What is OSRS Giants’ Foundry?

The Giants’ Foundry is a unique skilling activity in Old School RuneScape (OSRS) introduced in the Quest “Secrets of the North”. It allows players to engage in a smithing minigame where they forge specialized weapons for the Dwarven Blacksmith. This activity provides a blend of smithing experience, potential profit, and a change of pace from traditional smithing methods. It’s designed to be more engaging than simply smithing bars at an anvil, offering strategic depth through customer orders and metal choices.

Anyone looking to train their Smithing level in OSRS, especially those who find the standard smithing methods tedious, should consider the Giants’ Foundry. It’s particularly beneficial for ironmen and players seeking to make some gold while training. The activity is accessible after completing “Secrets of the North”, making it available relatively early in a player’s journey, though higher Smithing levels are required to forge the most valuable metals.

A common misconception is that the Giants’ Foundry is solely a gold-making venture. While it can be profitable, its primary purpose is a faster and more engaging way to gain Smithing experience. Another misunderstanding is that any metal can be used for any order; players must match the metal type requested by the customer to maximize points and rewards. Ignoring the customer’s preferred metal type significantly reduces the potential gains.

Giants’ Foundry Formula and Mathematical Explanation

The core of the Giants’ Foundry lies in converting the bars you forge into points, and then those points into experience and gold. The efficiency and profitability depend on several interconnected factors.

Points Calculation

The points awarded per bar depend on the chosen metal type, the strikes per bar you achieve, and the customer satisfaction level.

Points Per Bar = (Base Points for Metal + Customer Satisfaction Bonus) * (Strikes Per Bar / 100)

The Customer Satisfaction Bonus is applied as follows:

• Poor (0): +0 points
• Fair (1): +5 points
• Good (2): +15 points
• Excellent (3): +30 points
• Perfect (4): +50 points

For example, forging a Dragon bar with 100 strikes for a “Perfect” customer would yield: (70 + 50) * (100 / 100) = 120 points per bar.

Experience Calculation

Experience is gained per bar forged, with a bonus based on the number of strikes.

Experience Per Bar = Base XP for Metal + (Strikes Per Bar * XP per Strike)

For Dragon bars, with 100 strikes: 112 + (100 * 2.8) = 392 XP per bar.

Profit Calculation

Profit is determined by the gold value of the points earned minus the cost of the bars used. The conversion rate from points to GP is an approximation, generally around 14 GP per point for Bronze, increasing linearly with metal tier.

Total Points Earned = Points Per Bar * Number of Bars Forged
Gold Value of Points = Total Points Earned * Points to GP Rate
Cost of Bars = Number of Bars Forged * Cost Per Bar
Total Profit = Gold Value of Points - Cost of Bars

Profit Per Bar = Total Profit / Number of Bars Forged
Profit Per Strike = Total Profit / (Number of Bars Forged * Strikes Per Bar)

Time and Efficiency

The time taken per batch (28 bars) is crucial for calculating hourly rates. A full batch typically takes around 5 minutes (including setup and smithing time). Assuming 3 batches per hour:

XP Per Hour = Experience Per Bar * Bars Per Furnace * (3600 / Time Per Batch in Seconds)
Profit Per Hour = Total Profit * (3600 / Time Per Batch in Seconds)

Practical Examples (Real-World Use Cases)

Example 1: Maximizing Experience with Adamant Bars

A player wants to train Smithing efficiently using Adamant bars. They have access to Adamant bars costing 1800 GP each on the Grand Exchange. They aim for high strikes and excellent customer satisfaction.

• Metal Type: Adamant
• Bars Per Furnace: 28
• Strikes Per Bar: 100
• Customer Satisfaction: Excellent (Bonus +30)
• Cost Per Bar: 1800 GP

Calculations:

• Base Points (Adamant): 50
• Points Per Bar = (50 + 30) * (100 / 100) = 80 Points
• Experience Per Bar = 80 + (100 * 2.0) = 280 XP
• Total Points for Batch = 80 * 28 = 2240 Points
• Estimated GP Value of Points (Rate for Adamant is ~70): 2240 * 70 = 156,800 GP
• Cost of Bars = 28 * 1800 = 50,400 GP
• Total Profit = 156,800 – 50,400 = 106,400 GP
• Profit Per Bar = 106,400 / 28 = 3,800 GP
• XP Per Hour (assuming 3 batches/hour): 280 * 3 = 840 XP/Hour
• Profit Per Hour (assuming 3 batches/hour): 106,400 * 3 = 319,200 GP/Hour

Interpretation: Using Adamant bars with high satisfaction and full strikes provides excellent profit and good experience rates. The player gains over 300k GP per hour while training Smithing.

Example 2: Balancing Profit and XP with Mithril Bars

Another player is using cheaper Mithril bars (1000 GP each) and achieves good satisfaction but not always perfect strikes.

