Mods, catalysts and crafting

Mods are the equipment of your flagship. They drop from battles, can be bought at the station market or built in the fabricator, and are ranked up with credits or scrap. This guide covers tiers, every mod, catalysts and crafting.

Tiers

  • Common×1 strength
  • Uncommon×1.15 strength · 1 bonus line
  • Rare×1.35 strength · 1 bonus line
  • Epic×1.6 strength · 2 bonus lines
  • Legendary×1.9 strength · 3 bonus lines
  • Uniqueone-of-a-kind pieces with their own effect

Higher tiers are stronger and carry extra bonus lines. Legendary pieces are rare: less than one drop in a hundred.

Unique mods double their main stat (Legendary ×1.9) and carry a fixed second stat instead of random lines: Gatebreaker critical chance, Ember Choir primary damage, Overflow Lattice shields, Wingmother’s Oath energy, Meridian Charter hull and Jumpwake Coil ability cooldowns. At the highest rank with a perfect roll, Gatebreaker gives up to +101% primary damage and Wingmother’s Oath up to +115% escort strength. Bosses drop them, and the relic forge makes any of them from relic shards.

Stat rolls and roll grades

Two copies of the same mod are not the same piece. Every piece rolls its main stat (its quality) and each of its bonus lines inside a range set by its tier, so a higher tier always rolls higher, and high rolls are rarer than low ones.

TierMain stat (quality)Each bonus line, of a full line
Common80–110%50–80%
Uncommon85–112%55–85%
Rare88–115%62–92%
Epic92–118%72–100%
Legendary96–120%84–112%

Each piece also shows a roll grade: how well it rolled for its tier, from Low through Solid, Strong and Near perfect to Perfect. The main stat counts twice, each bonus line once. Bonus lines that rolled near the top of their range are marked ✦. A Low Legendary still beats a Perfect Rare, because the tier sets the range and the grade only says where in it the piece landed. Sort the hangar by roll grade to find your best copies, reforge the bonus lines of a good piece, or use an Ascendant spark to raise it a tier (its lines rise to the new tier’s floor).

When a Legendary mod drops, a pillar of light slams down where it fell and the battle slows for a moment. Pick it up and its rolled stats and grade appear in the centre of the screen.

Catalysts

Catalysts change a piece you already own:

  • Reforge cell: new stats, new values. A clamped line stays.
  • Stasis clamp: the one bonus line you choose is held in place.
  • Ascendant spark: one spark to Uncommon or Rare, two to Epic, four to Legendary. It keeps its lines and rolls the new ones the tier adds.
  • Veil shard: no catalyst touches it again.

Crafting and breaking down

The fabricator at Meridian Station builds the exact mod you want from scrap and exotic matter, including the craft-only mods above. Mods you do not need can be broken down for scrap; set the break-down filter so low tiers are recycled automatically.

Which copy is better? The fit score

Every piece in the hangar shows a ★ fit score: how much that piece adds to your build for the build focus you picked above the list (Balanced, Firepower, Survival, Abilities, Mobility, Escorts or Salvage). It is the one number to compare. Higher is better, whatever the tier, the quality or the roll grade.

When you own more than one copy of a mod, the spare copies say it in words: “▼ Weaker than your fitted Epic copy · fit score 0.21 vs 2.62 (−92%) · safe to recycle”, or “▲ Stronger than your fitted Common copy … tap Replace fitted”. The Compare other copies line tells you whether they are weaker or stronger before you even open it.

The other chips answer different questions:

  • Q 110% (quality): the piece’s main stat as a share of a full value for its tier. A Q 110% Common is still smaller than a Q 99% Epic, because the Epic’s full value is bigger.
  • Perfect for Common, Solid for Epic (roll grade): how lucky the piece was compared with pieces of the same tier only.
  • ✓ best fit: the piece the game would fit for your focus.

What to fit

  • Pick a build focus in the hangar and press Fit best: the game fits the pieces with the highest fit score, one per mod family.
  • Or start from a play style: each is built around a unique mod, and Fit for this style fits your best pieces for it.
  • Pieces that boost your main gun matter most for strikers and artillery; escort and ability pieces matter most for carriers and support ships.
  • Rank up the pieces you keep, not every drop, and recycle the copies marked “safe to recycle”.
