–Lieutenant Lech Kril

Lieutenant Lech Kril is the final boss of Ceres, and makes an appearance on Phobos alongside Captain Vor as a dual boss battle on the planet. A revered war hero to the Grineer, Lotus has targeted Kril so that his death could create possible instability within the Grineer and intimidate them, although she also fears he may become a martyr with Grineer riled up to avenge his death as a result. His status as a "war hero" is rather strange considering his apparent low rank in the Grineer military, although his near impenetrable body suit and massive temper may prove that he is indeed as ruthless as Grineer say he is.

  • He can be found on the mission Exta on Ceres and Iliad on Phobos.
    • On Ceres, after defeating him and finishing the mission, you receive a Frost Helmet, Chassis or Systems blueprint. Upon death, Lieutenant Lech Kril has a chance of dropping an Orokin Cell.
    • On Phobos, he rewards Miter parts and its blueprint, or the Twin Gremlins blueprint. He also drops blueprints for Trinity components. He has two phases, first being Ice and the second Fire, which he will enter after his cryo pack is destroyed four times.


Lieutenant Lech Kril wears a unique set of body armor and wields the Gorgon and Brokk. This boss fight comes in two phases, with different abilities and attacks for each phase.


Lieutenant Lech Kril, like other bosses, has unique taunts. Here is a list of them:

  • And I will strike down upon (User) with great vengeance and furious anger!
  • The sound of hammer shattering ice is pure auditory perfection.
  • Beneath those suits exist flesh. Flesh bleeds. (User) bleeds.
  • I have seen and conquered many clans. (Clan) will be next!
  • Does that second-skin peel away just as easy as the first?
  • Grineer immortality begins with the strike of my hammer!
  • I am Lieutenant Lech Kril. My hammer awaits your skull.
  • I forgot my nails... I guess (User) will have to do!
  • Trust me when I say you won't feel a thing.
  • You ever get hammered in that suit?
  • Hold still and I'll make this quick.

Lieutenant Lech Kril's battle is split into two phases, the latter phase starts after his coolant pack has been completely destroyed. He generally wields a Gorgon and a Brokk hammer.

Phase 1Edit

Kril is completely invincible. He will generally use his Gorgon throughout the first battles on ranged targets, though occasionally he will shoot Freeze at them. He will resort to his Brokk to knock a target away when they get too close. Alternatively, he will slam the ground with his hammer, casting Ice Wave. Both abilities guarantee a Cold b Cold proc.

Kril prefers to stay his ground and tank all firepower instead (though it limits his mobility), unlike most Grineer personnel. He is only vulnerable to damage when all four coolant tubes on his cooling pack (on his back) are destroyed, which will then shift the battle to Phase 2.

Phase 2Edit

Lieutenant Lech Kril will burst into fire and put away his Gorgon and equip his Brokk hammer, resorting to full-melee while turning all of his Cold b Cold based ability into a heavy Heat b Heat damage. Alternatively, he may slam down Fire Wave which guarantees Heat b Heat proc or throw his hammer at long range targets as a heavy boomerang.

Despite still possessing heavy armor, his melee capability and speed increases by a great margin. He can even catch up to a Tenno and his swing speed is noticeably faster. One must be careful as a single strike from him has lethal potency and can down an inexperienced Tenno.

In GeneralEdit

In Phase 1, Lech Kril is impervious to damage and the coolant pack on his back must first be destroyed to render him vulnerable. Using a successful slam attack on his pack or shooting his pack when the center of it is lit will cause one of its four pipes to pop off and wave frantically in the air. In this state, the next time Lech Kril attempts to slam his hammer or throw an Ice Dart, he will be frozen solid (In order to get him to do so, you may either wait or back away while blocking with your melee weapon); attacking the pack while he is frozen will destroy the dislodged pipe. This process of dislodging a pipe, freezing him and destroying the pipe must be repeated three more times to destroy all four pipes, at which point he becomes vulnerable to damage. 

