I surfaced off a rusted pier, lungs burning, watching a shark slip under the waves. The ocean below was a locked library, every sunken corridor asking for a key. You need the right suit to read those shelves — and I learned where to get it.
I’ve sifted through pre-order notes, Steam threads, and a few dusty forum posts so you don’t have to. Below I’ll walk you through the two practical ways to get a diving suit, how long it actually buys you underwater time, and the small upgrades that turn a nervous dip into a calm swim. Read slowly or skim the steps — either way, you’ll be able to probe the Great Ocean of Pywel with confidence.
At the pre-order counter, a shiny package hides useful gear — How to Get the Charter’s Diving Set in Crimson Desert
If you claimed the Crimson Desert: Charting the Unknown pre-order, the Charter’s Diving Set is part of that bonus. Here’s the fastest route to equipping it so you can stop gasping and start exploring.
- Launch Crimson Desert on Steam, PlayStation, or Xbox and open the pause menu.
- Go to Others and select Add-ons.
- Claim the Charter’s Diving Set for Kliff and Oongka and the Charter’s Light Diving Set for Damiane from the listed pre-order items.
- Equip the helm and suit in your inventory. The helm + suit together add +120 max breathing, which converts to roughly 4 minutes of continuous underwater time. The gloves and boots each add a +2% Swim Speed Multiplier, for about 4% total swim speed when fully kitted.
How do I get a diving suit in Crimson Desert?
There are two clear paths: claim the pre-order Charter’s set if you purchased the DLC early, or buy the standard Marine Charter’s suit from Sulivan’s Relic Exchange at Demeniss port. I tested both — pre-order gear is simply better for raw breathing time, while the purchasable set is perfectly serviceable if you missed the pre-order window.
At a cluttered stall in Demeniss, relics sit behind glass — How to Buy Diving Suit in Crimson Desert
If you missed the pre-order window, Pearl Abyss didn’t lock all underwater play behind a paywall. Sulivan’s Relic Exchange sells a practical Marine Charter’s Diving set for in-game currency: Shattered Ancient Relics.
- Fast-travel or sail to Demeniss Port.
- Find Sullivan’s Relic Exchange (this is not the ship shop NPC).
- Select Buy and purchase the Marine Charter’s Diving Helm, Suit, Gloves, and Boots (or the Light variants for Damiane) using Shattered Ancient Relics.
Remember: the Marine Charter’s Diving suit raises max breathing by +60, giving you about 2 minutes under water — enough for many wrecks and chests, but not for long corridors.
Here’s the list Sulivan sells, with costs in Shattered Ancient Relics:
| Diving Item | Cost (Shattered Ancient Relics) |
|---|---|
| Marine Charter’s Diving Helm | 5 |
| Marine Charter’s Diving Suit | 7 |
| Marine Charter’s Diving Gloves | 5 |
| Marine Charter’s Diving Boots | 5 |
| Marine Charter’s Light Diving Helm | 5 |
| Marine Charter’s Light Diving Suit | 7 |
| Marine Charter’s Light Diving Gloves | 5 |
| Marine Charter’s Light Diving Boots | 5 |
Can I swim underwater without a diving suit?
Yes — but not for long. Without a suit you’ll only last seconds to a minute or two. The suit adds measurable breathing time and comfort; in my playtests the +60 suit got me through a quick wreck run, while the +120 pre-order setup made long corridor exploration possible.
On the surface, one button flips the world upside down — How to Swim Underwater in Crimson Desert
Swimming is immediate and simple: press the Dive button once while in the sea. But there are sensible upgrades you should track down if you want longer sessions beneath the waves.
- Equip a diving suit first. Either Charter’s Diving Set (+120 breathing) or Marine Charter’s Diving Set (+60 breathing) will be worn from inventory and used automatically when you enter the water.
- Propulsion Breathing Device: found in a chest in the Dead Coral Sea, it adds +600 breathing.
- Enhanced Propulsion Breathing Device: blueprint sits in an underwater pyramid in the South Sea; when crafted it gives +900 breathing.
- Ocean Drifter mount: discovered in a South Sea chest; it boosts underwater speed and makes long passages less tedious.

I’ve tested routes on Steam and checked forum reports on Reddit and YouTube to confirm locations and chest spawns; Pearl Abyss’s in-game text matches the map markers. Treat the Propulsion devices like breathing extensions — the suit becomes a second heartbeat when you’re mapping underwater caverns. Which approach did you try first, and which find was most worth the risk?
