Warframe Kuva Lich Guide: Requiem Mods and Valence Fusion

A Kuva Lich is Warframe's personal nemesis system. You make one on purpose, it steals a cut of your loot until you deal with it, and beating it takes a multi-step hunt: learn its secret three-mod passphrase, stab it in the right order, then chase it into space for a Railjack duel. The payoff is a Kuva weapon with a random elemental bonus between 25% and 60%, and a fusion system for pushing that bonus to a perfect 60%. Here's the whole loop, start to finish, with the numbers the wiki actually confirms.

Creating a Kuva Lich

Three things gate the system: finish The War Within quest, hit Mastery Rank 5, and own a Railjack. Once those are done, Kuva Larvlings can show up in any regular Grineer mission with enemy level 20 or higher. Sorties, Void Fissures, Invasions, Quests, and Dark Sectors don't count, but Crossfire and Steel Path missions do. Cassini on Saturn is the classic quick capture for larvling rerolls, since a full run takes a couple of minutes.

The spawn warning is hard to miss: the level's lighting flickers yellow, and you get roughly 30 seconds of killing to force a larvling to appear. Kill enough enemies and one spawns with a transmission from a Kuva Guardian and a red waypoint marked with the Old Blood sigil. Shoot it until it's down on one knee, and an icon above its head shows the exact Kuva weapon your lich would carry. That part matters a lot, because the weapon is the whole reward.

So do you want that gun or not? If the answer is no, walk away. The larvling despawns after 30 seconds, your squad still pockets 100 Kuva at end of mission for downing it, and the weapon you passed on gets dropped from the spawn pool until the other options cycle through. Rejecting is how you fish for a Kuva Bramma or Kuva Nukor without brute-forcing pure RNG. If you like the roll, walk up and Mercy it with your Parazon. In a squad, only the last player who damaged the larvling can take the stab. You can't make a new lich at all while one is already active.

The Warframe you Mercy it with becomes the Progenitor, and that choice locks in three things: the element on the weapon, the lich's ability kit, and which Vengeful ephemera it might carry (a 20% chance at birth, and you get it whether you vanquish or convert later). Pick the frame before you stab, not after. A few common picks off the wiki's table:

| Element | Progenitor Warframes (examples) | | --- | --- | | Impact | Rhino, Gauss, Grendel, Wukong | | Heat | Ember, Inaros, Nezha, Wisp | | Cold | Frost, Hildryn, Gara, Trinity | | Electricity | Volt, Excalibur, Nova, Valkyr | | Toxin | Saryn, Nidus, Khora, Ivara | | Magnetic | Mag, Mesa, Harrow, Xaku | | Radiation | Ash, Loki, Mirage, Nyx |

Toxin and Heat tend to be the popular weapon bonuses, so Saryn and Ember get a lot of larvling duty. Prime versions pass on the same element as the base frame.

The moment it's born, your lich claims Earth and starts taxing you. Every mission you run on its nodes skims a cut of the rewards (credits, resources, blueprints, mods, ayatans, even Kuva), and the tax climbs roughly 0.7% for every node it holds. Requiem Relics, Requiem Mods, and pigments are the only things exempt. Don't panic about the stolen pile, it all comes back the day you finish the hunt. Also worth knowing: a rank 1 lich on Earth runs level 55-75 enemies, but rank 2 on Mars is actually a softer 50-60, and the ladder ends at the Kuva Fortress at rank 5 (90-110). One real warning from the wiki's own tips: MR 5 is the floor, not the target. Bring a real arsenal, because a lich that keeps winning fights keeps leveling up.

Farming Requiem Relics

Requiem Mods are eight strange Parazon mods (plus a ninth wildcard), and they're the only thing that can kill a lich for good. Each one holds three charges. Every time you successfully take down a lich, each mod in your used sequence burns one charge, and at zero charges the mod goes Defiled. Defiled mods can be sold for credits, dissolved for 500 Endo, or you can transmute four of them into one random fresh Requiem. So a steady relic supply is just part of lich life.

The sources, per the wiki:

• Kuva Siphon missions: 50% chance at a Requiem Relic.
• Kuva Flood missions: guaranteed Requiem Relic.
• Thrall kills: 5% chance, any of the four tiers.
• Market: the Radiant Requiem Relic Pack costs 85 platinum and hands you one of each tier pre-refined to Radiant.

Siphon missions show up as their own node type on the two planets nearest the moving Kuva Fortress. Six are active at a time: five normal ones around level 25-35, plus one Flood at level 80-100. The relic is an end-of-mission reward, so you get it even if you ignore the siphon itself, but each alert instance only pays out once (repeat it and you'll see REWARD ALREADY RECEIVED). Popping the actual siphon is bonus money: destroy all four braids by dashing through the Kuva clouds in Operator form (or shooting them with your Amp) and everyone gets 550-700 Kuva, doubled to around 1,100-1,400 on Floods. Let it swallow eight clouds and it teleports away with a shrunk payout, so hurry.

