Your captain's personal space traits are slots you fill yourself, and most of the best ones cost nothing but time. This guide sorts them by what they cost, because that is the order to collect them in. The short version first, then the numbers.
| Build | Traits to slot |
|---|---|
| Any damage build | Precision, Advanced Targeting Systems |
| Energy | Twinkling Lights, Beam Barrage |
| Torpedo | Torpedo Pre-Fire Sequence, Omega Kinetic Shearing, Kinetic Precision |
| Exotic | Particle Manipulator, Particle Generator Amplifier, Auxiliary Power Configuration: Offense |
| Cooldown help | Chrono-Capacitor Array, Unconventional Systems |
| Survivability | Give Your All |
| Support and tank | Into the Breach, Imposing Presence |
Personal traits come from several places: the R&D schools, seasonal events, lockboxes, and species or career. Reputation traits are a separate set of slots. Each reputation unlocks two traits per tier, and you get four passive space reputation slots by default, with a fifth buyable at the Fleet Research Lab. You can reassign both kinds in a social hub or in sector space, so nothing here is a permanent choice. The figures below are Rank I. When a reputation reaches Tier VI, Rank II of its traits becomes available and the buffs grow. For how to climb the tiers, see Navigating the Reputation System.
These cost only the time to earn the reputation, and they are the backbone of almost every build.
The STO BETTER projectile and exotic guides both list Precision and Advanced Targeting Systems as traits to always slot, and the crit stats help every build that can reach a high critical chance. Magnified Firepower, a flat +5% weapon damage from Gamma Task Force at Tier IV, is the filler pick when you still have a slot free.
Two reputation traits depend on your ship. Tyler's Duality gives +1% critical chance based on hull capacity, up to +6 at 200,000, so it is worth it on tough ships and weak on fragile ones. Controlled Countermeasures gives +7.5% energy weapon and projectile damage against controlled targets, so it needs control abilities to pay off.
Raising an R&D school to level 15 unlocks a personal trait tied to that school. After you reach it, you need to relog or change map before the trait appears. The R&D system itself opens at captain level 15, and level 15 in a school takes 630,000 school experience, so this is a long project, but it costs no money.
Twinkling Lights gives -20 all damage resistance rating on a foe for each direct energy weapon type you use on it, until it is defeated. Fire at Will and Scatter Volley can spread it to extra targets. It comes from the winter event, and STO BETTER recommends it for most energy builds, even ones that use a single weapon type. A build that mixes several energy types wants it most.
Lockbox traits are sold on the Exchange, so you pay in energy credits and not with a grind. Three are worth knowing.
Fill your reputation slots first, because those are free and strong. Then add the R&D trait that matches your build, then Twinkling Lights if you fly energy, and only then consider a lockbox trait.
A torpedo boat takes the torpedo reputation traits, as laid out in Torpedo Boat Fundamentals. An energy ship follows the layout in The Anatomy of a Meta Energy Build. A tank leans on Give Your All and Imposing Presence, which raises threat and is open to any captain, as covered in Tanking Advanced and Elite TFOs. If cooldowns are your bottleneck, read Cooldown Reduction Mechanics.
These are your own traits. The traits on your ship are a separate set, covered in Must-Have Starship Traits for Every Build. The Build Planner has a Traits tab where you can try these combinations against your build before you earn any of them.
