The Frigate is one of the most powerful endgame ships in Skull and Bones, but unlocking its full potential requires a significant investment of time and resources. From acquiring the initial blueprint to gathering hundreds of upgrade materials, captains should prepare for a lengthy grind before reaching the maximum ship level.
This guide covers every material needed to build the Frigate, where to farm them efficiently, and the best strategies to speed up the upgrade process.
Frigate Build Requirements
Before you can construct the Frigate, you’ll first need to unlock its blueprint through the Smuggler’s Pass tier milestones. Once obtained, gather the following materials:
| Material | Quantity |
| Planetary Gearset | 8 |
| Worm Drive | 10 |
| Deep Iron | 6 |
| Precision Drilling Bit | 6 |
| Torsion Spring | 2 |
| Orca Intricate Apparatus | 2 |
| Gannet Dense Niter | 12,000 |
These materials represent only the initial construction costs. The real investment begins when upgrading the ship through its later levels.
Frigate Upgrade Costs
Reaching Level 15 demands a large amount of endgame resources.
One of the biggest bottlenecks is Deep Iron. Since five pieces of Deep Iron must be refined into a single Deep Iron Plate, players typically need around 250 Deep Iron throughout the complete upgrade process.
Alongside Deep Iron, you’ll also consume numerous advanced manufactured components crafted from refinery materials or obtained from high-level combat activities.
Best Ways to Farm Deep Iron
Deep Iron remains the most sought-after upgrade resource for Frigate owners. Fortunately, there are several reliable farming methods.
1. Plunder Mega Forts
The most efficient farming route is repeatedly attacking Mega Forts, especially locations such as Fort Wolvin Hole.
Typical rewards include:
- Around 5 Deep Iron per successful plunder
- Average completion time of 10–15 minutes
- Consistent endgame loot suitable for ship progression
Running Mega Forts with a coordinated crew can significantly improve farming efficiency.
2. Purchase from Vendors
If you have accumulated the required currencies, limited quantities of Deep Iron can be purchased from merchants including:
- Blackwood
- Tlock
- Yanita
Some purchases require Moonshiner currency, making vendor stock a useful supplement rather than a primary source.
Farming Rare Manufactured Parts
Several Frigate upgrades require advanced crafted components built from refinery materials.
Important examples include:
- Orca Mechanisms
- Saltpeter-based components
- Other refined endgame materials
Although refinery production takes time, many higher-tier materials also drop from Elite Warships.
Best Elite Warship Targets
Players farming rare parts should prioritize encounters such as:
- Fangs of the Far
- Treacherous Turn
These enemies on World Tier 2 frequently reward valuable upgrade materials that reduce crafting time and resource costs.
Recommended Farming Priority
Instead of collecting materials randomly, focus on the biggest bottlenecks first.
| Priority | Material | Recommended Source |
| 1 | Deep Iron | Mega Fort plunders |
| 2 | Rare Orca Components | Elite Warships |
| 3 | Gannet Materials | Elite Warships and Refinery |
| 4 | Refinery Components | Passive crafting |
| 5 | Vendor Purchases | Blackwood, Tlock, Yanita |
Following this order helps prevent situations where one missing material delays multiple upgrades.
Tips to Reach Frigate Level 15 Faster
To maximize your farming efficiency:
- Prioritize Mega Fort runs whenever available.
- Queue refinery jobs before logging off to minimize downtime.
- Farm Elite Warships while refinery timers are active.
- Save Moonshiner currency for purchasing scarce Deep Iron when vendor inventories refresh.
- Join groups for faster fort clears and more consistent endgame farming.
Planning your farming sessions around these activities can dramatically shorten the overall upgrade timeline.
Is the Frigate Worth the Grind?
For players focused on endgame PvE and large-scale naval combat, the Frigate is one of the strongest long-term investments available. While the resource requirements are substantial, the ship’s combat capabilities and durability make it well worth the effort for dedicated captains.
If you’re looking to accelerate your progression even further, many players also choose to obtain Skull and Bones Items or Buy SNB Silver to reduce the time spent farming and focus more on enjoying high-level content.
Whether you prefer gathering everything yourself or supplementing your progression with additional resources, careful planning is the key to maximizing your efficiency.
