The First Descendant: Invasions Quest Guide

The First Descendant: Invasions Quest Guide

As a seasoned player of The First Descendant, I must say that this new update brings a fresh twist to the game with its Invasion Dungeons and the introduction of Hailey as the latest Descendant. However, unlocking these dungeons is not as straightforward as one might think.


The first season of The First Descendant has arrived, introducing new content including a revamped dungeon experience. These dungeons are called Invasion Dungeons and feature new enemies, puzzle elements, and grinding them can help you get your hands on the new Descendant, Hailey, alongside other valuable loot.

To access the Invasion Dungeons, you should finish the seasonal quest series first. This is a fairly straightforward chain of quests that familiarizes you with the new game mechanics and sets you up for what’s to come. While these tasks can be challenging, even for experienced players, here’s a comprehensive walkthrough guide for “The First Descendant” on how to complete the Invasions quest line.

How To Start The Invasions Questline

Generally, during the game, the primary seasonal story won’t be accessible for most players until they finish the main campaign of “The First Descendant“. Upon wrapping up the final mission in the main story, you’ll spot a new quest titled “Mysterious Phenomena” on your log. To kick off this series of quests, engage with Nell in Albion.

Preparation is crucial for successfully finishing the “Mysterious Phenomena” questline, particularly when it comes to handling the challenging final boss battle on your own.

When you converse with Nell in Albion, she will share news about an illness that has affected all Descendants since Ironheart was destroyed. This discussion leads to a two-part side mission, starting with the “Block Kuiper Mining” operation in White-Night Gulch. It’s a unique assignment requiring you to repel waves of Vulgus forces.

Even though the Special Operation isn’t particularly challenging, it might be beneficial to utilize descendants such as Bunny or Viessa to expedite the process.

Moving forward, you’ll encounter the “Inversion Circulation Device” task, which whisks you off to the ancient ‘Mystery Dungeon of Hagios’, set on a challenging difficulty level. Solo players should find this dungeon quite manageable, but if your character build isn’t robust enough, consider joining a public match for additional support.

Altered Design Using Inversion Reinforcement

Once you’ve finished the two tasks given earlier, you need to head back to Albion. There, Anais will assist you in creating a new Inversion Reinforcement Device (IRD). This is a temporary artifact that refreshes every three months, and as you progress through the season, you’ll accumulate Ironheart Particles which can be used to level up your IRD.

As a gamer, I’d say, “The Inversion Reinforcement Device (IRD) grants me access to handy upgrades that are beneficial for not just the seasonal missions, but also for endgame challenges. It’s a must-have tool for advancing in the seasonal storyline.

Rescuing Hailey

After completing the task at Anais, you’ll get your next mission: saving Hailey, the latest Descendant, from a Quarantine Zone dungeon. The adventure begins in a cave adorned with floor plates. Your objective is to illuminate the plates that match symbols on the room’s barricade by using your grapple to reach the marked floating plates and charging them by standing on them.

Make certain to maintain a distance from the common forces known as Vulgus, since they have the ability to disable the plates. Once all three of these plates have been activated, you will then be ready to continue your journey through the dungeon.

Ultimately, you’ll encounter Ledras Infused with Inversion, an elite group of Vulgus who have a protective shield that makes them invulnerable to attacks. To break this shield, find a platform that matches the color of the shield. For example, if the boss has a purple shield, locate and stand on a purple platform. Once the shield is deactivated, you’ll be able to inflict damage.

For the climactic battle, it’s advisable to go at it alone as it’s quite challenging and demands strong defensive skills. Characters such as Ajax, Gley, or Lepic, who are known for their resilience and endurance, would be well-suited for this task.

Unlocking Invasions

Following Hailey’s successful rescue, she makes her way back to Albion. Finishing this task grants access to the Tougher Dungeons in “The First Descendant”, which are challenging adaptations of regular dungeons. The Invasion dungeons share puzzle-solving mechanics akin to those seen in the Quarantine Zone, culminating in a boss battle. To advance through the season, you’ll have to conquer ten of these demanding dungeons.

You’re limited to finishing just four “Invasive Dungeons” each day, and it’s important to note that you can only do so solo. Keep an eye on your map for areas being attacked, as they will be highlighted by a red border.
