Lex Prime

The Lex Prime is a powerful, accurate pistol that has a low Fire Rate and Magazine Capacity. Built as a crit secondary option for squad clear and mission pressure.

Signature

Lex Prime is not a signature weapon — any frame can use it without a signature passive.

When to Pick

• You want a Pistol that fits a crit secondary play pattern.
• Your loadout needs what Lex Prime does well — check Mission Usefulness below before investing Forma.
• You’re ready to Catalyze / Forma it if you plan to main it on Steel Path.

• Normal Attack

  Impact 18 · Slash 18 · Puncture 144

  Hit-Scan · Crit 25% / 2× · Status 25% · Fire Rate 2.08

• Incarnon Form

  Impact 400 · Radiation 800

  Projectile · Crit 35% / 3× · Status 44% · Fire Rate 0.67 · Projectile 110 · Falloff 10–18m (−33%)

• Normal Attack (Hit-Scan): Impact 18.0, Slash 18.0, Puncture 144.0.
• Incarnon Form (Projectile): Impact 400.0, Radiation 800.0.

Permanent investments on this weapon copy — separate from the Prime variant.

• Orokin CatalystCapacity

  Doubles mod capacity so endgame builds fit.

  Usually the first permanent upgrade on a weapon you plan to main.

• FormaPolarity

  Adds or changes polarities so matching mods cost half capacity.

  Prime polarities help, but expect multiple Forma for a hungry config.

• Exilus Weapon AdapterSlot

  Unlocks utility options (Exilus on guns; melee focuses on stance polarity + utility mods).

  Install when you need ammo, handling, or QoL without sacrificing damage slots.

• Secondary Arcane AdapterArcane

  Lets you install a weapon arcane for a strong passive bonus.

  Worth it once the base mod config is already solid.

• Riven ModRiven

  Unique rolled mod. Disposition 1.2.

  Chase clean desirable stats; skip awkward negatives on low-disposition weapons.

• LexVariant

  The standard version of this weapon — easier to farm, softer stats.

  Use when you don’t want to chase Prime relics yet.

Common building blocks for this gun — not a full ranked build, just the mods you’ll see most often.

  Multishot

  Secondary multishot backbone.

  Viral + Heat remains a safe default.

• Secondary Deadhead / Merciless (Arcane)

  QoL

  Ammo economy for high fire-rate pistols.

Multishot

Usually the highest value damage slot — more projectiles, more procs, more clear.

Critical

Stack crit chance/damage when the weapon’s crit stats justify a crit suite.

Elemental

Faction/elemental lines for Steel Path; Viral+Heat is a safe default on many guns.

Fire Rate

Fire rate raises DPS but burns ammo — pair with reload/ammo economy when needed.
