Playstyle

Excalibur Prime is the primed variant of Excalibur — same kit fantasy with Prime stats and polarities. Excalibur epitomizes the warrior spirit. Built around Slash Dash, Radial Blind, Radial Javelin.

Passive

Excalibur Prime deals a percentage increased damage and attacks a percentage faster when wielding swords.

When to Pick

  • You want Excalibur’s kit with Prime polarities / stats.
  • You want a summoner / companion toolkit and Excalibur’s fantasy matches the mission.
  • Your squad is missing what Excalibur brings — especially Slash Dash.

Kit Overview

  • Ability kit matches Excalibur — open the base ability pages for deep dives.
  • Slash Dash (Ability 1): Slash and dash through enemies alongside a radial specter.
  • Radial Blind (Ability 2): Emit a bright flash of light, blinding all nearby enemies.
  • Radial Javelin (Ability 3): Radial javelins impale nearby enemies, inflicting Slash Status.

    Radial Blind

    Emit a bright flash of light, blinding all nearby enemies.

  2. 2
    Radial Javelin

  3. 3
    Slash Dash

    Slash and dash through enemies alongside a radial specter.

  4. 4
    Exalted Blade

    Summon a sword of pure light and immense power.

Helminth / Subsume

  • Slash Dash is often the Helminth sacrifice if your build never needs Ability 1 and you’d rather import a strip, buff, or survival tool.
  • Keep Radial Blind and later abilities when they define Excalibur’s identity.
  • Never subsume the ability that enables the rest of the kit’s energy or survival loop.

Mod Scaling

Strength

Raises damage and effect potency across Excalibur’s Strength-scaling abilities.

Duration

Extends channeled / timed effects — often comfort on Excalibur if the kit leans on buffs or zones.

Range

Helps radius / targeting tools. Dump it if Excalibur is mostly self-buff or exalted weapons.

Efficiency

Keeps ability uptime comfortable, especially on longer Steel Path missions.

Priority

Match the priority to your main ability — Strength or Duration first for most kits, then Efficiency, then Range.

Mission Usefulness

Mission / ContextRatingWhy
Steel Path Survival / Defense / DisruptionExcellentBring Excalibur Prime when you want Exalted Blade carrying Survival / Defense / Disruption tiles without a full strip team. Summon a sword of pure light and immense power. Excalibur epitomizes the warrior spirit.
Mobile Defense / ExcavationStrongExcalibur Prime can hold Mobile Defense / Excavation without sweating every spawn, mainly via Slash Dash. Slash and dash through enemies alongside a radial specter. Excalibur epitomizes the warrior spirit.
Exterminate / Capture Speed RunsExcellentIf the goal is extract ASAP, cast Slash Dash on Excalibur Prime and ignore slow channeled setups. Slash and dash through enemies alongside a radial specter. Excalibur epitomizes the warrior spirit.
Spy / Rescue / NightmareWeakLoud kit. Leave Spy / Rescue to invis or silence frames; Slash Dash doesn’t make Excalibur Prime quiet. Slash and dash through enemies alongside a radial specter. Excalibur epitomizes the warrior spirit.
Open World / BountiesStrongStrong on packed bounty camps; Excalibur Prime still leans on Operator / Archwing for the empty travel stretches while Slash Dash handles fights. Slash and dash through enemies alongside a radial specter. Excalibur epitomizes the warrior spirit.
Long-Range Gunplay / Eidolon-Style ContentWeakExcalibur Prime wants pack clear or finishers, not pure long-range; Exalted Blade won’t save an Eidolon-style loadout. Summon a sword of pure light and immense power. Excalibur epitomizes the warrior spirit.
