CODEX

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 7,500 Credits 7,500.

Characteristics

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

Advantages:

• High damage on primary fire – effective against armor.
• High damage on alt-fire – effective against shields.
• Primary Fire charges and shoots thin beams.
  • Beams are hitscan and does not have projectile travel time, despite the animation.
  • Very high critical chance and critical multiplier.
  • Innate 1.5 meter Punch Through.
• Very fast charge speed.
  • Vaporizes enemies on kill, making it good for stealth when silenced.
• Alternate Fire throws the Ferrox, creating a field dealing damage and pulls enemies within 10 meters toward the Ferrox every 2 seconds.
  • Tied with  Miter and  Daikyu for the highest status chance of all primary weapons.
    • Can reach 100% status chance with two of the following:  Thermite Rounds,  Rime Rounds,  High Voltage, and  Malignant Force.
  • Reloads 33% of the clip while deployed.
• Very ammo efficient.
• Innate and polarities.

Disadvantages:

• Primary Fire:
  • Low damage – less effective against shields.
  • Low status chance.
  • Shoots thin lasers, requiring 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.
• Alternate Fire:
  • Low damage – less effective against armor.
  • Extremely low critical chance.
  • Once 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 10 seconds if quick thrown or 30 seconds if charged thrown.
  • Thrown spear has travel time.

Notes

• 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 enemies within 10 meters, dealing 150 damage every 2 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.

Tips

• 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, will be applied last if there are two or more, other elements modded for, unless an 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 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, thrown secondaries with  Concealed Explosives, and weapons that chain between targets like the  Atomos are good choices when using the Ferrox in this manner.
  • This will also assist squadmates with launcher-type primaries such as  Zarr and  Tonkor, as well as any weaponry with procs.

Trivia

• 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".
