The underwater ruins are much more readily accessible if you have a ship, but it is not strictly required. You can always get to them on another Adventurer's ship.
Despite their distant location, the bountiful rewards that can be obtained within them make a visit to them an entertaining journey for many.

There is quite a gap between the difficulty levels in Protty Cave and Sycraia Underwater Ruins, and between the upper and abyssal zones of the latter, so choose your path carefully.
Adventurers who have just transitioned to Succession / Awakening should visit Protty Cave first, while veteran Adventurers who are Lv. 58 and above and possessing good gear are recommended to try Sycraia Underwater Ruins.

Go to the location marked on the world map, then you need to dive underwater to find the entrance.
There are four entrances to the Sycraia Underwater Ruins: North, South, East, and West.
If you are having a hard time finding an entrance, do not forget to come back up for air before continuing your search.
Also note that if you try to enter the ruins through any other way than these four entrances, you will be blocked by a force field.

You can recover stamina by pressing "F" while floating above the water.
Of course, the preferred way of reaching this location would be by ship, as you will be able to simply return to the ship and recover if you start to run low on stamina or breath.

1. Monster Types and Level

1) Basic Information
• Mostly Lv. 60 ~ 62 monsters
• Melee: Damaged Kureba, Damaged Lykin, Damaged Pirash
 
2) Features
There is a huge amount of damaged pirash in the upper zone. You need to be careful of them, as you will pull a large group by just hitting one of them.
Damaged lykins and damaged kurebas sometimes use their powerful attacks to knock Adventurers down. Adventurers may need to dodge their attacks to stay out of trouble.
Tons of these monsters are clumped together so you can dish out punishment en masse!

You will not be able to bring a horse to carry your items, so more careful item management may be necessary.

2. Level/Equipment Requirements

If you are fully decked out in boss gear and have decent accessories, you should have no problem demolishing the monsters here.
However, there are a few inconveniences that exist as it is located offshore. That is a major reason why Adventurers tend not to crowd here too much.
That also means that you can have a great time plowing through monsters here as it is unlikely for you to bump into many other people during your time here.

3. Strategies

1) Precautions
Always be careful of damaged pirashes. Hitting one of them will immediately aggro any others nearby.
Damaged lykins and damaged kurebas sometimes use powerful attacks. They telegraph these attacks, so it is best to recognize this early and react to them before they destroy you.

2) Key Locations and Route
This monster zone is fairly wide, so try coming up with your own efficient route.

Additionally, you cannot see where you are on the world map, so you will need to use the objects in the surrounding area to navigate. Just keep at it till you memorize an easy route to follow.

Be sure to be well prepared before heading out here, as you will be very far from shore.

5. User Density

This monster zone is a treasure trove of items, including Abyssal Essence (used to make Frenzy Draught), the powerful Tungrad Ring, the combinable materials Ancient Seal - Red Shard & Black Shard (used to make the Tungrad Ring), Ancient Creature's Scale (used to release Sycrid from its seal), and more.

However, the monsters that drop this valuable loot are formidable. You will not only need high AP, but high DP as well to withstand their beating.

1. Monster Types and Level

1) Basic Information
• Mostly Lv. 65 ~ 66 monsters
• Melee: Elmermol, Kureba, Lykin, Pirash
• Others: Force Field Defender, Eyes of the Deep Sea, Tower of Restoration

2) Features
If you are used to the Hystria Ruins of Valencia, think of this monster zone as the next step in your adventures in ancient ruins.
If the force field defenders, eyes of the deep sea, and towers of restoration are left to their own devices, you may not survive the fight. Be sure to take them out first.

The area is large enough that even if you see another Adventurer here, you should be able to go on your own route without much trouble.

You will need to stay on high alert the whole time you are here, so defeating monsters for a prolonged amount of time may be difficult.

2. Level/Equipment Requirements

As was mentioned before, this monster zone is harder than the Hystria Ruins of Valencia.
We are providing guidelines for how much AP and DP you will need, but the most important factor is your skill and concentration.
If you find this place too difficult to tackle on your own, ask a friend or other Adventurers in chat to form a party with you.

3. Strategies

1) Precautions
This place may be difficult for a single person to go on their own. As it is a hard monster zone, you may want to group together with other like-minded Adventurers.
It is recommended for you to go as a party, but you can try it out solo once you are used to the area.

You can never let your guard down, especially at night when the monsters grow stronger.
Despite all this, the allure of the expensive loot is sure to keep top-tier Adventurers coming back.
 
2) Key Locations and Route
Like in the upper zone, you will also not be able to find your location on the world map during your time here. You will need to familiarize yourself with the surrounding elements and make your own route.

Note that you can enter different caves that are separated by water. Explore the whole place to find your own spot.

5. User Density

Tungrad Ring, Ancient Power - Red Shard & Black Shard, Ancient Creature's Scale, and other drops from here are sold at high prices on the Central Market.
However, that goes without saying, this place is a challenge even for the best out there.
Many will die at the hands of the ancient weapons if they lose their focus for even one moment.

Still, if you feel like you are ready for the challenge and want to try getting these great items, then dive in to find the abyssal zone of Sycraia Underwater Ruins.
