CODEX

Dominate rivals with this pistol’s lightning fast rail-slugs. Head-shots speed up reload.

The Tenet Spirex is a unique Tenet pistol railgun that fires  Heat explosive projectiles with extreme Projectile Speed. Successfully achieving a headshot with this weapon temporarily grants it faster reload speed.

Characteristics

This weapon primarily deals  Heat damage.

Advantages:

• Innate  Heat damage – effective against Cloned Flesh, Infested, and Infested Flesh.
• Very high critical chance.
• High critical multiplier.
• Extremely high status chance.
• Shots have a guaranteed  Impact proc.
• Shots explode in a 2 meter radius upon impact with a surface or enemy.
  • Initial hit and explosion apply status separately.
  • Explosion does not need direct line of sight to deal damage and will penetrate walls.
  • Can benefit from  Fulmination ( Primed).
• Extremely fast Projectile Speed.
• Landing a successful headshot grants the "Bullseye Reload" buff, increasing reload speed by 25% and can stack up to 2 times to a total of 50%. The buff lasts 4 seconds and can be refreshed on subsequent headshots.
• Innate two polarities.
• Polarizing the weapon increases its max rank by 2, capping at rank 40 after 5 polarizations, granting the weapon additional mod capacity.
• Comes with an additional bonus  Impact,  Heat,  Cold,  Electricity,  Toxin,  Magnetic, or  Radiation damage, based on the Sister's progenitor Warframe, which increases the listed base damage of the weapon by 25%-60%.

Disadvantages:

• Innate  Heat damage – less effective against Proto Shields.
• Slow fire rate.
• Slow base reload speed.
• Moderate recoil.
• Projectiles have travel time.
• Explosion inflicts self-stagger.
• Explosion has linear damage falloff from 100% to 80% from central impact.
• Low accuracy.

Acquisition

Tenet Spirex is obtained by vanquishing a Sister who generated with one equipped. After the Sister is vanquished it will be in the player's Foundry ready to claim.

While the weapon itself is not tradeable, a converted Sister generated with the weapon can be traded to another player. The trade is performed inside a Clan Dojo's Crimson Branch room, and the recipient must not have any active Lich or Sister. Once traded, the recipient must fight and vanquish the Sister to claim their weapon.

Notes

• Bullseye Reload buff reduces reload time to 1.9 seconds at one stack and 1.6 seconds at two stacks, assuming no other reload speed mods are equipped.
  • The buff triggers only on headshots, and not other weakspots, such as the backpacks of most MOA variants. Similarly, shooting weakspots generated by either  Sonar or  Detect Vulnerability in places other than heads will have no effect either.
• Because of its projectiles exploding on impact, the Tenet Spirex can be considered the Corpus's answer to the  Kuva Seer, which also has exploding projectiles.

• As with all Kuva and Tenet weapons, the player does not have to meet the Mastery Rank displayed to obtain this weapon. It can simply be claimed from the foundry after the Kuva Lich or Sister carrying it has been vanquished.
• The weapon will have a prefix of the name of the Lich/Sister it was acquired from (e.g. Odizrigg Agekk Kuva Kohm).
• The weapon's max rank caps at 40 after 5 polarizations (max rank increases by 2 per Forma added).
  • Additional polarizations can be added when the weapon reaches its new max rank at that polarization level.
  • Each additional rank also gives 100 Mastery Rank experience, giving 4,000 points in total at level 40.
  • Mod capacity scales with the additional ranks, and can reach a total of 80 at rank 40 with an Orokin Catalyst installed.
    • Without an Orokin Catalyst, the max is 40. Combined with the five polarized mod slots required to reach that point, an Orokin Catalyst might not be required to finish modding the weapon.
    • After polarizing a weapon, any additional mod capacity above 30 (60 with an Orokin Catalyst) will not take effect until the weapon's rank reaches 31 and above.
      • Legendary Mastery Rank increases the minimum mod capacity for such weapons, without the weapon needing to be rank 31 and above. For example, Legendary 1 increases the minimum capacity to 31 (62 with an Orokin Catalyst).
• Comes with an additional damage stat, dependent on the Warframe that summoned the Lich/Sister.
  • This damage stat ranges between 25%-60%, and is randomly generated by the Lich/Sister. It can be brought up to its maximum value with Valence Fusion using another copy of the weapon.
  • This bonus stat is considered a base damage type that is added after all elemental mods.

• • If the weapon innately has a primary element type ( Heat,  Cold,  Electricity,  Toxin) AND has a different primary element as its bonus stat, the elements on the weapon will combine in a unique way: Whichever of the two primary elements comes first in this element order -  Heat >  Cold >  Electricity >  Toxin, or "HCET" for short - will be placed second to last in the element combine order, while the other primary element will be placed last in the combine order. This order can be subsequently shifted based on the order of the equipped mods.
  • For example, if the weapon innately has  Cold, using an  Electricity progenitor Warframe to add base  Electricity damage to the weapon will change the weapon's base element to  Magnetic.
    • Because  Cold comes before  Electricity in the HCET element order,  Cold will be placed second to last in the element combine order, and  Electricity will be placed last.
    • If the weapon is then modded with only  Heat, the elements will be arranged in the order  Heat,  Cold,  Electricity, resulting in the weapon having  Blast +  Electricity. If the weapon is instead modded with only  Toxin, the elements will be arranged in the order  Toxin,  Cold,  Electricity, which will create  Viral +  Electricity.
    • If modded with  Electricity and  Heat, the  Electricity will be moved earlier in the combine order due to now being a modded element, so the new combine order will be  Electricity,  Heat,  Cold, resulting in  Radiation +  Cold. If modded with  Heat and  Toxin, the combine order will be  Heat,  Toxin,  Cold,  Electricity, resulting in  Gas +  Magnetic.

*Note that the Primed or Umbra version of a Warframe share the same element

Tips

• Because of both its low fire rate and guaranteed  Impact proc on direct hits, the Tenet Spirex is a perfect candidate for  Hemorrhage to nearly guarantee  Slash procs on every hit.
  • An  Impact Damage bonus may also be considered as it also allows the projectile's explosions to deal Impact damage, inflicting Slash procs in a small area.

Trivia

• An enemy exclusive non-Tenet variant of the Spirex can be seen used by Juno Crewmen.
