Info

  • Vex Armor is Chroma’s ability 3.
  • Chroma fortifies squad Armor when his Shields are damaged or he kills an enemy with a melee weapon.
  • Use it with the rest of the kit — especially Spectral Scream, Elemental Ward — instead of casting it in isolation.
  • Ability Strength, Duration, Range, and Efficiency each matter differently; check Mod Scaling below before dumping all four.

Cast Changes

  1. Modifies Vex Armor with: Vex Armor Augment: Chroma reduces the damage his squadmates within Affinity Range take by 75%.
  2. Rank up the augment to unlock the full effect values.
  3. Costs a mod slot (and capacity) — only equip it when the change matters for your loop.

Worth the Slot?

  1. Worth it when the augment’s change is central to how you play Chroma.
  2. Skip it if the base Vex Armor already does what you need and you’d rather keep the slot for survivability or strength.

Tips & Tricks

  • Read the battlefield first — cast Vex Armor when it actually solves the room, not on cooldown habit.
  • Pair Vex Armor with movement and energy economy so you’re not stranded after a big spend.
  • On Steel Path, confirm whether Vex Armor still carries without strip, Viral, or a squad buff.
  • If you never press 3, it’s the first Helminth candidate on Chroma.

Mod Scaling

Strength

Improves Vex Armor’s damage or effect potency where Strength is listed on the ability.

Duration

Duration is low priority on Vex Armor unless an augment or lingering effect needs it.

Range

Increases Vex Armor’s reach, radius, or targeting distance.

Efficiency

Vex Armor costs energy each cast — Efficiency (or strong regen) keeps the loop comfortable on long missions.

Priority

Stack the stats that actually move this ability’s needle, then Efficiency for uptime.

Mission Use Cases

MissionHow to Use It
Steel Path Survival / Defense / DisruptionTest whether Vex Armor still clears or enables clear when enemies are dense and overlevelled.
Mobile Defense / ExcavationUse Vex Armor to control or delete the swarm on the objective, then reposition.
Exterminate / Capture Speed RunsCast Vex Armor only when it saves time — skip it on empty tiles.
Spy / Rescue / Quiet RoutesIf Vex Armor is loud or forces combat, save it for after the vault; if it’s stealth-friendly, use it to stay safe.

Comparisons

  • VS

    Vs similar tools on other frames — Vex Armor is tuned for Chroma’s loop — don’t judge it as a standalone subsume without the rest of the kit.
