Discharge a rail of ionized death or throw the Ferrox like a spear and create a localized field of attraction no enemy can escape from.

The Ferrox is a Corpus Speargun introduced and wielded by Index broker Derim Zahn. The primary fire features a charged shot that deals high damage, complimented by its high critical stats. Its Alternate Fire tosses the Ferrox as far as 50 meters, creating an electric field where it lands and pulls enemies towards it. It is available for research in the Energy Lab of the Clan Dojo.

This weapon can be sold for Credits647,500.

CharacteristicsEdit

This weapon deals primarily Puncture b Puncture damage on its primary fire and Impact b Impact damage on its alt-fire.

Advantages:

  • High Puncture b Puncture damage on primary fire - effective against armor.
  • High Impact b Impact damage on alt-fire - effective against shields.
  • Primary fire lasers are hitscan.
  • Primary fire has an innate 1.5 meter Punch Through.
  • Alt-fire throws the Ferrox that creates a field that pulls in enemies.
    • Enemies will be dealt 150 Electricity b Electricity when trapped in said field.
  • Primary fire has very high critical chance.
  • Primary fire has high critical multiplier.
  • Alt-fire has very high status chance.
  • Very ammo efficient.
  • Very fast charge speed.
  • Comes with a Madurai Pol and Vazarin Pol slot.
  • Killed enemies are vaporized, making it good for stealth when silenced.

Disadvantages:

  • Low Impact b Impact damage on primary fire - less effective against shields.
  • Low Puncture b Puncture damage on alt-fire - less effective against armor.
  • Primary fire shoots thin lasers; requires precise aiming.
  • Cannot fire with a partial charge.
  • The weapon fires as soon as it has reached a full charge which can lead to premature firing.
  • Once the Ferrox is thrown, the player will not be able to use it until it is either picked up or when it returns to the player's hands after 20 seconds.
  • Primary fire has low status chance.
  • Alt-fire has slow projectile speed and ticks slowly.
  • Alt-fire has extremely low critical chance.

NotesEdit

  • The Ferrox' alternate fire throws the weapon itself at the target, and upon landing on a surface arcs of electricity will emit from the Ferrox and chain to any nearby enemies, dealing 150 Electricity b Electricity damage every 5 seconds with a moderate chance to proc. Enemies under this effect will also be passively dragged towards the Ferrox.
    • The damage's tick rate is affected by fire rate mods.
    • Multishot neither increases the tick's damage nor rate.
    • Currently, reaching 100% status on the alt-fire does not guarantee procs; it is more in line with the normal attack's status chance.
  • The Ferrox automatically teleports back to the player 20 seconds after being thrown, or until the player manually picks the Ferrox back up again.
    • Throwing the weapon does not consume ammo.
  • The Ferrox' alt-fire has a maximum throwing range of ~50m (though it may be displayed as slightly less due to the forward movement of the player when throwing the weapon).
    • The arc Ferrox will take when thrown is affected by both the angle of the throw as well as how much the throw was charged.
    • Throwing distance can be increased with flight speed modifiers (e.g. Terminal Velocity and Zephyr's Jet Stream Augment).
    • Unlike the Javlok, the Ferrox' alt-fire will not damage its user when thrown too close.
  • If the Ferrox is silenced using Hush, Hushed Invisibility, or Banshee's passive ability, its alt-fire will not alert enemies when dragging and dealing damage to them.
  • Enemies killed by the primary or damage from the secondary attack will vaporize, similar to channeled kills by melee weapons. This makes it very suitable for stealth, as long as the weapon is silenced or Hushed Invisibility is used.
    • This only occurs if the enemy was the last in the line of a primary shot. If a Ferrox shot kills multiple enemies at once due to punchthrough, not all targets will be vaporized.
  • It is not recommended to install Heavy Caliber as the accuracy will greatly deviate leading to inaccurate shots even with the secondary fire.

TipsEdit

  • This weapon's high critical chance and critical multiplier makes critical builds using Point Strike and Vital Sense very good options.
  • When applying additional elements to the Ferrox, its alt-fire will proc them periodically; as with other weapons with an elemental base, Electricity b Electricity will be applied last if there are two or more, other elements modded for, unless an Electricity b Electricity mod is included in the order.
  • Tactical Reload will still have an effect while the spear is out after the alt-fire is used, so it's possible to do seamless reloads this way.
  • The Ferrox' alt-fire is very useful as a crowd control tool in Survival missions, as its tethering arcs may stun enemies with Electricity b Electricity procs and also pull them together in a close bunch.
    • It is further amplified on corridors where enemies pass through frequently.
    • Grenade-type secondary weapons such as Angstrum and Kulstar or thrown secondaries with Concealed Explosives are good choices when using the Ferrox in this manner.
    • This will also assist squadmates with launcher-type primaries such as Zarr and Tonkor.

TriviaEdit

  • The bodies of enemies killed by this weapon disintegrate in a manner similar to channeled Melee kills.
  • Has the same aesthetic as the Ohma tonfas and Quaro armor set.
  • The name Ferrox seems to be a mix of the Latin words Ferox, meaning "savage" or "fierce", and Ferrum, meaning "iron".
