  • Two base-Strength casts fully strip armor; shields diminish per hit on current max.
  • 200% Strength (or ~164% with Corrosive Projection) one-shots full armor strip.
  • Shove Event Horizon away from Orion to drag the blob across the tile.
  • Cheap 15-energy strip — weave it between guns while Orion is controlled.

Mod Scaling

Strength

Strength scales Gravitic Slash’s damage and key effect values — mandatory on nuke/strip/heal paths.

Duration

Duration matters on Gravitic Slash when the ability is timed (buffs, zones, black hole, motes).

Range

Range grows Gravitic Slash’s hit radius, vacuum, or explosion — high priority for tile clear.

Efficiency

Base cost 15 energy — Efficiency plus swap passive keeps dual casting cheap.

Priority

Strength and Range first for clear; Duration for zones/shell/motes; Efficiency for long missions.

Mission Use Cases

MissionHow to Use It
Steel Path Survival / Defense / DisruptionTest whether Gravitic Slash still clears or enables clear when enemies are dense and overlevelled.
Mobile Defense / ExcavationUse Gravitic Slash to control or delete the swarm on the objective, then reposition.
Exterminate / Capture Speed RunsCast Gravitic Slash only when it saves time — skip it on empty tiles.
Spy / Rescue / Quiet RoutesIf Gravitic Slash 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 — Gravitic Slash is tuned for Sirius & Orion’s loop — don’t judge it as a standalone subsume without the rest of the kit.
