If you’ve spent any time exploring Fontaine’s underwater areas or completing event quests in Genshin Impact, you’ve probably picked up a handful of Luna Sigils without knowing exactly what they’re for. A lot of players let these small, glowing blue tokens sit in their inventory for weeks because they don’t stumble on their use case by accident, and wasting limited event or exploration rewards is the last thing you want when you’re grinding for primogems or character upgrade materials. Figuring out where to use Luna Sigils in Genshin Impact can unlock some surprisingly valuable rewards, even if you only have a small stockpile saved up.
Where to Use Luna Sigils in Genshin Impact: Core Exchange Locations
Luna Sigils have two primary exchange points, one permanent and one event-specific, so you don’t have to worry about missing out on core rewards if you don’t log in during every limited event. The first permanent location is the Luna Sigil Exchange NPC, Marinette, who stands just off the main plaza near the Fountain of Lucine in the Court of Fontaine. She accepts Luna Sigils earned from underwater exploration, hidden chests, and Fontaine world quests, and her shop stays available across all patches once you unlock the Court of Fontaine. You will need to complete the first act of the Fontaine Archon Quest, “Prelude of Blancheur and Noirceur”, to get access to her shop, so don’t panic if you don’t see her when you first arrive in the region.
The second use case is for limited-time Fontaine event shops. Most Fontaine-themed events feature Luna Sigils as a bonus reward for completing event challenges, and you can spend these tokens in the dedicated event shop for the duration of the event. These event-exclusive Luna Sigils are separate from the open world ones, and they expire as soon as the event ends, so you can’t save them for later use. If you earn Luna Sigils from an event notification, make sure you spend them before the event wraps up to avoid losing them entirely.
Top Rewards You Can Unlock With Luna Sigils
Many players skip spending Luna Sigils because they assume the rewards are low-value, but that couldn’t be further from the truth. Both the permanent and event shops have high-value resources that can save you hours of grinding in the open world. Primogems are the most sought-after reward, with Marinette’s permanent shop offering 60 primogems per account, and most event shops carrying 120+ primogems for limited runs. You can also pick up character ascension materials for popular Fontaine units like Furina, Neuvillette, and Lyney, plus talent level-up books, mystic enhancement ores, and millions of mora if you need extra currency for upgrades.
Event shops also carry exclusive rewards you can’t get anywhere else, including limited-edition namecards and Serenitea Pot furnishing blueprints that are only available for the duration of the event. If you care about customizing your profile or teapot, these are well worth prioritizing over generic resources. To make sure you get the most out of your Luna Sigils, follow this reward priority order:
- Primogems: Always grab these first, as they’re the only currency that lets you pull for limited 5-star characters and weapons
- Character ascension materials for units you’re currently building, to cut down on grinding time in open world boss fights
- Exclusive namecards and furnishings, since these are often limited-time and won’t be available once the event or shop rotation ends
- Mora and enhancement ores, only if you’ve already claimed all the rarer, limited rewards first
It’s easy to waste Luna Sigils on low-value resources you can farm for free in the open world, so sticking to this order will make sure you don’t regret your purchases later. I once spent 80 Luna Sigils on mora right before an event shop dropped a namecard I’d been wanting for months, and I had to grind extra challenges to earn enough tokens to grab it before the event ended. Don’t make that same mistake.
Common Mistakes to Avoid When Using Luna Sigils
Even players who know where to spend their Luna Sigils often make simple errors that cost them valuable rewards. The biggest mistake is hoarding event-specific Luna Sigils for later. Unlike open world Luna Sigils, event variants disappear from your inventory the second the event closes, and you can’t get them back. Set a reminder on your phone to spend any event Sigils 24 hours before the event ends if you’re prone to forgetting.
Another common mistake is spending Sigils on resources you already have in surplus. If you have 15 million mora saved up, there’s no point wasting 10 Luna Sigils on 50,000 mora when you could get a talent book you actually need for your main DPS unit. Take 30 seconds to check your inventory before you make any purchases to make sure you’re not wasting tokens on items you don’t need. Don’t forget to check Marinette’s shop every patch too, as HoYoverse occasionally adds new rewards to the permanent rotation, including ascension materials for newly released Fontaine characters.
You also don’t need to go out of your way to farm every single Luna Sigil in the open world if you only care about primogems. Marinette’s permanent shop only has 60 primogems available total, so once you collect enough Sigils to claim those, you can stop hunting for extra chests unless you want the other rewards in her shop. There’s no pressure to 100% every underwater zone if you don’t care about furnishing blueprints or extra mora.
Quick Tips to Farm More Luna Sigils Fast
If you’re running low on Luna Sigils to grab the rewards you want, there are a few easy ways to farm them without spending hours grinding. First, prioritize hidden underwater chests in Fontaine’s open sea areas. Most medium and hidden chests in underwater zones drop 1-2 Luna Sigils each, and there are over 200 chests across the region to unlock. You don’t need to fight any enemies to open most of these chests either, so you can grab them quickly even if you’re underleveled for Fontaine content.
Next, finish all short Fontaine world quests related to the Melusine villages and underwater research stations. Many of these quests take 10 minutes or less to complete, and they give 5-10 Luna Sigils as a completion reward, plus unlock more hidden chest locations that have extra Sigils. You can find these quests by talking to random NPCs around the Court of Fontaine and Melusine villages, or by following blue quest markers on your map as you explore.
Finally, participate in all limited-time Fontaine events, even if you don’t plan to complete every challenge. Most of these events give out dozens of Luna Sigils just for clearing the first few easy challenges, so you can earn enough to grab the primogems and ascension materials from the event shop with minimal effort. If you’re a new player who just unlocked Fontaine, you can easily collect over 300 Luna Sigils in your first week of exploring the region if you prioritize chests and short world quests, which is more than enough to claim all the high-value rewards from Marinette’s permanent shop.
At the end of the day, Luna Sigils are one of the most underrated open world currencies in the game, and spending them wisely can save you hours of grinding for rare resources. You don’t have to go out of your way to farm every single Sigil available, but taking 10 minutes to locate the exchange shops and claim the highest-priority rewards is always worth the time. If you’ve been letting these tokens collect dust in your inventory, now’s the perfect time to figure out where to use Luna Sigils in Genshin Impact and claim the rewards you’ve already earned.