It is recommended to always stay close to cover during this phase. Although his Freeze can be dodged by keeping an eye on Kril's motion, being close to cover can save you if you do accidentally get hit by a Dart and become frozen. Being caught out in the open while frozen can result in getting heavily damaged or killed by Kril's Gorgon.

In Phase 2, while he only can be taken down mostly by kiting, most of his attacks are predictable. His Brokk will glow brightly when thrown, note that Kril is stationary while throwing the hammer and until it returns, giving an opportunity to damage him. When using his Fire Wave, Kril will lift his hammer before slamming it to the ground, giving players time to dodge.

If Kril charges at you and he's faster than you, do not keep running away. Instead, run towards him and flank besides or over him. This will make him try to swing his hammer down on you, thus temporarily stopping his movements, while getting away from his attack.

Utilizing Warframe AbilitiesEdit

Ash's Smoke Screen, Loki's Invisibility or Shade's Ghost will cloak the player, creating a big opportunity for you to destroy his cryo pack.

Loki's Decoy and Saryn's Molt are also invaluable for distracting Lech Kril's gunfire while exposing him to attacks from the Tenno.

Frost's Snow Globe slows Lech Kril's ice-based melee attacks, allowing his target to walk out of the way while increasing the length of time when he is vulnerable during his first phase.

Rhino's Rhino Stomp can be used to disconnect the pipes without having to shoot the back.


  • Lieutenant Lech Kril is a revered war hero among the Grineer. While his assassination will result in increased stability for the solar system and intimidate the rest of the Grineer, Lotus dislikes the fact that it will also make him a martyr to his people.
  • He looked like a larger Grineer Butcher before Update 7, and wielded a Fragor instead.
  • Currently, there is a chance that a glitch could happen after one or more of his cooling tubes has been severed, causing the battle against him to become stuck on Phase 1, in which the Cryo pack cannot be damaged further. This glitch happens randomly, no matter which Warframes are present (tested)
  • Kril appears in the Warframe Open Beta trailer, though still wielding the Manticore, rather than the current Brokk.
  • He was the first boss to undergo a major revamp, receiving a more complex boss battle and unique voice-acting and animations.
  • Prior to Update 7.5, he used the Manticore instead of the Brokk.
  • He also was the first boss to have a special death animation. Prior to Update 8, on death, he would fall flat on the ground like a downed player before actually dying. It took a little time for him to bleed out on his own, but one could finish him to shorten the time. After Update 8, he now has a new death animation where he falls to his knees and collapses before erupting in a fiery explosion.
  • Lieutenant Lech Kril's taunt "And I will strike down upon (player name) with great vengeance and furious anger!" Is a reference to a scene in Pulp Fiction, in which Samuel L. Jackson states the same as a quote from the Bible's book Ezekiel 25:17 (Which was a dramatized version from the original Bible quote, "And I will execute great vengeance upon them with furious rebukes; and they shall know that I am the LORD, when I shall lay my vengeance upon them.")
  • As of Update 11, his shields can be damaged during Phase 1. Although he is still invulnerable, bleeding effect from Slash-based weapons will directly damage his health.
  • His rank is somewhat unusual for a supposed 'war hero', as Lieutenants are generally lesser-ranking commissioned officers in current military terms, only three or four steps above the lowest possible rank. It is possible that Kril has not been an officer for long, or that Grineer officers are assigned their ranks/titles on a different basis; perhaps based off the size of the force they command or their overall long-term experience, rather than personal combat experience. Alternately, his status as a war hero may be entirely fabricated as a propaganda campaign, and his title/rank chosen on purpose.

Bugs Edit


Kril saying his name incorrectly.

  • It is possible to stealth kill Kril and glitch the game out causing the mission to freeze and leave Vor as the only boss left in Phobos. Any attempt to kill Vor will be futile as Vor becomes invisible and it is impossible to kill him.
  • Sometimes when Kril says the phrase, "I am Lieutenant Lech Kril. My hammer awaits your skull." it will be replaced with, "I am /Lotus/Language/Game/Question Mark. My hammer awaits your skull."
    • This is actually the location in the game files where the phrase is located. Why this occurs is currently unknown.
