- The MK-1 Strun is a slightly weaker version of the standard Strun, with less overall damage and a slightly slower rate of fire.
Incarnon Genesis[]
- Upon completion of The Duviri Paradox and Angels of the Zariman, and unlocking The Steel Path, players can earn Strun Incarnon Genesis from The Circuit's Steel Path to place on their Strun with the help of Cavalero in the Chrysalith. This Incarnon Genesis form grants it evolutions to a transformation and newfound strength.
Evolution[]
This section is transcluded from Strun Incarnon Genesis § Evolutions. To change it, please edit the transcluded page.
- Installing the Strun Incarnon Genesis requires 20 Pathos Clamps, 60 Rune Marrow, and 60 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;
- Each challenge additionally grants 5,000 affinity to the weapon, affected by Affinity Boosters.
Evolution I[]
- Headshots charge Incarnon Transmutation; Alt Fire transmutes. Switching back will expend any remaining charges.
- Fire staggering explosive projectiles.
- Incarnon Form now inflicts a 4 meter area of effect that deals primarily Blast damage, with much higher Critical Chance, Critical Multiplier, and Status Chance. However, it loses shotgun multishot mechanics and has a base multishot of 1, the Fire Rate is reduced, has much lower base damage, and the explosion possesses Damage Falloff from 100% to 80% from central impact.
- Incarnon Form now inflicts a 4 meter area of effect that deals primarily
- 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 headshots and then pressing the Alternate Fire button. 20 headshots will completely fill the gauge. A full gauge is not required to activate Incarnon Form.
- Charges generate 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.
- Headshots on corpses do not build charges.
- Individual Multishot bullets can build charges.
- Charges generate only on headshots, and not other weakspots, such as the backpacks of most MOA variants. Similarly, shooting weakspots generated by either
- Instead of drawing ammunition from its reserves, the Strun's Incarnon Form uses a separate "magazine" with each charge producing 2 rounds 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 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[]
- Using the Shotgun Ammo Mutation mod can help regain ammo when needed, although not as often as the full auto shotguns.
- Weapon's spread cone can be shrunk by zooming in.
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 quite puzzling given the enormous size of the barrel diffuser.
- The regular Grineer Trooper used to use this weapon prior to Update 11.0 (2013-11-20). They now wield a Sobek.
- The Strun is most likely a Tenno weapon, despite its augmentation the Strun Wraith, a Grineer-focused customization. The Strun bears a faint Tenno marking on its stock as proof.

Patch History[]
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:
- MK1-Strun
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 2% to 6%.
Update 17.0 (2015-07-31)
Several changes have been made to shotgun weapons across the board -- resulting in a list of changes similar from weapon to weapon. The following list of changes apply to all Primary Shotguns with exception to the Phage:
- Increased damage across all shotguns.
- Damage after projectile falloff has been increased for all shotguns.
- Some shotguns have been given improvements to reload speed.
- Some shotguns have received improvements to their projectile speed.
- Death at close to mid range will now toss enemies into a forceful ragdoll.
- (Undocumented) Strun series changed from magazine-based reload to shell-by-shell reload.
