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 IconCorpusBCorpus 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 b Cold procs within a eight-meter radius before exploding and dealing a large amount of Blast b Blast damage within six-meters.

The blueprint is available through Energy Lab Research in the Dojo.

This weapon deals primarily Blast b Blast damage.


  • Second highest base damage of all bows, behind Kuva Bramma Kuva Bramma.
  • Tied with Dread2 Dread for highest critical chance of all bows.
  • Arrow explodes on impacting a surface or enemy.
    • Direct arrow impacts have a high chance to proc Impact b Impact and stagger enemies.
    • Initial explosion has a guaranteed Cold b Cold proc in a 7.2 meter radius when impacting enemies or surfaces.
    • 1.3 seconds after the Cold b Cold effect, another explosion occurs in a 7.2 meter radius, dealing very high Blast b Blast damage.
  • Mod TT 20pxHeavy Caliber's accuracy penalty is minimal on this weapon.
  • On kill, bodies will follow the arrow that killed them, damaging anyone in their path and pinning the corpse to walls.
  • Innate Mod TT 20pxArrow Mutation effect.
  • Innate two Naramon Pol polarities.
  • Can benefit from Mod TT 20pxFirestorm, Mod TT 20pxAmalgam Furax Body Count, and Mod TT 20pxCautious Shot.
  • Fire rate mods apply double their bonuses.


  • Innate Blast b Blast damage – less effective against Ferrite Armor and Infested Sinew.
    • Blast b Blast explosion does not occur if the arrow hits allies.
  • Damage cannot be increased with Puncture b Puncture or Slash b Slash mods.
    • The bolt only deals Impact b Impact damage, while the explosions only do Cold b Cold and then Blast b Blast damage, therefore the explosions do not benefit from any physical damage mods.
  • Low status chance.
  • Both explosions inflicts self-stagger.
  • Explosion has linear damage falloff from 100% to 30% from central impact.
  • Arrows have travel time with slight arcing.
  • Slowest charge speed of all bows.
    • Cannot be fired at partial charge.
    • If the bow is charged but not fired for more than a few seconds, the charge will be lost.
  • Low ammo pool.
  • Built-in Mod TT 20pxArrow Mutation effect only restores one unit of ammunition per ammo pickup, regardless of type.
  • Alarming for a bow, making it ill-suited for stealth gameplay.


  • Cannot use the bow-exclusive Mod TT 20pxThunderbolt mod.
  • Having an innate arrow ammo mutation effect, the Mod TT 20pxArrow 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 Mod TT 20pxSniper 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 b Impact, then a large Cold b Cold proc will occur when the arrow hits an enemy or surface, before exploding with Blast b Blast damage. This is why if the user adds a single elemental like Electricity b Electricity, the weapon will show both Magnetic b Magnetic and Electricity b Electricity at the same time.
  • Enemies killed with the initial arrow's Impact b 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 b Cold proc effect even if its Cold b Cold damage is changed into a secondary elemental damage like Viral b Viral.
  • Additional projectiles caused by Multishot or MirageIcon272 Mirage's HallOfMirrors130xDark 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 NovaIcon272 Nova's AntimatterDrop130xDark Antimatter Drop or a companion's Mod TT 20pxShelter with the Lenz results in its projectiles instantly skipping to the explosion phase.
  • LimboIcon272 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 b Cold proc upon the arrow's impact will minimize enemy potential to escape, allowing the bulk of the Blast b Blast damage to reach them most of the time.
  • Shadow Stalker is immune to the Freeze debuff from the Cold b Cold proc, meaning he will be more than fast enough to escape the bubble before the Blast b 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 Mod TT 20pxThunderbolt.
  • 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 in Codex.
  • Lenz' arrow with default colours.

Lenz Skins

Patch HistoryEdit

Update 28.3

  • Cleaned up the Lenz FX.

Hotfix 27.2.2
Reduced the following AoE weapons Radial Damage Falloff from central impact that were all previously 90%:

  • Lenz: 70%

Update 27.2

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.
