Oxygen management is critical in Abyss Roblox. The deeper you dive, the faster your oxygen depletes, and running out means drowning—which costs you 25% of your catch and some cash. Fortunately, several reliable methods exist to refill your oxygen tank before it runs dry.
Quick answer: Return to safe areas like the Forgotten Dome, use Oxygen Pods from your inventory, purchase pods from Crazy Jeff's Store in Ancient Sands, or complete quests that reward pods.

Return to Safe Areas for Full Refills
The simplest way to refill your oxygen completely is to return to designated safe zones. The Forgotten Dome, where The Kraken resides, automatically restores your oxygen to maximum capacity the moment you step inside. Other safe areas scattered across the map provide the same instant refill effect.
This method works best when you're planning a return trip to the surface or need to reset before a long dive. No items are consumed, and the refill is instantaneous.
Use Oxygen Pods from Your Inventory
Oxygen Pods are consumable items that restore oxygen instantly while underwater. You can carry multiple pods and use them on demand by opening your inventory and selecting the pod. Each pod type restores a fixed amount of oxygen:
- Small Oxygen Pod (Common): Restores 25 oxygen
- Basic Oxygen Pod (Uncommon): Restores 50 oxygen
- Advanced Oxygen Pod (Rare): Restores 100 oxygen
- Heavy Oxygen Pod (Epic): Restores 250 oxygen
Pods are essential for extended exploration. Keep a supply in your inventory before venturing into deep zones where safe areas are sparse.

Obtain Oxygen Pods from Quests
Completing quests given by NPCs frequently rewards you with Oxygen Pods. The difficulty of the quest typically determines the quality of the pod you receive. Harder quests yield rarer pods with higher oxygen restoration values.
Quest rewards stack over time, so consistently finishing tasks builds a reliable pod reserve. This method requires no currency and integrates naturally with progression.
Find Oxygen Pods in Treasure Chests
Treasure chests are hidden throughout the map and contain Oxygen Pods along with other materials. Opening chests also contributes to badge progress, including the Treasure Hunter Abyssborn badge.
Chests come in two rarities. Common chests have a 10% chance to drop one pod, while Rare chests guarantee at least one pod and may include multiple. Exploring thoroughly increases your pod stockpile without spending money.
Purchase Oxygen Pods from Crazy Jeff's Store
Crazy Jeff's Store is located in the Ancient Sands area. The shop sells Advanced Oxygen Pods for $550 each. After purchasing, the store restocks every three minutes, allowing you to buy additional pods if you have the currency and time to wait.
This method is useful when you need pods immediately and have cash available. The Advanced Oxygen Pod restores 100 oxygen, making it a solid mid-tier option for extended dives.

Redeem Abyss Codes for Oxygen Pods
Active codes occasionally provide Oxygen Pods as rewards. Redeeming codes is free and requires no in-game progress. Check for new codes regularly to supplement your pod supply without spending currency or completing quests.
Upgrade Your Tube for Better Oxygen Capacity
While not a direct refill method, upgrading your Tube increases your maximum oxygen capacity. A larger tank means you can stay underwater longer before needing to refill. Better Tubes are available through progression and provide a permanent improvement to your oxygen management.
Combining a high-capacity Tube with a steady supply of Oxygen Pods gives you the flexibility to explore deep zones without frequent surface trips.

What Happens if You Run Out of Oxygen
If your oxygen depletes completely, you drown. The game respawns you at your base, but you lose 25% of your current catch and some cash. This penalty makes oxygen management essential, especially when carrying valuable or rare fish.
The game does not feature permadeath. You can retry immediately after drowning, but repeated deaths add up in lost progress and currency.
Maintaining a full oxygen tank requires planning. Stock up on Oxygen Pods before deep dives, complete quests for free pods, and upgrade your Tube as soon as possible. Safe areas provide instant refills when you're near the surface, but pods are your lifeline in the deep ocean. Keep your reserves high, and you'll avoid the costly penalty of drowning.
