Munitions Vortex is a Plexus Battle Defensive mod. It deploys a bubble that vacuums all enemy projectiles and reflects damage to enemies that pass through it, before exploding upon expiration or manual deactivation (default 1 ) and dealing all accumulated damage over a radius.

  • Projectile crawls forward in a straight line from the Railjack for a very short distance (~50m) before stopping; this travel time counts against its maximum duration. As such, it is recommended to close the gap as much as possible before activation.
  • Though powerful when charged, its effect has a small effective radius. As such, it is best used when combined with Mod TT 20px.png Tether or Mod TT 20px.png Void Hole, allowing enemies to be grouped, immobilized, and struck by any orbiting projectiles before detonation.
  • The Vortex will pull on the missiles launched by abilities such as Void Hole or Mod TT 20px.png Shatter Burst, but does not act as a surface that would cause them to immediately detonate. As such, the Vortex can be used as a grouping tool for multiple missile-based effects, stacking them in one spot.
  • The Vortex can pull in incoming enemy fire, allowing it to be used as a shield against enemy projectiles.
  • Can be an effective response to incoming Ramsleds, as the projectile can be placed as a trap, charged by fire, and detonated when pods are close to the Railjack.
