Star Sailors Tier List (July 2026) – Best Partners Ranked

The best Partners in Star Sailors are Heidi (S Tier - exceptional AoE Fire damage that scales with Fired Up stacks and reduces enemy Fire RES by up to 15%), Kaira (S Tier - strongest offensive buffer in the game at +22% ATK for all allies with built-in healing), and Hunter K (S Tier - universal 33% ATK boost with SP Recovery generation that fits into any team). This tier list ranks all 23 Battle and Assist Partners by DPS, Skills, healing, and late-game scaling.

Star Sailors is a turn-based RPG built around assembling teams of Battle and Assist Partners to collect and build powerful, high-synergy teams. With every partner having a distinct role, the difference between a well-built team and a randomly assembled one becomes obvious quickly. Some partners work in almost any composition, while others rely on combo setups or thresholds that narrow their usefulness. So, to help you pick the best ones, this tier list ranks every Battle and Assist Partner.

What Do the Tier Rankings Mean in Our Star Sailors Tier List?

In our Star Sailors Tier List, we have ranked the partners based on overall performance across DPS, team buffing, healing, debuff application, and how much setup each partner requires. Below, we've provided a detailed breakdown of each tier:

Tier	Meaning in Star Sailors	Partners
S	The strongest partners in the game. Exceptional damage, team buffs, healing, and skills that hold up across every stage without needing specific compositions.	4
A	Excellent partners that perform very well in most situations with high damage or strong support value, though most require specific team conditions or setups.	8
B	Solid partners that clear early-to-mid game content comfortably, but are more situational and depend on specific setups to perform well.	6
C	Niche partners that can contribute in specific teams but are generally outclassed by higher-tier options, requiring more setup for less overall return.	5

Which Partners Are S Tier in Star Sailors?

Partner & Type	Element	Why This Tier	Best For
Heidi [Battle Partner]	Fire	+ Heidi deals exceptional AoE damage with an additional 110% Final ATK multiplier, capable of wiping multiple enemies simultaneously in late-game waves. + Her Flare Up debuff reduces enemy Fire RES by 3% per application, amplifying both her own output and the entire Fire team's DPS. + Fired Up stacks accumulate whenever any ally applies a debuff, which means her damage ceiling only gets higher the longer a fight goes.	All content, Fire teams, Late-game AoE DPS
Kaira [Battle Partner]	Light	+ Kaira provides the strongest offensive buff in the entire roster, increasing every ally's ATK by 22% for 3 turns in a single skill. + Her Ultimate applies Strong Enemy to all enemies, increasing damage received by 15%, while simultaneously restoring HP equal to 30% of Final ATK to every ally. + She also scales into the late game through Zeal stacks, gaining 3% ATK per stack as battle progresses.	All teams, mid-to-late game, DPS teams
Hunter K [Assist Partner]	Earth	+ Hunter K grants an ATK increase equal to 33% of his own ATK to either a single high-priority ally or the entire team, making him the strongest universal offensive support currently available. + His Trait and Ultimate generate frequent SP Recovery, letting teammates use skills and Ultimates significantly faster. + On top of that, he grants 22% DEF and 15% RES to all allies for 3 turns, covering survivability without needing a dedicated tank slot.	All teams, Support, Buffing
Dora [Assist Partner]	Water	+ Dora provides the strongest raw healing in the game at up to 50% of her Final HP restored to every ally, and applies emergency heals to low-HP teammates before they reach a critical threshold. + Her Ultimate also increases all allies' ATK by 30% for 3 turns, covering both sustain and damage amplification in one skill. + Passive HP restoration on every allied turn further reduces SP pressure by keeping the team healthy without needing dedicated healing actions.	All teams, Healing, Support

Which Partners Are A Tier in Star Sailors?

Partner & Type	Element	Why This Tier	Best For
Soul [Battle Partner]	Fire	+ Soul's Ultimate triggers multiple times based on his current HP threshold, with each dealing more total damage, making him a strong single-target DP. + His Trait restores HP equal to 60% of Final ATK whenever he attacks, helping him stay above the 50%, 75%, and 100% HP thresholds required for peak Ultimate damage.	Boss fights, Core Burst DPS
Erling [Battle Partner]	Water	+ Erling's Mean Bubble debuff reduces enemy RES by 5% per stack while Pretty Bubble lowers Heal Bonus received by 10%, making her one of the best anti-sustain debuffers available. + She provides team-wide Shields equal to 22% of her DEF, healing equal to 15% of her DEF, and +1 SP Recovery per debuff application, covering multiple support roles simultaneously.	Debuffing, Support, Mid Game
Iris [Assist Partner]	Light	+ Iris increases all allies' Crit DMG by 30% for 3 turns and enters battle with 5% Crit Rate and 10% Crit DMG already active, one of the highest offensive crit buffs any Assist Partner provides. + She also amplifies damage during Chain combos. The limitation is that her value drops sharply in teams without a crit-focused primary DPS, making her strong in the right composition.	Sustained DPS, Support
Mui [Assist Partner]	Wind	+ Mui increases the entire team's HP equal to 50% of her own HP, applies Gaze to increase all stats by 5% per ally, and removes 1 debuff from every teammate while reducing incoming damage by 15% for 2 turns. + This combination of bulk sustain, stat amplification, and debuff cleansing makes Mui strong in later waves where multiple overlapping debuffs can otherwise cripple a team.	Support, Healing
Nutty [Assist Partner]	Earth	+ Nutty's Curiosity Triggered debuff increases enemy DMG Received by 3% per stack and she generates +1 Chain Bonus and +1 SP Recovery whenever a debuff is applied, helping teams maintain offensive pressure in combo setups. + Nutty's own damage output is low since most of her value comes from buffing teammates, but the combination of enemy vulnerability increase and SP generation is great in most compositions.	Debuffing, Buffing, Support
Jerry [Assist Partner]	Earth	+ Jerry copies 50% of an ally's Additional DMG through Bravo, meaning his burst potential scales directly alongside whatever DPS unit he's paired with. + His Ultimate grants 3 Bravo stacks instantly, enabling explosive follow-up damage during burst windows without requiring lengthy setup.	Secondary DPS, Sustained DPS
Nina [Battle Partner]	Earth	+ Nina's Ultimate deals strong single-target burst damage with Foresight guaranteeing a Critical Hit for additional damage equal to 55% Final ATK, and Foresight refreshes automatically whenever she crits. - The clear limitation is her complete reliance on single-target output, giving her almost no value in multi-enemy waves where AoE dealers like Heidi pull dramatically ahead.	Boss fights, Burst DPS
Jen [Battle Partner]	Fire	+ Jen grants 22% DEF to herself while absorbing 50% of incoming ally damage to protect low-HP teammates, functioning as one of the most reliable frontline protectors in the current roster. + Her Ultimate deals 165% damage based on Final DEF and converts accumulated World Tree's Seed stacks into team-wide healing, sustaining the team through prolonged fights.	Tank, Support, Mid Game

