Bolts from this Corpus bow deliver a one-two punch of an icy pulse, followed by a conventional explosion. Excess ammo picked up for other weapons will be converted into charges for the Lenz.

Warning, safety-protocols do not exist on this prototype.

The Lenz is a IconCorpusB.svg Corpus bow with several unique mechanics. It has a built-in ammo mutation to compensate for its rather small ammo pool, and it fires special bolts that inflict weak Cold DamageDmgColdSmall64.png Cold procs within a eight-meter radius before exploding and dealing a large amount of Blast DamageDmgBlastSmall64.png Blast damage within six-meters.


This weapon deals primarily Blast DamageDmgBlastSmall64.png Blast damage.




The Lenz's blueprint can be researched from the Energy Lab in the dojo.

  • Cannot use the bow-exclusive ThunderboltMod TT 20px.png Thunderbolt mod.
  • Having an innate arrow ammo mutation effect, the Arrow MutationMod TT 20px.png Arrow Mutation mod is not required with this weapon despite its tiny ammo reserve. However, as the innate mutation effect only restores one unit of ammunition per ammo pickup, the use of this mod is left to the user's discretion.
    • The weapon is currently able to equip both Arrow Mutation and Sniper Ammo MutationMod TT 20px.png Sniper Ammo Mutation mods, with stacking effectiveness. The conversion is still limited by the maximum ammo of the weapon however.
  • There are actually three sources of damage with the weapon. The arrow itself will deal Impact DamageDmgImpactSmall64.png Impact, then a large Cold DamageDmgColdSmall64.png Cold proc will occur when the arrow hits an enemy or surface, before exploding with Blast DamageDmgBlastSmall64.png Blast damage. This is why if the user adds a single elemental like Electricity DamageDmgElectricitySmall64.png Electricity, the weapon will show both Magnetic DamageDmgMagneticSmall64.png Magnetic and Electricity DamageDmgElectricitySmall64.png Electricity at the same time.
  • Enemies killed with the initial arrow's Impact DamageDmgImpactSmall64.png Impact damage are ragdolled and launched forward, dealing the same damage to other enemies in their path. In such cases, the explosion will not arm until the slain enemy's corpse strikes a wall, the floor, or any other piece of level geometry. The arrow will then create its detonation field at the point where the corpse 'lands'.
    • This function has an additional effect when using any mod that grants Multishot: should multiple arrows strike the same target simultaneously, a second detonation field will be created at the point where the enemy was originally struck.
  • Punch Through affects the location of the arrow explosions. The weapon's explosions are applied at the final point of contact where the arrow ends rather than whenever the arrow punches through an enemy or object.
  • Shooting a Sensor Bar activates the explosion.
  • Lenz will still have its Cold DamageDmgColdSmall64.png Cold proc effect even if its Cold DamageDmgColdSmall64.png Cold damage is changed into a secondary elemental damage like Viral DamageDmgViralSmall64.png Viral.
  • Additional projectiles caused by Multishot or MirageMirageIcon272.png Mirage's Hall Of MirrorsHallOfMirrors130xDark.png Hall Of Mirrors do not inflict stagger.


  • While the Lenz has innate ammo mutation, its small ammo pool and low ammo conversion rating means players have to make their shots count.
    • Using a companion with Fetch or Vacuum to automatically collect distant ammo pickups will allow the player to keep shooting as long as they can keep killing enemies (and getting ammo drops).
  • Shooting NovaNovaIcon272.png Nova's Antimatter DropAntimatterDrop130xDark.png Antimatter Drop or a companion's ShelterMod TT 20px.png Shelter with the Lenz results in its projectiles instantly skipping to the explosion phase.
  • LimboLimboIcon272.png Limbo's Rift Walk can protect from the explosion without having to escape the area of effect, even if already slowed by the initial proc if the player shifts planes quickly enough.
  • It can be helpful to aim at a nearby surface within the enemy's vicinity and use the Lenz as a timed mine layer. The innate guaranteed Cold DamageDmgColdSmall64.png Cold proc upon the arrow's impact will minimize enemy potential to escape, allowing the bulk of the Blast DamageDmgBlastSmall64.png Blast damage to reach them most of the time.
  • Shadow Stalker is immune to the Freeze debuff from the Cold DamageDmgColdSmall64.png Cold proc, meaning he will be more than fast enough to escape the bubble before the Blast DamageDmgBlastSmall64.png Blast goes off. If you cannot score direct hits, it may be advisable to switch to a different weapon.


  • The Lenz is the first bow that is not silent, and also the first bow that cannot equip ThunderboltMod TT 20px.png Thunderbolt.
  • The Lenz's name may be a nod to Emil Lenz, a Russian physicist who studied electromagnetism. He is most commonly known for Lenz's Law.
  • The pitch of the humming sound played when charging a shot changes with altered fire rates. A higher fire rate results in a more high pitched sound, while a slower fire rate produces a lower pitched sound.
  • The Corpus text on the bow translates to "AUOKZ", its meaning unknown.


Lenz Skins Edit

Patch History[]

Update 28.3 (2020-08-12)

  • Cleaned up the Lenz FX.

Hotfix 27.2.2 (2020-03-06)
Reduced the following AoE weapons Radial Damage Falloff from central impact that were all previously 90%:

  • Lenz: 70%

Update 27.2 (2020-03-05)

Self Damage Changes

We are getting rid of Self Damage and replacing it with something else: instead of Self Damage, it’s now ‘Stagger’. This change completely removes the chance of killing yourself, and instead now creates scenarios where you will interrupt yourself - or ‘Stagger’ - to varying degrees if you aren’t careful.

The degrees of Self-Interrupt start with a small stumble all the way to full knockdown depending on how close you are to the center of explosion. Any Mods referring to Self Damage will be converted to acknowledge Stagger.

With this Self-Interrupt system, we have added dozens of new recovery animations that harness a ninja-like recovery experience. By pressing ‘Jump’ at the correct time, you can execute a ninja-skill-based knockdown recovery to ALL in-game knockdowns. This ninja recovery window is indicated by a glowing FX on your Warframe.

In the original Dev Workshop, we said:
As a result of this overall systemic change, Weapons with Stagger will be getting approximately a 20% buff in Damage, with any weapons with AOE receiving a 50% Radial Damage Falloff from central impact.

This is no longer accurate after continued testing. What we are doing now is:

No damage buffs have been added, but any weapons with AOE are receiving ~20% increase in Radius. Additionally, AOE weapons are receiving a 90% Radial Damage Falloff from central impact. This means on the very outer section of the explosion Radius 10% of the Damage will be dealt. Tactics will be deadly - aim true, Tenno.

Why: Several players brought up the history of the Tonkor and we want to make sure we ship this change in a place that’s conservative in its starting point from a balance perspective. The complete removal of Self Damage does change the pace of destruction with some of the game’s most powerful weapons, so we want to make sure we can iterate upwardly instead of releasing a bonanza of explosions with no other choices.
