How many partners are in Star Sailors?
20 Partners at launch. 16 are obtainable without premium Gold Compass.

Star Sailors Partners are the collectible characters that fight alongside your Adventurer. The game uses the term Partners (not Heroes). Search star sailors characters, star sailors partners, or star sailors all characters — this guide maps every launch roster entry with obtainment routes and tier labels.
Official launch data lists 20 Partners, with 16 obtainable without premium Gold Compass through story, login rewards, Compass Expedition Rally, and events. The remaining units chase banner SSR at 2% rate with 100-pull pity.
Each Partner has a Battle or Assist slot type, one of six elements, a class role (Attacker · Defender · Supporter · Debuffer), and a trait window (Daylight · Midnight · Twilight). Tier badges reflect community PvE meta — confirm on the tier list before investing.
Pair this Star Sailors partners guide with the wiki partner grid, teams guide, and reroll guide for full account planning.
Battle Partners fight on the field with your Adventurer. They spend SP on active skills, deal direct damage, tank hits, or cast heals during turns. You equip two Battle Partners per team.
Assist Partners stay off-field. A portion of their stats converts into team-wide bonuses — Chain amplification, crit buffs, healing aura, or debuff extension. You equip two Assist Partners per team. An S-tier Assist like Gerbil or Hunter K can outvalue a mediocre third Battle unit.
Only three units appear on the battlefield: Adventurer + 2 Battle Partners. Assists shape Combat Power through passives and converted stats even though they never animate on field.
Slot the wrong type and you lose damage — putting only Attackers in both rows without an Assist healer fails long boss fights. The teams guide enforces one Break dealer, one sustain Assist, and element coverage.
| Type | On field? | Best for | Examples |
|---|---|---|---|
| ⚔️ Battle | ✅ Yes | DPS · tank · active heal | Nina · Jen · Heidi |
| 💫 Assist | ❌ Off-field | Buff · debuff · Chain | Gerbil · Dora · Iris |
Every Star Sailors Partner carries a class role and element that determine team synergy. Cover multiple elements per squad for Chain Bonus and stage advantage.
Attacker — raw damage and crit scaling. Heidi, Nina, Carat, Iris (Assist), Ethan. Prioritize for story DPS.
Defender — mitigation, shields, and damage sharing. Princess Jen, Erling, Rak, Remi, Iron. Anchor boss teams.
Supporter — heals, buffs, and SP recovery. Kaira, Quarter Rest Dora, Mui, Hunter K, Ed. Required for sustain.
Debuffer — strips buffs, applies Flare Up and Strong Enemy states. Caroline, Gerbil, Nutty, Simo, Nadia. Pairs with Heidi fire comps.
Elements — Fire, Water, Wind, Earth, Light, Dark. Early story weak to fire makes Caroline and Heidi strong in chapters 1–3; Ethan and Kaira shine in light-heavy chapters 4–5.
Traits — Daylight, Midnight, Twilight time windows grant small bonuses when matched across the team. Nice-to-have early, important for raid min-max.

Free-route SR staples — Quarter Rest Dora (heal Assist), Mui (wind buffer), Jerry and Nutty (earth Assists), Rak and Soul (fire Battle), Simo (wind debuff Assist), Ed (fire support Assist), Remi and Iron (earth defenders).

Star Sailors Partner investment follows role priority, not roster size. Spreading Gold across twelve units bricks Combat Power.
Step 1 — Max one Battle DPS first: Heidi, Nina, or Carat (budget). Level to story cap before touching supports.
Step 2 — Level one sustain unit: Kaira, Princess Jen, or Quarter Rest Dora. Long fights fail without healing or damage share.
Step 3 — Promote one Assist: Gerbil, Hunter K, or Mui. Assists gain value from Promotion even off-field.
Step 4 — Skill upgrades on carry only. Caroline benefits from debuff skill levels; Nina from burst skills.
Step 5 — Memory and Gear on carry Partner — four-piece sets before second DPS. See beginner guide resources.
Never promote C-tier placeholders (Remi, Nadia) past story minimum — replace with SSR before spending rare stones.

|---|---|---|---|
| 1 · DPS | Battle Attacker | Heidi · Nina · Carat | Story CP met |
| 2 · Sustain | Battle/Assist heal | Kaira · Dora · Jen | Boss stable |
| 3 · Assist | Chain / crit | Gerbil · Hunter K | Raid ready |
| 4 · Second DPS | Element coverage | Ethan · Soul | Banner SSR pulled |
