Entropic Kuva is the resource at the center of Update 44: Iceblade of Narin, and it is the free path to Narin, the game’s 66th Warframe. It is a separate currency from regular Kuva, so it has nothing to do with Riven rerolls. Its only job right now is buying Narin’s blueprints and her signature gear from Cephalon Melica.
Quick answer: Kill Entropic Eximus enemies in any Zariman mission to collect Entropic Kuva, then exchange it with Cephalon Melica at Yuvan Peak or the Chrysalith.
Requirements before you can farm and spend it
You need access to the Zariman to farm the resource, and access to Cephalon Melica’s shop to spend it. Both come down to finishing specific quests first.
- Angels of the Zariman unlocks the Zariman Ten Zero missions where Entropic Eximus spawn.
- Whispers in the Walls is the second required quest for Melica’s shop.
- You must complete both quests to unlock Yuvan Peak and Melica’s Classroom Supplies inventory.
- After completing both tasks, Melica sends an inbox message directing you to Yuvan Peak on Earth.
If either quest is missing, finish it first. Entropic Kuva has no other use, so there is no point stockpiling it before the shop is open.
Where Entropic Kuva drops: killing Entropic Eximus
Entropic Kuva has only one source: Entropic Eximus enemies. These new foes can appear in Zariman missions on either Normal or Steel Path, and each defeated one yields roughly three to five Entropic Kuva. Their spawn rate is higher than that of other Eximus types, so most runs contain several to track down.
Each Entropic Eximus is wrapped in a protective bubble of Kuva and throws destructive orbs at you. Shooting from range does little, so the reliable counter is to step inside the bubble and attack from within. They hit hard, so keep moving once you are inside.
These are resilient foes. Your Operator can damage them, but at a reduced rate, so your strongest tool is melee. Visiting Yuvan Peak and interacting with Narin’s Crest and iceblade grants a boost to your Melee Damage against them, which makes clearing the bubbles far quicker. Bring a strong melee build rather than leaning on guns.
If you engage a Void Angel during a Zariman run, extra Entropic Eximus units join the fight, so be ready before you start it.
Resource Boosters, Drop Chance Boosters, and companion mods do not increase how much Entropic Kuva you pick up. The amount is fixed per kill and does not change with difficulty, so the fastest farm is simply killing more Eximus.
Best Zariman missions to farm Entropic Kuva
Since Entropic Eximus can spawn on any Zariman node, the fastest farm is the mission with the most enemies in the least time. Endless and high-density modes keep the spawns coming, while Exterminate is best for quick, repeatable runs. Playing in a full squad raises spawn rates, so a group clears more Eximus per run than a solo player.
| Node | Mission type | Best for |
|---|---|---|
| Tuvul Commons | Void Cascade | Sustained enemy density |
| Oro Works | Void Armageddon | Waves funneled to one point |
| Everview Arc | Void Flood | Steady enemy stream |
| Halako Perimeter | Exterminate | Fast, repeatable runs |
Bring a Warframe that clears rooms quickly to speed things up. Narin’s blueprints also drop directly from these missions as rewards, so running a variety of nodes can hand you parts alongside the currency. On Steel Path, the Zariman doubles as a strong Arcane farm, and a Mod Drop Chance Booster helps there even though it does nothing for Entropic Kuva itself.
Spending Entropic Kuva with Cephalon Melica
Cephalon Melica accepts Entropic Kuva through her Classroom Supplies inventory. You can reach her at Yuvan Peak on Earth, tucked among the ice formations near the mountain, or aboard the Zariman in the Chrysalith. Both point to the same shop, and each option offers fast travel to the other, so use whichever is closer.
Her stock covers Narin’s frame parts, her signature Nunchasa bow, her Aksondol dual pistols, plus armor, weapon skins, decorations, and cosmetics. If your goal is the Warframe first, buy her four blueprints before anything else. The full set costs 790 Entropic Kuva.
| Narin blueprint | Entropic Kuva cost |
|---|---|
| Narin Blueprint (main) | 400 |
| Chassis | 130 |
| Neuroptics | 130 |
| Systems | 130 |
| Full set | 790 |
After buying the four blueprints, craft the Neuroptics, Chassis, and Systems in your Foundry, then use those finished parts to build the main Narin blueprint. Save any leftover currency for the Nunchasa and Aksondol parts or Melica’s cosmetics, since those blueprints also cost Entropic Kuva. Entropic Kuva is untradeable, so you cannot buy it from other players, and the resource has no sell value.
You will know the loop is working when Entropic Kuva appears in your inventory after killing Entropic Eximus, and when Melica’s Classroom Supplies lets you purchase a blueprint. Once a Narin part shows up in your Foundry ready to build, you are on the final stretch to adding the frame to your collection.
