Info

Radial Javelin is Excalibur Umbra’s ability 3.
Radial javelins impale nearby enemies, inflicting Slash Status.
Use it with the rest of the kit — especially Slash Dash, Radial Howl — instead of casting it in isolation.
Ability Strength, Duration, Range, and Efficiency each matter differently; check Mod Scaling below before dumping all four.

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 Umbra.

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.

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

Mission	How to Use It
Steel Path Survival / Defense / Disruption	Test whether Radial Javelin still clears or enables clear when enemies are dense and overlevelled.
Mobile Defense / Excavation	Use Radial Javelin to control or delete the swarm on the objective, then reposition.
Exterminate / Capture Speed Runs	Cast Radial Javelin only when it saves time — skip it on empty tiles.
Spy / Rescue / Quiet Routes	If Radial Javelin is loud or forces combat, save it for after the vault; if it’s stealth-friendly, use it to stay safe.

VS
Vs similar tools on other frames — Radial Javelin is tuned for Excalibur Umbra’s loop — don’t judge it as a standalone subsume without the rest of the kit.
