This covers only the weapons added in Charting the Unknown whose locations have been confirmed. Most require a shovel and a diving suit, and the island names on the map are translated names, so you'll need to match them in-game yourself.
Required prep: Shovel, diving suit (spare breath), ship
Lumen Two-Handed Sword: Garden of Trials reward
Lumen One-Handed Sword: Chest in the underwater ruins south of Karkano Island
Void Longsword: Hidden cave in the Trivana Strait, Crimson Desert region
As of: November 7
What to Prepare First
Shovel: Required to dig up buried chests.
Diving suit: Deep-sea chests need plenty of breath, so bring breathing gear.
Ship and shark mount: Greatly helps with travel between islands and dive speed.
Kliff, Oongka, and Damian can all use longswords and spears, while one-handed swords can only be used by Kliff and Oongka. The rapier (translated name) is exclusive to Damian.
Lumen One-Handed Sword — Underwater South of Karkano Island
Use the Abyss Nexus on Karkano Island.
Sail southeast, pass a small unnamed island, then head south again and anchor near the underwater ruins.
Dive to the east and look for the cave entrance in the west-facing cliff wall.
Follow the tunnel in and get the Lumen One-Handed Sword (base attack 18, max 51) from the chest on the top floor.
Lumen Two-Handed Sword — Garden of Trials
A top-rarity longsword placed on the central dais of the Garden of Trials, with base attack 24 and max 64, the highest of the DLC weapons. After clearing "End of the Journey," enter the new passage at the Axiom Archive and beat all challenges (3 bosses per group, and no food healing inside) to receive it in a new area of the hub. It comes with unique effects such as level 2 vitality absorption and 2 empty Abyss Gear slots.
3 Buried Chests You Dig Up With a Shovel
Silverwave Longsword (translated name, max 39): Comes from a buried chest at a spot north of the east coast of Navra Island. A longsword whose attack speed rises from level 2 to level 3.
Spiral Spear (translated name, max 36): A buried chest east of Ocula Island in the southeast sea. It has a 2% stamina cost reduction, and Swift 2, Destruction 1, and Insight 1 come pre-equipped.
Abyssal Fang (translated name, max 35): A buried chest on Scion Island. It comes with critical chance level 3.
Void Longsword and Satyr Spear
Void Longsword (max 38): A hidden cave in the Trivana Strait, Crimson Desert region. Pass through the illusion wall south of the cliff, follow the buried passage, and pull the lever on the left to open the boss room. You get it by defeating the Void Knight, and the chest in the same room has the Void Plate armor.
Satyr Spear (max 35, usable by all three characters): Defeat the satyr who has taken over the waterfall village on the southern island among the islands at the far southwest of the ocean, and you will pick it up along with 5 relics and an Abyss Artifact. Its 5 Abyss Gear slots come pre-filled with Attack 1, Attack Speed 1, and Thorn of Eclipse.
Weapons Whose Locations Couldn't Be Confirmed
Gatekeeper's Longsword, Beast Claw, Harpoon Spear, Black Wave Spear, Black Fang Sword, Priest's Ritual Sword, Silver Shatter Mace, Deepbinder's Rapier (Damian-exclusive), and Harpoon Gun: this research couldn't confirm where to get them (all translated names). We will follow up as soon as they are confirmed.
💡 Tip: You have to dig up buried chests with the shovel equipped, standing on the map marker. If a chest won't open, the position may be slightly off, so look around once.
⚠ Weapon and island names are translations of English guides (Navra Island is split between Navra and Navrah depending on the source). In one overseas guide, some effect values differ between the body text and the table, so only certain effects are listed. Values are at +10 refinement.
