The Tenet Spirex is the Tenet variant of the Spirex railgun pistol 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 deals innate
Heat damage. - 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.
- 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).
- Shots have a guaranteed Impact proc.
- 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%.
- Valence Fusion can optionally change the resulting output damage type, and can upgrade the bonus increase (up to 60%).
- Polarizing the weapon increases its max rank by 2, capping at rank 40 after 5 polarizations, granting the weapon additional mod capacity.

Acquisition[]
This section is transcluded from Lich System/Weapons § Tenet Acquisition. To change it, please edit the transcluded page.
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.

Kuva/Tenet Notes[]
- For weapons obtained from vanquishing the Kuva Lich or Sister:
- 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 Lich/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. a Kuva Kohm might be called "Odizrigg Agekk Kuva Kohm").
- Refraining from Mercy killing an Adversary candidate will remove their weapon from the pool of potential Adversary weapons until each has been refused, but only if the mission is completed. Weapons rejected from aborted missions will remain in the current cycle.
- For weapons obtained from Ergo Glast's shop:
- The player must meet the Mastery Rank displayed to obtain this weapon, as it is claimed from an NPC shop rather than the foundry.
- 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 for some beginner-friendly builds as they typically use less mod capacity.
- 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.
- For Lich/Sister-obtained weapons this is dependent on the Warframe that summoned the Lich/Sister.
- For Ergo Glast shop a random bonus stat will be offered for each weapon and changed every 4 days (96 hours).
- This damage stat randomly ranges between 25%-60%. It can be upgraded up to its maximum value with Valence Fusion using another copy of the weapon.
- This bonus stat is considered a base damage type and will be applied after all elemental mods for the purposes of elemental combinations.

- Weapons with an innate primary element and a different primary element provided by the progenitor both behave as innate elements and combine with each other. They will also recombine with modded elements in the following order:
- Mod slot 1 → Mod slot 2 → ... → Mod slot 8 → Innate Heat → Innate Cold → Innate Electricity → Innate Toxin
- Mod slot 1 → Mod slot 2 → ... → Mod slot 8 → Innate

Known Bugs[]
- Galvanized Shot is multiplicative to base damage sources on direct hits.
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.
- An
Trivia[]
- An enemy exclusive non-Tenet variant of the Spirex can be seen used by Juno Crewmen.
- According to the concept art, the Spirex was based on the Noisy Cricket from the MIB series.

Patch History[]
Update 33.0 (2023-04-26)
- Fixed the Energizing Shot Mod working on the Tenet Spirex’ AOE.
- As indicated in the mod’s description, it is intended not to work on AOE.
Update 32.0 (2022-09-07)
- Headshot Damage Changes
During playtesting, the ammo changes alone weren’t enough to significantly change things for AoE weapons. So instead of tightening these values to be overly restrictive, we chose to address other factors that make these weapons so strong, such as headshot damage.
Our approach here is two-fold, to reduce the impact of headshots for AOE weapons, but to also make precision headshots pack a larger punch overall.
- Radial damage no longer gains extra headshot damage or triggers headshot conditions.
- This is primarily targeted at the Ignis Wraith - as a “flamethrower” weapon, it’s hard to imagine a blanket of elements being precise enough to target weak points specifically. Explosive projectiles themselves can still land headshots, so there is still a reason to aim with most weapons for maximum damage.
Update 30.5 (2021-07-06)
- Introduced.
