Star Sailors Nina Build: Best Gear, Memories & Team

Nina is one of the strongest single-target carries in Star Sailors. She deletes bosses and elite enemies with brutal crit damage. If you rerolled for her or pulled her early, this guide covers her full build. We will keep it practical and based on how she actually plays, not on theory alone.

Whether you're playing on a high-performance computer, a low-end PC, or a Mac, optimizing your settings can significantly improve your experience. In this guide, we'll cover the recommended PC specifications, performance optimization tips, graphics settings, and how to play Star Sailors PC with MuMuPlayer.

Who Nina Is

Nina is an SSR Earth Battle Partner in the Attacker role, and she sits in the Daylight faction. Her whole kit revolves around crit hits and a mechanic called Foresight. Unlike Heidi, who clears whole waves, Nina wants one big target to focus down.

How Nina Actually Works

Here is the mechanic that decides her whole build. Nina's trait grants Foresight whenever she lands a crit. Foresight then turns her next action into a guaranteed crit. That crit grants Foresight again.

So she builds her own crit loop. Once it starts, she almost never drops a crit. This is why we do not stack crit rate blindly. You need just enough crit rate to start the loop. After that, crit damage carries her scaling.

Her passive gives 7% crit rate on battle entry. Her buff skill layers on more. That built-in crit rate is exactly why gear priorities shift toward damage over reliability.

Nina's Skills Explained

Here is the full kit so you can see how the loop connects. Every skill either applies Foresight, consumes it, or cashes in on the guaranteed crit.

Skill	Type	SP	Effect
Basic Attack	Charge	Gains 1-2 SP	Hits one enemy for 55% ATK
Zugzwang	Attack	4 SP	Two hits for 88% ATK. In Foresight, adds 55% ATK damage and 15% crit rate
Advanced Chess	Buff	5 SP	Grants Foresight for 1 turn and 10% crit rate for 3 turns
Checkmate	Ultimate	12 SP	Three hits for 330% ATK. In Foresight, adds 55% ATK damage. Consumes Foresight
Trait	Passive	None	On crit, grants Foresight
Passive	Passive	None	On battle entry, grants 7% crit rate

Notice the pattern. Advanced Chess plants Foresight, so your next hit crits for sure. That crit refreshes Foresight through her trait. From there she just keeps the loop rolling.

Skill Priority

Level her ultimate first, since it carries most of her single-target burst at 330% ATK. Her buff skill comes second because it feeds Foresight and crit rate. Her attack skill is third. Do not waste materials leveling every skill early.

• Ultimate (Checkmate): highest priority

• Buff (Advanced Chess): second, sets up the Foresight loop

• Attack (Zugzwang): third

• Basic attack: leave it alone

Best Memory Pieces

Memory Pieces act as Nina's signature gear layer. They give her the single biggest boost you can equip.

Memory Piece	Rarity	When to Use
Traitor	SSR	Best in slot, use it if you own it
Silver Ravens Leader	SR	Strong free-to-play alternative

Traitor is her clear best option. If you do not have it, Silver Ravens Leader holds up very well. Plenty of other attacker memories exist. Most of them carry conditions that do not fit Nina, so we skip those.

Best Gear Sets

This is where builds split, and both paths are valid. The database-style build runs one full four-piece set. Many veteran players run a hybrid instead.

Build	Setup	Why It Works
Standard	4-PC Still Abyss	Earth damage plus crit rate after ultimate
Hybrid	2-PC Solemn Resolve + 2-PC Still Abyss	Permanent 15% ATK plus 10% Earth damage

Here is our honest take. Still Abyss at four pieces grants 10% crit rate after your ultimate. But Nina already floods herself with crit rate from her kit and from Hunter K. That extra crit rate often overcaps and goes to waste.

The hybrid gives a flat 15% ATK that never switches off. For most accounts, that steady attack beats a situational crit rate spike. Blessing of Primordial Tan also serves as a solid four-piece attack option if you lack Solemn Resolve pieces.

Main Stats and Sub Stats

Your head, top, and bottom pieces roll fixed main stats. You only choose the ring and necklace, so choose well.

• Ring: Earth DMG% (preferred) or ATK%

• Necklace: Crit DMG% once your crit rate sits high

• Sub stats: ATK%, Crit DMG%, then Crit Rate% only if needed

We lean toward an Earth damage ring. Element damage acts as a separate multiplier on a mono-Earth carry. It stacks cleanly on top of her attack buffs, while ATK% has to compete with every other attack source.

For the necklace, crit damage usually wins. Since Nina self-generates crit rate, a crit rate necklace tends to overcap. Only run crit rate if you still sit well below 100% crit inside actual fights.

Best Team for Nina

Nina slightly underperforms her hype when she stands alone. She needs her Earth core online to truly shine. Build these two around her first.

• Hunter K: the premier support in the game. He converts a large share of his own attack into a team-wide attack buff, and he raises crit rate.

• Jerry: off-field Earth damage that completes the core. Build him with heavy Chain Mastery for maximum output.

For the Adventurer slot, an Earth main character keeps the team mono-element. That improves Chain Mastery synergy across the board. If your team keeps dying, a defender or a flexible support like Kaira fits nicely instead.

A clean Nina lineup looks like this: Nina, Hunter K, and Jerry, plus an Earth Adventurer and one defender or support in the flex slot.

Conclusion

Nina rewards patience more than most carries in Star Sailors. On her own, she can feel average, and that trips up a lot of new players. With Traitor, the right gear, and her Earth core, she becomes a boss-deleting machine.

Start her crit loop, pivot into crit damage, and let Hunter K feed her attack. Do that, and very few bosses will survive her focus fire.
