The '''Amprex''' is a [[Corpus]] rifle that is unlockable through the [[Research#Energy Lab|Energy Lab]] in the [[Dojo]] after researching the [[Dera]]. The Amprex can easily destroy large crowds of enemies by firing multiple {{Icon|Proc|Electricity|text}} arcs that can chain between units.

Revision as of 11:09, 5 February 2020

The Amprex rifle fires a continuous beam of high voltage electricity that arcs among nearby enemies. This weapon excels at crowd control.

The Amprex is a Corpus beam rifle that fires a continuous stream of Script error: The function "Proc" does not exist. arcs that can chain between units, making it a devastating crowd control weapon. It can be researched from the Energy Lab in the dojo.

This weapon can be sold for Credits64 7,500.

Characteristics

This weapon deals Script error: The function "Proc" does not exist. damage.

Advantages:

  • Innate Script error: The function "Proc" does not exist. damage – effective against Machinery and Robotics.
  • Second highest critical chance of all continuous and automatic primaries, behind Synapse Synapse.
  • Above average critical multiplier.
  • High status chance.
  • Mod TT 20px Heavy Caliber's accuracy penalty is minimal on this weapon.
  • Beam can chain up to 3 nearby enemies from the initial target.
    • Enemy corpses will still allow the beam to connect to nearby enemies.
  • Consumes 0.5 ammo per tick of damage.

Disadvantages:

  • Innate Script error: The function "Proc" does not exist. damage – less effective against Alloy Armor.
    • Damage cannot be increased with Script error: The function "Proc" does not exist., Script error: The function "Proc" does not exist. or Script error: The function "Proc" does not exist. mods.
  • Damage ramps up from 25% to 100% over 0.6 seconds when firing. After firing stops for 0.8 seconds, the damage decays back to 25% over 2 seconds.
  • Slow reload speed.
  • Main beam has a limited range of 18 meters.
  • Chain beam has a limited range of 10 meters.

Notes

  • Resource-heavy to craft, requiring Script error: The function "Resource" does not exist. 8 Fieldron and Script error: The function "Resource" does not exist. 3 Argon Crystals, as well as Script error: The function "Resource" does not exist. 9000 Ferrite.
    • However, the Amprex is one of the few Clan Tech weapons that does not require Script error: The function "Resource" does not exist. to craft, along with Anku Anku, DualRaza Dual Raza, NamiSkyla Nami Skyla, Lacera Lacera, Serro Serro, and Sydon Sydon.
  • When fired at an enemy, the beam will chain to the closest living enemy within 7 meters of the initial target. From there it will chain again, up to a maximum of 3 chains in total. A chain will do 0.75n(n+1)/2 times the main beam's damage, where n is the chain number. Any enemy caught in the width of the beam will also be damaged.
    • Headshotting the original target does not affect the chain damage.
    • The beam will not chain to a Nullifier through its shield should it connect with a target outside or partially enclosed by it.
    • The beam can also continue to chain to enemies even if targeting a dead enemy or an enemy who is dead but in a dying animation.
    • Additional electrical arcs are also emitted, striking randomly around the player. However, these stray arcs are purely visual in effect.
  • Compared to the Synapse Synapse, the Amprex deals more damage and it continuously arcs to other enemies, making it more effective against crowds. Use the Synapse for single targets and the Amprex for crowd control.
    • The fire rate of Amprex is the same as Synapse, and it deals slightly more damage, however it has a 2.6s reload speed, nearly double the 1.5s reload speed of the Synapse.

