If you’ve spent any time roaming The First Descendant’s post-apocalyptic maps, you’ve almost certainly seen other players dominate boss fights with Luna’s gravity-based abilities, and wondered how to get Luna in The First Descendant for yourself. I main support characters in almost every looter shooter I play, so I was desperate to get my hands on Luna as soon as she dropped, and I tested every possible shortcut to unlock her faster. She’s far from a basic starting character, but her crowd control and single-target damage output make her one of the most sought-after descendants in the entire game right now. I spent three days testing different unlock paths last month, skipping a bunch of unnecessary side quests to cut down the grind time by almost 40% compared to generic guides I found online. This guide will walk you through every step you need to follow, no hidden hoops or missed prerequisites to waste your time.
How to Get Luna in The First Descendant: Core Prerequisites You Can’t Skip
Before you even think about fighting the boss required for Luna’s unlock, you need to tick four non-negotiable boxes. A lot of guides skip over these requirements entirely, leading players to waste hours hunting for a quest that won’t even appear for their account yet. I made this exact mistake early on, grinding Void Shards for two days before I realized I was 5 levels too low to pick up her unlock quest. Here’s exactly what you need first:
If you meet all four of these requirements, you’ll see Luna’s dedicated unlock quest “Gravity’s Call” pop up on the mission board in the main hub, right next to the daily challenge listings. Accept the quest, and it will mark the boss arena location on your map in the northern section of the Frost Wastes.
Beating the Gravity Core Boss Fight for Luna’s Unlock Item
The quest requires you to beat Graviton, a level 35 void boss that lives in a hidden ice cave in the Frost Wastes. The fight has two distinct phases, and if you don’t know the mechanics, you can easily wipe even with a full team of high-level players. I tried using my go-to fire shotgun for my first run, and I could barely chip 10% of the boss’s health before I died, so trust me on these tips.
In phase one, Graviton will shoot slow-moving gravity orbs that deal area-of-effect damage when they hit the ground. Dodge to the side to avoid them, and focus all your fire on the glowing blue core on its chest. Don’t use fire-based weapons for this fight, because Graviton has 70% fire resistance, which will make your damage almost negligible. I recommend using a lightning-based assault rifle or a rocket launcher with void damage for the fastest clears. If you’re running solo, bring at least two revive kits, because stray orbs can one-shot you if you get caught off guard.
Once you drop Graviton to 50% health, phase two starts. It will create floating gravity wells that pull you toward them, and if you get too close, they’ll drain your health extremely fast. To disable the wells, you have to shoot the small floating blue crystals that spawn around the arena. If you’re playing co-op, assign one player to take out these crystals exclusively so the rest of the team can focus on dealing damage to the core. The fight takes 8-12 minutes on average, depending on your team composition and gear level.
Once you beat Graviton, you’ll get the Luna Core Unlock Token, which is the key item you need to unlock her. Don’t leave the arena right after the boss dies, there’s a small chest in the back of the cave that has extra Void Shards and a rare Luna skin blueprint, so make sure you grab that before you fast travel back to the hub.
Final Steps to Unlock and Equip Luna
Once you have the Luna Core token, head back to the main hub and go to the Descendant Research terminal, which is right next to the upgrade bench. Interact with it, select Luna from the locked descendants list, and turn in the token plus the 15 Void Shards and 2 million credits you collected earlier. The unlock process takes 10 real-time minutes, but you can speed it up by using 100 premium currency if you don’t want to wait.
I don’t recommend wasting premium currency on this, though, because 10 minutes is enough time to run a quick daily challenge and earn extra credits while you wait. Once the unlock is complete, you can equip Luna from your character selection screen. Make sure you run her first character quest immediately after unlocking her, it only takes 15 minutes and gives you a free legendary gravity gauntlet that’s perfectly tuned for her ability set. A lot of players skip this quest and end up grinding for weapons that are worse than the free one you get here, so don’t make that mistake.
Her first ability, Gravity Pull, is perfect for crowd control in co-op missions, so test it out in a low-level Void Rift first to get used to her playstyle before you jump into high-difficulty content. She has a slightly steeper learning curve than starter descendants like Ajax, but once you master her ability timing, she can single-handedly carry most boss fights by pulling enemies out of cover and disabling high-threat attacks.
Common Mistakes to Avoid When Unlocking Luna
Even with a clear guide, it’s easy to make small mistakes that add hours of unnecessary grind to your unlock process. I made almost all of these mistakes on my first attempt, so I’m listing them here to help you avoid the same frustration.
First, don’t try to farm the Graviton boss before you hit level 32, even if you get invited to a co-op run by a higher level player. The Luna Core token only drops if you meet the level prerequisite, so you’ll waste 10 minutes of your time for no reward. Second, don’t scrap all your excess gear for upgrade parts, as I mentioned earlier, selling it will get you the 2 million credits way faster. I made this mistake on my first attempt, and I had to grind extra missions for two hours just to make up the credit difference.
Third, don’t ignore the floating crystals in phase two of the Graviton fight. If you let three gravity wells spawn at once, the entire arena will get covered in damage zones, and you won’t have anywhere to stand to avoid attacks. Assign one team member to focus solely on crystals if you’re running co-op, it will make the fight 10x easier. Fourth, don’t forget to pick up the post-fight chest in the Graviton arena. I missed it on my first clear, and I had to run the entire fight again just to get the skin blueprint, which was a huge waste of time.
Finally, don’t skip Luna’s introductory character quest. The free legendary gauntlet you get is viable all the way up to level 50 content, so it’s easily worth 15 minutes of your time. You can always grind for better weapons later, but this free drop will let you use her full kit immediately without extra farming.
Unlocking Luna is well worth the 6-8 hours of total grind time, especially if you prefer playing support or crowd control roles in co-op missions. Once you know how to get Luna in The First Descendant, you can skip all the unnecessary steps that waste most new players’ time, and start using her game-changing gravity abilities to dominate boss fights and carry your team through high-difficulty content. Don’t rush through the prerequisites, take time to farm the right materials and gear before you attempt the Graviton fight, and you’ll have her added to your character roster before you know it.
