Star Sailors is a collectible turn-based RPG where your success depends heavily on which Partners you invest in. With 23 gacha-summonable characters split between Battle Partners and Assist Partners, plus elemental synergies and role combinations to consider, new players can quickly feel overwhelmed by choice.

This guide ranks the confirmed top performers based on current beta and early access testing. Use it to decide who deserves your resources first, and which characters can carry you through the early game while you hunt for premium pulls.

How This Ranking Works

Characters are evaluated on overall viability across PvE content, boss fights, and PvP scenarios. The best picks typically excel in at least two of these areas:

  • Chain building speed - how quickly they contribute to combo chains that amplify team damage
  • Survivability or team protection - tanks and healers that prevent wipes in difficult content
  • Burst or sustained damage - raw output for clearing waves or burning down bosses
  • Utility and debuffs - buff stripping, defense breaks, and crowd control that enables the whole team
  • Elemental flexibility - how well they fit into strong team synergies

Rankings reflect the current meta and may shift as balance patches arrive. Fire and Light elements currently dominate many top-tier compositions, but elemental advantage mechanics mean no single element wins every fight.

Star Sailors Character Rankings

Tier Recommended Picks Why They Stand Out S Tier Jen, Heidi, Nina, Kaira, Carat, Hunter K, Iris, Gerbil Exceptional chain building, survivability, and burst potential. These units carry teams through endgame content and work in multiple team types. A Tier Erling, Ethan, Sion, Mui, Dora, Jerry, Simo Strong performers that need specific setups or elemental teams to reach full potential. Worth building if you have the right supports. B Tier Rak, Soul, Nutty, Iron, Caroline, Remi, Media, Ed Usable early-game options that fall off without heavy investment. Replace with S or A tier when possible.

S-Tier Characters Worth Building First

Jen (Fire Defender/Healer)

Jen is the anchor every team wants. She provides steady healing, reduces damage taken by allies, and strips enemy buffs to break boss defenses. Her ultimate deals heavy AoE damage while boosting her healing bonus by up to 20%. In prolonged fights where sustain matters, Jen is currently unmatched.

She pairs especially well with Heidi and Nina in Daylight Fire compositions, protecting your damage dealers while they build chains.

Heidi (Fire Attacker)

The best AoE damage dealer in Star Sailors. Almost all of Heidi's abilities hit multiple enemies, and her ultimate cranks her ATK bonus up to 220% while adding crit rate. She excels at building chains quickly through multi-hit skills, making her devastating in debuff-focused teams.

Her scaling in Fire teams is particularly strong. If you pull Heidi early, build around her immediately.

Nina (Attacker)

When you need single-target elimination, Nina delivers. Her self-buffing crit rate and skills like Hook Shot and Grey Zone let her dominate bosses and elite enemies. She finishes chain-boosted combos with immense reliability.

Nina synergizes exceptionally with Hunter K in Earth team compositions, where his crit buffs and auto-attack triggers amplify her already brutal output.

Kaira (Light Support/Sub DPS)

Kaira solves the problem of needing healing without sacrificing damage. She offers spot healing, team-wide HP restoration through her ultimate, and up to 15% ATK buffs for allies. Against bosses with intense damage phases, she keeps the team alive without requiring a full support slot.

Her Twilight flexibility also lets her slot into hybrid teams outside pure Light compositions.

Carat (Fire Attacker)

A rare F2P-friendly S-tier option. Carat brings crit buffs and a devastating 3-hit 330% ATK burst skill that scales well from early to late game. She bridges the gap while you hunt for premium pulls, and pairs surprisingly well with Wind supports like Mui.

Her elemental advantage consistency makes her reliable even when you cannot field a full Fire team.

Hunter K (Earth Support/DPS)

Hunter K boosts team crit rate, enables auto-attacks on ally turns, and provides SP recovery. In Earth teams with Nina and Jerry, he creates a self-sustaining damage engine that rarely runs out of resources.

His value is slightly more team-dependent than pure solo carries, but in the right composition he elevates everyone around him.

Iris (Light Attacker)

Iris deals massive off-field damage without occupying the active slot, making her perfect for crit synergy setups with Brute Strike. She essentially gives you a free damage source while your main team handles other priorities.

This off-field presence is uniquely valuable in content with tight turn limits or positioning restrictions.

Gerbil (Debuffer)

Defense stripping is essential for high-level bosses, and Gerbil is the best at it. He enables your entire team's DPS by breaking enemy defenses, and contributes meaningful damage from off-field positions.

If you are struggling with tanky bosses despite good gear, Gerbil is usually the missing piece.

A-Tier Characters for Specific Teams

These picks perform at near-S-tier levels when supported correctly, but need more careful team building.

Erling is a reliable Water defender with strong survivability. He works best as a secondary tank in Midnight team compositions where his protection abilities complement rather than replace your main anchor.

Ethan serves as a solid F2P Light attacker for early game clears. His burst potential is decent in Daylight team comps, though he eventually gets outscaled by premium options.

Mui excels as a Wind buffer and healer specifically for Carat teams and Daylight Wind compositions. Without those synergies, her value drops noticeably.

Jerry provides strong off-field Earth DPS that completes the Nina-Hunter K core. Do not build him in isolation, but prioritize him highly if you already have that duo.

B-Tier and Below: Early-Game Bridges

Characters like Rak, Soul, and Remi appear frequently in early summons and story rewards. They are functional for chapters 1-3, but resist the temptation to over-invest.

Rak works as a Fire Midnight tank for early content, yet struggles in prolonged or AoE-heavy fights where Jen would thrive. Soul offers decent Fire DPS for early bossing but falls off mid-game without heavy investment. Remi is the free starter tank with a team shield that simply does not scale.

Use these units while you need bodies on the field, then replace them with S or A tier picks as soon as your gacha luck permits.

Element and Role Priorities

Based on current team composition data, Fire and Light elements dominate the top tier lists. Fire offers the strongest pure damage stacking through Heidi, Jen, and Carat. Light provides the best hybrid support-damage combinations with Kaira, Iris, and Ethan.

Water, Wind, and Earth have viable options but require more specific team investments to compete. Earth teams with Nina, Hunter K, and Jerry can match Fire output, but need all three pieces to function.

For roles, prioritize in this order:

  1. Main damage dealer with chain building (Heidi, Nina)
  2. Team anchor with healing or protection (Jen, Kaira)
  3. Defense stripper or debuffer (Gerbil)
  4. Off-field damage or support (Iris, Hunter K)

What to Build First

If you are just starting, your first goal is securing any S-tier damage dealer. Heidi or Nina should be your primary reroll targets. Once you have one, immediately build Jen or Kaira as your team anchor.

Do not spread resources across multiple elements early. Commit to one strong elemental core and build synergy within it. A complete Fire team with Heidi, Jen, and Carat will outperform a scattered collection of S-tier units from different elements.

Save your premium upgrade materials for confirmed S-tier picks. The resource cost to max a character is substantial, and B-tier investments are effectively wasted progress.

Check the official website and in-game notices for balance updates that might shift these rankings as the game evolves.
