Sea of Bygone Eras

An underwater view of the Sea of Bygone Eras region in Fontaine. The submerged ruins of Remuria hide countless treasures and puzzles beneath their coral-coated arches. Whether you’re a completionist for 100% exploration or just want to get those Primogems and ascension materials, we’ve got you covered. Below we’ll go over what rewards you can get, the service options, requirements, and some expert insights on mastering Sea of Bygone Eras in Genshin Impact.

Exploring the Sea of Bygone Eras isn’t just for pretty scenery – it yields tons of rewards for your Genshin Impact account. By letting Genshin Impact boosting service from ChaosBoost do the work for you, you won’t miss out on any of these goodies. Here’s what you can fish up from the depths:

1. Primogems & Adventure EXP: Every arc and chest gives you Primogems and AR EXP. You’ll get hundreds of Primogems for Wishes.
2. Shrine of Depths Loot: Two shrines have Luxurious Chests at 40 Primogems each. They also drop high tier artifacts, ascension materials, and Hydro Sigils.
3. Treasure Chests & Collectables: Over 100 chests (Exquisite, Precious, Luxurious) with Mora, EXP books, and rare items. Hidden achievements and secret lore for completionists.
4. Resources and Materials: Get Varunada Lazurite, artifact sets, and special quest items. These don’t need extra farming.

With all that, venturing into the depths is totally worth it. By using our Genshin Impact boosting service you won’t just get the satisfaction of 100% exploration map – you’ll leave with a boosted inventory and boosted progression. In short, you’ll emerge from the deep like a well fed Otter, full of Primogems, loot, and the pride of conquering one of Genshin Impact’s hardest regions.

Every Genshin player is different so our Sea of Bygone Eras boosting service comes with flexible options. Whether you’ve only unlocked the region and feel overwhelmed or you’re 70% explored and just can’t find those last few collectibles we have a service option for you. Here are some popular choices you can pick (or mix and match):

• Full 100% Exploration: Covers all quests, chests, puzzles, waypoints, and shrines. Ends with 100% exploration statistic and all rewards.
• Partial Exploration & Custom Tasks: For those who have made progress but need specific help. Our team will only complete the tasks you request.
• Region Unlock & Story Completion: Ideal for unaccessed Sea of Bygone Eras. Quests like “The Shadow Over Petrichor” and “Underwater Nocturne” will be completed, opening Remuria fully.
• Shrine and Boss Farm: Targets two Fontaine shrines and “The Knave” boss. Shrine loot and talent materials will be obtained without full exploration.

Each of these options will be handled with the same level of care and expertise. You can also talk to us to create a customized boosting plan. For example, you might combine the Story Completion + Full Exploration if you literally haven’t touched the region at all and want us to take it from zero to hero. Whatever you choose, ChaosBoost will make it a smooth and efficient Genshin boost so you can enjoy the Sea of Bygone Eras content stress free.

Before you hand over your diving gear to us, let’s double-check that you meet the necessary requirements for the Sea of Bygone Eras boost. Genshin Impact has a few built-in conditions for accessing this region, and to perform the service, we have a couple of our own guidelines too. Here’s what you’ll need:

• Adventure Rank 40+: We recommend your account to be at least AR 40 (the minimum to have unlocked Fontaine’s content comfortably). The world quests that unlock Sea of Bygone Eras typically require around AR 35 to trigger but AR 40 ensures you have access to all Fontaine areas and can handle the enemy levels in Remuria’s depths. Essentially your Genshin Traveler needs to have enough experience under their belt to go underwater. (If you’re a bit underleveled let us know – we might be able to include an AR boost or adjust world level settings.)
• Fontaine Access Unlocked: You must have access to the Fontaine region and its underwater mechanics. In practical terms this means you should have progressed far enough in the main Archon arc to enter Fontaine (and obtained the ability to swim underwater). If you can roam around in the Court of Fontaine or have done any Fontaine quest you’re good to go. If not we can guide you on how to meet this requirement before we start the boost.
• World Quest Progress: Ideally your account should have the Canticles of Harmony world quest series available or started. This includes story arcs like “The Shadow Over Petrichor” (opens the Nostoi region) and “Underwater Nocturne” (which unlocks Sea of Bygone Eras itself). If you haven’t done these quests don’t worry – our Genshin boosters will complete them for you as part of the service (as long as you meet the AR and story access requirements above). Just be aware that unlocking the region is part of the service if not already done and it will involve doing those quests.
• Account Credentials & Offline Time: As with any boosting service you’ll need to provide us access to your account (for PC/Mobile, your HoYoverse login; for PlayStation, account link or co-op arrangement if possible). You should not log in during the boost period to avoid any disconnects. We use secure connections (VPNs matching your region) to keep your account safe.

Once you meet these requirements you’re good to go! If you’re unsure about any of the requirements feel free to reach out – we can often help or guide you on how to prepare your Genshin account for boost. We want to make the process as smooth as possible so you can sit back, relax (maybe watch a show or grind another game), and come back to a fully explored Sea of Bygone Eras in your Genshin Impact account.

Unlocking the Sea of Bygone Eras is a Genshin Impact mini-adventure in itself. Genshin Impact doesn’t let you simply swim into this region from the get go – you need to follow a story chain and meet certain criteria to gain access. If you’re curious about the unlock process (or maybe you want to try it yourself before deciding on a boost) here’s a breakdown of how to unlock Sea of Bygone Eras, step by step. We’ve even included some details and examples so you know exactly what you’re in for:

Once you’ve done the above you can roam the Sea of Bygone Eras freely. All teleport waypoints in the area will become available (there are many, some cleverly hidden in caves) and you can swim through the Remurian ruins. If this sounds like a lot of work – well, it is a decent evening’s worth of questing. You can do it solo or remember expert Genshin boosters from ChaosBoost can do it for you as part of the boosting service. Either way after unlocking the fun (and exploration) begins!
