Entropic Kuva is a new blue Kuva variant introduced in Warframe’s Iceblade of Narin update. It is unrelated to Rivens and serves as the main currency for obtaining Narin and several associated rewards while helping advance the Zariman storyline.

The resource drops from special Entropic Eximus enemies appearing randomly in Zariman missions on both Normal and Steel Path, with each enemy yielding roughly three to five units. Missions typically contain several spawns, and boosters or difficulty do not appear to increase the amount collected, although Steel Path can offer valuable Arcane rewards. Players can exchange Entropic Kuva with Cephalon Melica at the Chrysalith or Yuvan Peak for Narin parts, her Nunchasa bow, Aksondol pistols, armour, weapon skins and cosmetics.
