Better Diving Mod — Guide
Diving Gear
Diving gear is split into three tiers: Standard, Improved, and Reinforced. While Standard gear provides basic utility, Improved gear offers specialized perks, and Reinforced gear provides maximum armor protection.
| Item | Tier | Primary Benefit |
|---|---|---|
| Diving Mask | Standard | Required to use Oxygen Tanks. |
| Rebreather | Improved | Recycles CO2; removes the oxygen penalty at depths below 30 blocks. |
| Reinforced Mask | Reinforced | Provides high armor while maintaining mask functionality. |
| Standard O2 Tank | Standard | Adds +90 seconds of oxygen capacity. |
| High Capacity Tank | Improved | Adds +135 seconds of oxygen capacity. |
| Ultra High Capacity | Improved | Adds +225 seconds of oxygen capacity. |
| Wetsuit Leggings | Standard | Increases underwater mining speed. |
| Fins | Standard | Increases swim speed. |
| Ultra Glide Fins | Improved | Significantly increases swim speed beyond standard fins. |
Note: Oxygen tanks slightly decrease your swim speed due to their weight, which can be offset by high-tier fins.
Vehicles
For advanced exploration, the mod adds two primary modes of transport:
Seaglide
A handheld propulsion tool that significantly increases swim speed while held. It consumes energy from a battery and features a built-in light for navigating dark trenches.
Seamoth
A modular, one-person submersible. It allows for high-speed travel and provides a constant supply of oxygen to the pilot.
- Power: Requires a Power Cell to operate.
- Modules: The Seamoth can be customized with up to four upgrade modules:
- Depth Modules (MK1-MK3): Increases the safe diving depth before the hull takes pressure damage.
- Storage Module: Adds a small inventory to the exterior of the sub.
- Solar Charger: Recharges the Power Cell when the sub is near the surface during the day.
- Sonar: Sends out a pulse to highlight the surrounding terrain and entities.
- Perimeter Defense: Discharges an electrical pulse to ward off aggressive mobs.

World Generation & Resources
Better Diving adds new flora and mineral outcrops to the ocean floor to facilitate its unique crafting progression.
Outcrops
Instead of traditional ores, players find "Outcrops" that must be broken to reveal resources: * Limestone Outcrop: Drops Titanium or Copper Ore. * Sandstone Outcrop: Drops Silver Ore, Lead, or Gold. * Shale Outcrop: Drops Redstone, Gold, or Diamonds.
Flora
- Creepvine: Tall, glowing kelp. Breaking the vine yields Creepvine Samples (used for Fiber Mesh). Right-clicking the glowing pods yields Creepvine Seed Clusters (used for Silicone Rubber).
- Acid Mushroom: Found in clusters on the seabed. Used as a primary component in crafting Batteries.