Which Partners Are B Tier in Star Sailors?

Partner & Type	Element	Why This Tier	Best For
Ethan [Battle Partner]	Light	+ Ethan provides Shields equal to 20% of Final ATK, HP restoration between turns, and an Ultimate that deals 330% Final ATK damage while stripping all enemy Shields. - Several of his abilities require him to maintain an active Shield state to function correctly, which reduces his consistency when the Shield breaks.	Early Game, Support, Secondary DPS
Rak [Battle Partner]	Fire	+ Rak is a durable HP-scaling tank who applies Taunt to redirect enemy targeting and deals HP-based damage while gaining Chain Bonus whenever struck during Fiery Heart. - His DPS depends on enemies staying Taunted, which limits his burst damage potential in situations where taunt breaks early or enemies resist its application.	Tanking, Secondary DPS, Mid Game
Simo [Assist Partner]	Wind	+ Simo consistently reduces enemy RES by up to 20% through his Ultimate and generates Chain Bonus whenever applying debuffs, fitting into combo-focused team setups. - He provides almost no passive outside of Resistance reduction, making him significantly less versatile than higher-tier Assist Partners that cover multiple roles.	Debuffing, Early Game
Sion [Assist Partner]	Light	+ Sion increases Chain Mastery by 30% for all allies and restores SP whenever Chain Hits occur during extended fights, making her valuable in compositions that perform well in combos. - Her contribution falls sharply in teams that don't generate Chain Hits consistently, which narrows the team compositions where she is worth slotting over a more flexible support.	Support, Combo Teams
Gerbil [Assist Partner]	Light	+ Gerbil's Sonata of Truth increases enemy DMG Received by 15% while reducing RES by 10%, and she generates multiple Chain Bonus stacks through her Trait and Ultimate to maintain combo pressure. - Her effectiveness depends on debuffs remaining applied. When they aren't, her contribution is minimal and she becomes easily replaceable by supports that deliver unconditional value.	Support, Buffing, Mid Game
Carat [Battle Partner]	Wind	+ Carat deals solid burst damage through her Ultimate and gains increased Crit Damage during Chill Diva state, making her a real threat in boss wave encounters. - Most of her meaningful output is tied to Ultimate usage, which reduces consistency during longer skill rotations where the Ultimate is on cooldown and her base kit fills the gaps less effectively.	Boss waves, Burst DPS, Secondary DPS

Which Partners Are C Tier in Star Sailors?

Partner & Type	Element	Why This Tier	Best For
Iron [Battle Partner]	Earth	+ Iron provides excellent defensive value through 20% HP Shields, 30% team HP Shields, a 20% MAX HP increase, and self-healing, making him the most durable frontline tank available. - His offensive contribution is too low to justify the roster slot in compositions that need damage. - His Ultimate only deals 220% damage, and the Iron Will Trait requires taking repeated hits before its Shield effect activates.	Tank, Early to Mid Game
Remi [Battle Partner]	Earth	+ Remi grants Shields equal to 30% of Final DEF and Sturdy, reducing Critical Hit damage taken by 15% for all allies. - Her entire kit revolves around defensive utility with almost no DPS, she only deals damage through her Ultimate, making her a poor choice for compositions that need any DPS.	Tanking, Support, early-game only
Caroline [Assist Partner]	Fire	+ Caroline reduces enemy ATK by 20% and DMG Dealt by 30%, which improves team survivability meaningfully against later early-game waves. - She delivers only defensive debuffs with nothing to amplify ally damage, and her skills directly overlaps with stronger Assist Partners that provide both offensive and defensive effects.	Tanking, Debuffing, early game
Ed [Assist Partner]	Fire	+ Ed removes 1 debuff from allies, restores 30% HP based on ATK through his Ultimate, and increases Additional DMG by 30% for 3 turns. - His healing output falls below what dedicated healers like Dora and Mui provide, and his strongest buff only benefits compositions that already deal Additional Damage.	Debuffing, Early Game
Nadia [Assist Partner]	Water	+ Nadia's Brush Trace debuff increases enemy DMG Received by 5% per stack, providing a gradual damage boost in the early stages. - She requires multiple applications to fully stack the debuff, which delays her contribution in shorter encounters. - Her kit provides minimal healing or offensive buffs compared to every higher-tier Assist Partner.	Early-game, Debuffing, Buffing