Tips

  • This weapon's high critical chance and damage make it ideal for critical focused builds using Mod TT 20px Point Strike and Mod TT 20px Vital Sense.
  • The Amprex's high fire rate and its low base damage make it highly ammo inefficient, consuming ammo at an alarming rate. It is recommended to use Mod TT 20px Rifle Ammo Mutation, Carrier's Mod TT 20px Ammo Case, or Mod TT 20px Rifle Scavenger to ensure a steady supply of ammo. Alternatively, bring Squad Ammo Restores to help replenish lost ammo.
  • Alloy Armor is highly resistant to electricity damage. To counteract this, consider pairing it with Script error: The function "Proc" does not exist. or Script error: The function "Proc" does not exist. damage to respectively create Script error: The function "Proc" does not exist. or Script error: The function "Proc" does not exist. damage.
  • Mod TT 20px Critical Delay can be used to reduce ammo consumption, increase time between reloads, and increase damage per hit, but at a cost to the weapon's DPS.
  • Although it is preferred to mod the weapon to other damage types, base Script error: The function "Proc" does not exist. damage paired with its high status chance makes for a good stunning weapon among groups, and the added damage through electrical procs that chain to other enemies. Infested have no weakness or resistance to electrical damage, making the base electrical damage work well for that faction. Forma is often required to change the damage type to match the amount of damage done by pure electrical damage, however.
  • Mod TT 20px Metal Auger will allow the Amprex to hit multiple targets with its main beam. Each target hit with the main beam causes a separate set of chained damage to nearby enemies, causing this weapon to deal significantly more damage the more enemies you are able to hit. Hitting multiple enemies at one time may be difficult in practice due to the Amprex's short range. On the other hand, this mechanic has good synergy with abilities like Vauban's Vortex, which allows the main beam to easily penetrate multiple grouped targets.
  • Using with MirageIcon272 Mirage gives you two more beams that also chain to other targets, providing much more crowd control.
  • Decreasing the accuracy of the Amprex with a mod like Heavy Caliber will not only increase the Amprex's damage but works well for large groups of enemies as it increases the spread of the weapons Fire.
  • Firing at a corpse also damages nearby enemies.

Trivia

  • After the clan obtains the Energy Lab, it will take exactly 12 days to research this weapon.
  • The Amprex's name is a portmanteau of the words Ampere (the base unit of the International System of Units used to quantify electric current) and the word Rex, which is the Latin word for king.
    • The word ampere itself is named after a French mathematician and physicist, André-Marie Ampère, who's also considered to be one of the fathers of classical electromagnetism, most commonly known for Ampère's Circuital Law.
    • Like the FluxRifle Flux Rifle and Detron Detron, Amprex does not conform to the common Corpus weapon name scheme; two syllables ending in 'a'.
  • The weapon shares its similarities on its battery components with Tetra Tetra.
  • This is the third Primary weapon that deals purely Script error: The function "Proc" does not exist. damage, after the Lanka Lanka, and Synapse Synapse.
  • This is the second clan weapon that does not need a Forma in its construction.
  • Hatches on the side of the Amprex slowly open up during firing, spreading vanes underneath. This animation is a visual indicator of the weapon's magazine capacity, with the vanes spreading out more the closer the magazine is to empty. The hatch closes upon reloading.
  • This is the first weapon in Energy Lab whose duplication costs 50,000 credits.
  • After Update 15.13 (2015-02-05), the chained beams were changed to be affected by Mod TT 20px Sinister Reach as well. As of Update 22.14 (2018-03-01), this is no longer the case.

Patch History

Update 22.14 (2018-03-01)

  • Fixed Beam weapons not being able to damage enemies (alive but in a ragdolled state) when being affected by certain ‘crowd control’ Abilities.
  • Damage now ramps up over 0.6 seconds and after moving off target there is a delay of 0.8 seconds before it starts to decay over 2 seconds.
  • All Beam weapons now start their Damage ramp up at 20% (instead of 10%).
  • The Multishot chance should now apply more consistently with Beam weapons.
  • Weapon Range Mods (like Sinister Reach) no longer affect the distance of chains for chainable Beam weapons (like the Amprex). Main Beam distance is still affected by them.
  • Fixed Beam weapons continuously firing when quick Meleeing.