• Metal Type: Mithril
• Bars Per Furnace: 28
• Strikes Per Bar: 75
• Customer Satisfaction: Good (Bonus +15)
• Cost Per Bar: 1000 GP

Calculations:

• Base Points (Mithril): 40
• Points Per Bar = (40 + 15) * (75 / 100) = 55 * 0.75 = 41.25 Points (rounded down in-game)
• Experience Per Bar = 64 + (75 * 1.6) = 64 + 120 = 184 XP
• Total Points for Batch = ~41 * 28 = ~1148 Points
• Estimated GP Value of Points (Rate for Mithril is ~56): ~1148 * 56 = ~64,288 GP
• Cost of Bars = 28 * 1000 = 28,000 GP
• Total Profit = ~64,288 – 28,000 = ~36,288 GP
• Profit Per Bar = ~36,288 / 28 = ~1,296 GP
• XP Per Hour (assuming 3 batches/hour): 184 * 3 = 552 XP/Hour
• Profit Per Hour (assuming 3 batches/hour): ~36,288 * 3 = ~108,864 GP/Hour

Interpretation: While the XP rates are lower than Adamant, this method still offers a decent profit margin and a viable way to train Smithing. The lower strikes reduce both points and profit per bar.

Key Factors That Affect OSRS Giants’ Foundry Results

Several elements significantly influence how much experience and profit you can achieve at the Giants’ Foundry. Understanding these factors allows for better strategy and optimization:

1. Metal Type: This is the most fundamental factor. Higher-tier metals like Rune and Dragon bars offer significantly higher base points and XP, but also come with a much higher bar cost, impacting overall profit.
2. Bar Cost (GP): The Grand Exchange price or cost to craft your bars directly impacts profit margins. A high bar cost can negate the benefits of high points unless the conversion rate is also very high. Always check current GE prices.
3. Strikes Per Bar: Achieving 100 strikes per bar maximizes the bonus points and XP. Lower strike counts reduce efficiency significantly. Practicing to achieve higher strikes is vital.
4. Customer Satisfaction: Landing “Perfect” or “Excellent” satisfaction provides substantial bonus points, directly boosting your score and subsequent GP conversion. “Poor” satisfaction yields minimal points.
5. Points to GP Conversion Rate: This rate scales with the metal tier. While higher tiers give more points, the GP conversion is what ultimately determines profit. Fluctuations in the GE prices of ores and bars can indirectly affect this perceived profitability.
6. Time Efficiency (Actions Per Hour): The speed at which you can complete batches (smithing, casting, etc.) directly influences your XP/HR and GP/HR. Minimizing downtime between batches is crucial for maximizing hourly output.
7. Smithing Level: Your Smithing level dictates which metal bars you can even forge. Higher levels unlock access to more profitable and experience-rich metals.
8. Dwarven Blacksmith’s Favor: While not a direct calculation input, maintaining high favor with the Dwarven Blacksmith can unlock useful perks and potentially increase rewards, though this is more anecdotal.

Frequently Asked Questions (FAQ)

Q: What is the best metal to use at Giants’ Foundry?

A: For maximum experience, Dragon or Runite bars are best. For profit, it depends heavily on the current Grand Exchange prices versus the Points to GP conversion rate. Adamant and Mithril often offer a good balance.

Q: How do I get 100 strikes per bar consistently?

A: This requires practice and understanding the rhythm of the minigame. Aim for the ‘Perfect’ satisfaction level, as it grants the most points and often helps achieve higher strike counts.

Q: Is Giants’ Foundry profitable for Ironmen?

A: Yes, if you gather your own ores or have a cost-effective way to obtain bars. The main “cost” is your time spent gathering resources. It’s a good alternative to standard smithing for progression.

Q: How much XP do I get per hour at Giants’ Foundry?

A: XP rates vary greatly depending on the metal used and efficiency. With Dragon bars and optimal conditions, you can achieve upwards of 40k-50k XP/HR. With lower tier bars, expect significantly less, perhaps 5k-20k XP/HR.

Q: Does the calculator account for the cost of making bars (e.g., smelting)?

A: The calculator uses ‘Cost Per Bar’ as a direct input. You should enter either the GE price or your total cost to acquire/create one bar, including smelting, if applicable.

Q: What is the “Points to GP Rate” based on?

A: This is an estimated conversion derived from observing the average profit generated at different metal tiers when achieving optimal points. It fluctuates with GE prices.

Q: Can I use different metals in the same batch?

A: No, each batch at the Giants’ Foundry uses a single type of metal bar.

Q: Is Giants’ Foundry better than Blast Furnace for profit?

A: Blast Furnace is generally more profitable for pure GP/HR, especially for high-level bars. Giants’ Foundry offers a competitive XP rate with potential for profit, and is generally less click-intensive once you get the rhythm.
