The Strun is a standard shotgun. Reliable, versatile and deadly.

The Strun is a powerful shotgun that is the successor to the Strun MK1-Strun. The Strun bears good damage per shot and decent status chance, capable of killing most light enemies in a single shot.

This weapon can be sold for Credits64 7,500.

Characteristics[]

  • This weapon deals primarily DmgImpactSmall64 Impact damage.
  • Innate multishot of 12 pellets.

    • Reloading has a 0.5 second delay to start and a 0.25 second delay to end.
    • Since the weapon reloads one shell at a time, mods that increase magazine size also increases total reload speed.

Acquisition[]

A built Strun can be purchased from the Market for Credits64 25,000.

Notes[]

  • Reload time is 0.75s + 0.5s per round, coming to 3.75 total seconds to reload a completely empty mag.
    • This time will further increase if magazine mods such as Mod TT 20px Ammo Stock are used.
  • Compared to the Boar Boar, the Strun has a tighter pellet cone and a much more efficient ammunition economy. The Hek Hek has an even smaller base magazine size than the Strun, but bears an even tighter pellet cone and a more efficient ammunition economy. The Strun could be considered the middle ground of the three.
  • Before Update 12.0 (2014-02-05), the weapon's price in the market was Credits64 75,000.

Incarnon Genesis[]

Evolution[]

  • Installing the Strun Incarnon Genesis requires 20 PathosClamp Pathos Clamps, 60 RuneMarrow Rune Marrow, and 60 TasomaExtract Tasoma Extract.
  • When installed, the first Evolution tier is unlocked. The following Evolution tiers, their requirements for unlocking them, and their related perks, are shown below;

Evolution I[]

  • Weakpoint hits charge Incarnon Transmutation; Alt Fire transmutes. Switching back will expend any remaining charges.
  • Fire staggering explosive projectiles.
  • Mode switching is not instantaneous and has an animation equal to the weapon's reload speed.
  • Incarnon Form is activated by filling the Incarnon Transmutation gauge that appears under the reticule by achieving weakpoint hits and then pressing the Alternate Fire button. 40 weakpoints will completely fill the gauge. A full gauge is not required to activate Incarnon Form.
    • Charges do not generate on the backpacks of most MOA variants, or vulnerability spots generated by Sonar130xWhite Sonar or Mod TT 20px Detect Vulnerability in places other than actual weakpoints.
    • Weakpoints on corpses or Invulnerable targets do not build charges.
    • Individual Multishot bullets can build charges.
  • Instead of drawing ammunition from its reserves, the Strun's Incarnon Form uses a separate "magazine" with each charge producing 1 round to a maximum of 40. Once all ammunition is expended, the Strun reverts to its normal form.
    • Incarnon Form's magazine is not affected by mods.
    • Incarnon Form is not affected by Ammo Efficiency (such as EnergizedMunitions130xWhite Energized Munitions).
    • Charges and Incarnon Form persists through all activities, such as holstering, bleedout, or being disarmed. However, charges and Incarnon Form are removed upon death.
  • Swapping to and from Incarnon Form will fully reload the normal form's magazine.

Tips[]

Trivia[]

  • The Strun appears to use a tubular magazine, presumably the cylindrical protrusion near the rear above the stock - the Warframe will push this section while reloading.
    • Assuming the Warframe is adding shells into this tube, or replacing it, it would imply that the shells used by Strun are extremely small, which is puzzling given the enormous choke.
  • When it was originally released, the Strun was magazine-fed, with the small knob on top of the weapon being its magazine. This was changed into the shell-feed system currently in use.
  • The regular Grineer Trooper previously used this weapon prior to Update 11.0 (2013-11-20), and currently wield Sobek Sobeks.
  • Corrupted Crewmen used to wield a Strun in Void missions, except their version fired a burst of yellow energy pellets instead of bullets.
  • The Strun shares many similarities to the Boar.
  • The Strun received a PBR (Physically Based Rendering) update in Update 16.7 (2015-06-04).

Patch History[]

Hotfix 37.0.1 (2024-10-02)

  • Fixed the Strun clipping into Koumei when holstered.

Update 32.0 (2022-09-07)

Ammo Changes

We understand the power fantasy of these weapons is very popular for some, so our first approach was to keep them powerful, but limit how often they can be used by making changes to ammo pick-up.

Ammo Pickup Overrides
The following weapons now have ammo pickup overrides, meaning they gain less from picking up ammo. This mostly applies to AoE weapons, in hopes that players will become more deliberate with their aim to make the most of their Ammo pools. The following lists the specific ammo pick up overrides per weapon category.

Primary Weapon Ammo Pick Up Overrides

15 Ammo per Pick Up:

  • Strun

Update 30.9 (2021-11-11)

  • Fixed reloading an extra bullet into the Strun if you fired 5 or more shots before the reload.

Update 27.2 (2020-03-05)

Greater than 100% Status having meaning:

Shotguns have a unique Role here based on a very patch-work history with how they interact with Status Chance. A Shotgun that shoots 99% Status Chance would give you 35% (roughly) status per pellet. 100% Status Gives you 100% Status per pellet. This huge jump in performance happens with just a 1% gain - why? Well, to answer that we have to look at our choice to make what the UI conveys reality. It would feel broken to shoot a Shotgun with 100% Status and not see a perfect spread of Effects. In reality, to make Status consistent we have to treat Shotguns as a special case.

Shotguns as a special case means we have buffed the Status Chance of all Shotguns by x3 or greater. The UI now behaves to show the reality that you are determining Status Chance per pellet.

  • (Undocumented) Status chance per projectile increased from 1.6666666666667% to 5%.
