash keeps the puddle), Leafy, Waleetle, Grizbo, Magmarex, Squashel.
  • Highly recommended for niche picks: Tuckin, Minespine, Bailite, Nighttime Glynsera.

Skip (Game8)

  • Glacy / Prismana Glacy: heal goes from only 10% to 12% of max HP.
  • Somniwing, Hexxin, Besauce: about 5 to 10 extra EP.
  • Turbo: Nimbi Burst from 10 EP to 0.
  • Blazen: 3 less EP in one state.
  • Scorchhowl, Pawney: mobility only, no damage.
  • Dazmand, Sparkelf, Infergon, Gracewing, Eklue, Helgon, Tubster, Dreaple, Panpanta, Piopiota, Bouldus.
  • Low priority: Fragrancier, Geoclaw, Erlath, Flamerion (good, but after your DPS).

Where to get Marks: the Mysterious Vendor's rotating stock, the Companion Handbook (5 Marks) and the Champion's Gift pack (one contract's worth). Swapping the contracted item off a unit removes the boost until you put it back. 12:12

Pathfinder Talents


Talents belong to your Pathfinder, not to an Aniimo, so they boost every team. Take the damage passives first; they're the three hidden multipliers covered in the damage guide.

🎯
Evolution talents

Four evolutions need a passive talent: Rookey (Unwavering Rampart), Tromber (Magical Horn, from Student III), Bouldus (Peculiar Rock Ball, from Wayfarer II) and Dreaple (Dreamsong). Talents cost Report Cards and open up as your Title rank rises (Magical Horn: Student III, 1 Report Card).

Evolution stages and stones


Lines evolve Lumin → Gamma → Nova (Nova is final; some lines have only two stages). Each step needs a level, usually 3 elemental stones, and sometimes a feat, an item or an Alpha defeat to unlock the branch.

Aniimo evolution screen
Evolution unlocks the Nova stage's kit. Re-check equipped skills afterwards: Sherro's best skill, Flowing Water Slash, has to be equipped again by hand.

Alpha survives evolution

Catch an Alpha early and evolve it; it keeps its pre-boosted core skill. 5:30

Umbral doesn't

Evolving or transforming an Umbral removes the Umbral look. Keep favorite Umbrals unevolved.
