Karel’s Final Showdown Arrives in The First Descendant Update 1.4.0

Comments

Nexon has rolled out Update 1.4.0 for The First Descendant, its looter shooter, on Steam, Xbox, and PS5. The update adds the Mega Dungeon Karel's Mothership alongside a climactic Main Quest confrontation with Karel.

The new Main Quest centers on the final showdown between the Descendant Corps and Karel. Completing it grants a special Chest Attachment and an Ultimate Alignment Device. Karel's Mothership hosts the final battle against Karel, with Vulgus from all Legions and three Legion Commanders appearing in the dungeon.

What's in the update

  • Karel's Mothership Mega Dungeon: Vulgus General Karel and forces from all Legions appear alongside three Commanders: Torisar the Curse-Spreader, Pattern-Enhanced Arche Slayer, and Reborn Alzaroke. Defeating Torisar or Reborn Alzaroke grants the Descendant a temporary special ability.
  • New Champion mechanics: Elemental Vulnerability effects and the half-moon Explosive Marker introduce new threat patterns. Weak Point Damage Adjustment Value does not apply to monsters in this dungeon.
  • Three difficulty tiers: Normal unlocks after the Main Quest. Hard requires one Normal clear, while Public Operations require 81,580 Arche Activity. Conquest is limited-time content running from after the September 3, 2026 patch until before October 14, 2026, 22:00 PDT.
  • Loot tables: Transcendent Weapon Loot ranges from Quality 251 to 400 on Normal and Quality 271 to 400 on Hard, alongside Ancestors Module Loot, Rare Alignment Devices, and new Trigger Modules.
  • Trials mode: A repeatable roguelite battle mode arrives with two new Commanders, Antithese and Vorax, and a Variable Code system that carries selected effects into subsequent rounds.
  • Weekly rewards: Karel's Mothership: Hard joins the weekly content list. One clear awards 300 Merit Tokens and 150,000 Kuiper Shards.

The patch notes were revised on August 20 for Hard difficulty rewards and on August 23 for the obtainable Quality range for Onslaught in the Transcendent Weapons table.

Karel's Mothership ties the new dungeon directly to the Main Quest's showdown with Karel, while Trials offers repeatable combat with escalating rounds, randomly connected combat zones, and Variable Codes that can be combined to enhance battle power.
