  • Use it with the rest of the kit — especially Slash Dash, Radial Blind — 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 Radial Javelin with: Radial Javelin Augment: Each enemy hit will increase Excalibur's Melee Damage by 15% for 16s.
  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 Excalibur.
  2. Skip it if the base Radial Javelin already does what you need and you’d rather keep the slot for survivability or strength.

Tips & Tricks

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

Mod Scaling

Strength

Strength matters if Radial Javelin scales effect power; otherwise dump it for other stats.

Duration

Duration is low priority on Radial Javelin unless an augment or lingering effect needs it.

Range

Increases Radial Javelin’s reach, radius, or targeting distance.

Efficiency

Radial Javelin 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 Radial Javelin still clears or enables clear when enemies are dense and overlevelled.
Mobile Defense / ExcavationUse Radial Javelin to control or delete the swarm on the objective, then reposition.
Exterminate / Capture Speed RunsCast Radial Javelin only when it saves time — skip it on empty tiles.
Spy / Rescue / Quiet RoutesIf Radial Javelin 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 — Radial Javelin is tuned for Excalibur’s loop — don’t judge it as a standalone subsume without the rest of the kit.
