Nexon pushed Patch 1.3.15 for The First Descendant on January 7, 2026 at 23:00 PST. The update focuses on a few tight fixes that affect how certain skills block player vision, adjusts how many Superconductive Cooling Units drop across multiple activities, and lowers the difficulty of some battle pass daily challenges.
Players who run Valby or Hailey builds will see the biggest immediate difference, while those farming Infiltration Operations, Sigma Sector, Void Vessel, Axion Plains, or Void Erosion Purge should notice changed reward math. This continues Nexons steady post-launch cadence following recent updates such as Patch 1.3.9.
