The First Descendant Season 4 Adds Karel’s Mothership, Raven, and Trials Mode

The First Descendant, Nexon’s looter shooter, Season 4 is live, bringing the new story chapter “The Great Clash” and a long-teased fight with Karel. The update also adds the Mega Dungeon Karel’s Mothership, new Descendant Raven, a Transcendent weapon tier, Trials mode, balance changes, and several events.

Karel’s Mothership is the main set piece this time. It’s larger than standard Infiltration Operations and has players fighting Karel across three locations, with different attack patterns and dungeon mechanics to learn along the way.

A higher Conquest difficulty for the dungeon opens September 3 and runs through October 15. Clearing it once during that window rewards players regardless of final ranking, with Nexon listing a name card, UI theme, and exclusive weapon skin among the rewards in the official post.

Raven is the new farmable Descendant for Season 4. Completing the episode story provides materials toward unlocking her. Her kit is firearm-focused, doesn’t use MP, and leans on shields and shotgun play. Kyle and Reelan also get balance adjustments in this update.

Trials is a new repeatable roguelite mode built around seven zones. As players move forward, they collect Variable Codes, which work like a deckbuilding layer with effects specific to the mode.

The update also introduces Transcendent Weapons, a new weapon tier that can drop from Normal difficulty and above. Nexon says their base quality rises as players farm them, so repeated drops should trend upward over time.

There’s also a Rotational Build feature that lets players try completed builds prepared by the development team, including in modes such as Trials. Those builds rotate weekly. Season 4 launches alongside challenge missions, login rewards, growth rewards, and a free skin through events.