Here's the catch that trips people up: Requiem Relics don't open in normal fissures. They only respond to the special Void Fissures on the Kuva Fortress itself. Those fissures only accept Requiem Relics, so the two systems are glued together. You refine them with Void traces like anything else, 25 traces for Exceptional, 50 for Flawless, 100 for Radiant, and refinement nudges the odds toward the rare slots.

Each tier carries two of the eight mods, both sitting in the uncommon slots:

| Relic | Mods inside | | --- | --- | | Requiem I | Lohk, Xata | | Requiem II | Jahu, Vome | | Requiem III | Ris, Fass | | Requiem IV | Khra, Netra |

The other rewards in the table are Kuva, Riven Slivers, and Exilus Weapon Adapter blueprints, so even junk pulls aren't total waste. Since you need all eight mods before you can even attempt a sequence, most hunters run Floods early on, then top off missing tiers with thrall drops during the murmur grind. Mods are tradeable between players too (8,000 credit tax per trade), so if you're one Lohk short of a full set, trade chat is faster than another dozen Floods.

Solving the Mod Sequence

Your lich has a random passphrase: three different Requiem Mods in a specific order. Murmurs tell you which three mods, never the order, and the order is where the real puzzle lives.

The murmur engine runs on Thralls. Missions inside your lich's influence spawn these blue-glowing goons (look for the red waypoint and the little musical sting when one appears). Mercy-kill one with your Parazon and everyone in the squad gains one murmur. Three filled rings on the lich profile reveal the three mods, one per ring, and each ring costs more grinding than the last. Since the Sisters of Parvos update, DE tuned the requirements so a solo player needs about 12-13 missions of pure thrall hunting on average to expose all three, faster in a squad since murmurs are shared. Testing mods on the lich itself feeds the meter too: a wrong stab pays the whole squad 10 murmurs.

Thrall farming has rhythm to it. Most missions cap natural thrall spawns at around 10 (Survival), while quick Captures only cough up 2-5. The spawn timer runs roughly every 23-45 seconds, and killing fast doesn't speed it up. If the lich itself shows up, it can enthrall 10 extra enemies every 20 seconds, so an angry lich in the room is actually a murmur piñata. Thralls take 25% less damage than normal troops and drop Requiem Relics at that 5% rate, so mercy them all, always.

Getting the lich to appear is its own mini-game. Its profile page has a rage meter (Indifferent up through Enraged), and only thrall kills on your lich's own nodes raise it. The angrier it gets, the more likely it crashes your missions. There's also a Requiem Ultimatum consumable that forces an instant spawn, more on that later.

When it does show up, the fight has rules:

• It has a shield plus three health bars. Beat a bar down to 5% and it stumbles for about 10 seconds, opening a Parazon Mercy prompt.
• The Mercy tests your three slotted mods left to right and stops at the first wrong one.
• A wrong mod anywhere means the lich shakes you off, levels up, and despawns. It gains ground (new planet, more tax) and can rotate its resistances, so a damage type it was weak to can turn into one it shrugs off.
• A correct first mod destroys the current health bar, and broken bars stay broken across encounters. Chip away over multiple meetings if you have to.
• Land all three in order and the lich breaks, burns a charge off each equipped mod, and flees to Saturn Proxima for the finale.

Every Parazon stab that the lich survives still pays the squad Kuva on the spot: 150 at rank 1, then 200, 250, and 300 at rank 4. Small comfort, but it adds up.

Combat-wise, three things matter. Kuva Liches have damage attenuation, so rapid-fire guns and multishot shotguns outperform one big slow cannon shot. Status effects cap at 4 stacks on them (Impact manages 6), their armor can't be stripped, and their shields can. The wiki also flags Banshee's Sonar for damage that bypasses attenuation and Sevagoth's Gloom (Helminth-able) for turning the whole fight into slow motion.

Now the math. Eight mods, three slots, no repeats: 336 possible passphrases, so a blind first stab is 1 in 336. With all three mods known it's just an ordering puzzle, 1 in 6. That's where Oull comes in. It's the ninth Requiem, a wildcard that counts as whichever mod the sequence needs in its slot, and it drops with 25% odds when your own lich flees after the correct sequence (owner only). With an Oull slotted, a from-zero first try improves to 1 in 56.

The wiki's efficient plan works in at most four stabs: fill the first murmur ring before you ever stab, then put the known mod in slot one and randoms behind it. Fail? Move it to slot two. Reveal the second mod and fill the earliest unknown slot with it, shifting failures rightward, and repeat for the third. Worst case you end up swapping the last two mods once, and the fourth stab is a guaranteed kill. Each wrong guess along the way buys 10 murmurs anyway, so failures aren't wasted. The variant with Oull is even tighter: Oull in slot one, the known mod behind it, swap if it fails.

The Final Lich Confrontation

Once you've landed the full sequence, the hunt moves to space. Your weakened lich retreats to Saturn Proxima and a "Kuva Lich Confrontation" node appears, which is a scripted Railjack Skirmish rather than another RNG ambush. You need your own Railjack to start it (a low total Intrinsic level of 5 gets you into Saturn Proxima), and this time you can pick your loadout knowing exactly what's coming, which is the entire point of the reworked flow.

The mission runs in two halves. First, ship combat: whittle down the fighter screen and pop the Gokstad Crewships. Then you board the lich's Grineer Galleon for the actual duel. No more mod guessing here, the passphrase part is done. The lich fights you on a single big health bar, you grind it to zero, and one final Mercy prompt comes up.

That Mercy gives you 20 seconds to make the only real decision in the system: Vanquish or Convert. Hesitate and the game vanquishes for you.

Vanquish kills it for good and pays out:

• Its Kuva weapon, prefixed with the lich's name (something like "Ulogg Stakk Kuva Quartakk"), delivered Ready to Claim in the Foundry, and it bypasses the Mastery Rank requirement on claim.
• The lich's ephemera, guaranteed, if it was born with one (that 20% roll from creation).
• A 25% chance at a Requiem Ultimatum, a gear item that force-spawns your next lich on demand. Great for hunt pacing.
• Every single item it ever taxed from you, returned in full.

Your first lich kill ever also grants the Old Blood Emblem and Sigil, one time.

Convert spares it and turns it into an ally. A converted lich shows up to fight for you after you self-revive from bleedout, scaled at rank × 20 (capped at level 80, or 135 on the Steel Path), dealing triple weapon damage and sticking around at least two minutes. With Command Intrinsic rank 8 you can also station it as Railjack crew, where it's locked to the Defender role and scales at rank × 15, so a rank 5 lich guards your ship at level 75 with fat health and shields.

The trade economy runs entirely on converts. A converted lich can be traded exactly once, inside a clan dojo's Crimson Branch room, and the buyer must have no active lich of their own. Right-click its token to preview the stats before committing. Once traded, the lich becomes the buyer's active nemesis with a freshly rerolled requiem sequence, and they have to beat it themselves to claim the weapon. That's how players sell specific weapons with specific bonuses and ephemeras without ever touching the weapon directly.

Using Valence Fusion

Kuva weapons roll their elemental bonus between 25% and 60% at creation, weighted so low rolls are more common, which means your first Bramma is probably a 33% something. Valence Fusion is how you fix that. It merges two copies of the same Kuva weapon (or two of the same Tenet weapon) into one stronger copy, and you'll find it under the Actions button in the modding screen.

The math is simple: the result takes the higher of the two bonuses and multiplies by 1.1, hard-capped at 60%. And anything that lands at 58% or above snaps straight up to 60%. Fusing a 40% Heat Kohm with a 52% Radiation Kohm gets you 57.2%, every time, regardless of which is the donor. Since a couple of updates in 2021, you also get to pick which element survives when the two differ, so a garbage-element high-roll duplicate is still perfect fusion fodder for the element you actually wanted.

Two rules keep people from ruining their guns. First, investments don't transfer. Catalyst, Forma, stance Forma, lenses, all of it dies with the donor. Always run the fusion from your built-up weapon and feed it the naked duplicate, not the other way around. Second, the donor is consumed, period, and the game makes you type FUSE to confirm so you can't do it by accident.

How many liches deep is a perfect weapon? Depends entirely on your starting roll:

| Starting bonus | Max fusions to hit 60% | | --- | --- | | 58.0% | 0 (auto-rounds up) | | 52.8% | 1 | | 48.0% | 2 | | 43.6% | 3 | | 39.7% | 4 | | 36.1% | 5 | | 32.8% | 6 | | 29.8% | 7 | | 27.1% | 8 | | 25.0% | 9 |

So even the worst possible 25% roll reaches god-tier in nine donors. In practice most people stop somewhere in the 50s, because each extra point costs another full lich hunt.

A few weapon facts that pair well with fusion. Kuva weapons cap at rank 40, gaining 2 ranks per Forma for the first five polarizations, which is 4,000 mastery points each and up to 80 mod capacity with a Catalyst. The innate elemental bonus is base damage applied after regular elemental mods, which matters when you're planning combinations on guns like the Kohm. And all 19 Kuva weapons have an equal chance at larvling spawn, so a targeted hunt plus the reject-reroll pool gets you duplicates of the one you're raising without too much pain.

The efficient endgame loop, then: spawn larvlings on a progenitor frame with your element until you get the weapon you want with a decent roll, hunt it, vanquish it, repeat for donors, and fuse upward. The 58%-auto-rounds rule is the sneaky shortcut worth remembering: a single 58% roll from a strong lich is functionally a perfect 60% weapon, no fusion chain required.
