What is the Giants’ Foundry?
The Giants’ Foundry is a Smithing minigame in Old School RuneScape, released in 2022. Located in the giant city of Arposandra, players assist Kovac, a giant smith, in forging massive swords for his kin. This minigame provides a more engaging and often more cost-effective alternative to traditional Smithing training methods like making platebodies at an anvil. Instead of just clicking on an anvil, you are actively managing the temperature and refinement of a giant preform using various workshop tools. The goal is to match the specifications of a commission given by Kovac, which earns you Smithing XP, Foundry Reputation, and coins.
Giants’ Foundry Calculator Formula and Explanation
The core of this giants foundry calculator is determining the time it takes to complete one sword, which then allows us to extrapolate hourly rates for XP and points. The calculation depends on a few key variables.
The basic logic is:
Time per Sword = (Actions Required per Sword) * (Time per Action)
From there, we can determine swords per hour, and by extension, the XP and points gained. The number of actions required depends heavily on the quality of the metal alloy used.
Variables Table
| Variable | Meaning | Unit / Type | Typical Range |
|---|---|---|---|
| Alloy Type | The combination of metal bars used to create the sword preform. Better alloys have higher “Metal Scores.” | Categorical | Bronze to Adamantite/Runite |
| Metal Score | A hidden value representing the quality of the alloy. Higher scores mean fewer actions are needed per sword. | Numeric | 10 – 130 |
| Actions per Sword | The total number of refinement steps (hammering, grinding, polishing) needed to finish a sword. | Numeric | ~80 – ~150 |
| Smith’s Outfit | A reward from the minigame that speeds up actions. | Boolean / Categorical | Owned / Not Owned |
Practical Examples
Understanding the impact of your choices is key. Here are two common scenarios:
Example 1: Mid-Level Player (Level 70)
A player with 70 Smithing decides to use a Mithril/Adamantite alloy, which is a popular and efficient choice. They own the full Smith’s outfit.
- Inputs: Alloy = Mithril/Adamantite, Level = 70, Outfit = Full Set.
- Results: This player can expect approximately 12-13 swords per hour, yielding around 195,000 Smithing XP/hr and a solid amount of reputation points. This is a great balance between cost and experience gain. For a better understanding of OSRS smithing, you might want to see a full smithing guide.
Example 2: High-Level Player (Level 85+)
A player with 85 Smithing aiming for the best possible rates uses a premium Adamantite/Runite alloy.
- Inputs: Alloy = Adamantite/Runite, Level = 85, Outfit = Full Set.
- Results: This setup pushes the boundaries of efficiency, resulting in roughly 14-15 swords per hour. The XP rates can soar to 250,000-270,000 XP/hr. While more expensive, this method is one of the fastest ways to train Smithing in the game.
How to Use This Giants’ Foundry Calculator
Using this calculator is straightforward. Follow these steps for an accurate estimation:
- Select Your Alloy: Choose the combination of bars you plan to use from the dropdown menu. The 14/14 combinations are generally recommended for the best results.
- Enter Your Smithing Level: Type your current Smithing level into the corresponding field.
- Set Your Outfit Bonus: Select whether you have no outfit, a partial set, or the full Smith’s outfit. The full set provides a roughly 10% speed increase.
- Click “Calculate”: The tool will instantly compute your estimated hourly rates and display them in the results section.
- Review the Results: The calculator shows your swords per hour, points per hour, and total Smithing XP per hour, along with a chart and table for a detailed breakdown.
Key Factors That Affect Giants’ Foundry Results
- Alloy Choice: This is the single most important factor. High-tier alloys like Adamantite/Runite have a higher base “metal score,” which significantly reduces the number of actions needed to complete a sword, thus increasing XP and points per hour.
- Smithing Level: A higher Smithing level slightly increases the quality you add with each action, leading to faster sword completion and more XP.
- Smith’s Outfit: The full outfit provides a 10% increase in action speed, directly translating to more swords and XP per hour. It is a crucial upgrade.
- Player Efficiency: Minimizing mistakes, such as overheating or overcooling the preform, is vital. Each mistake requires correction, adding time to each sword.
- Mould Selection: As you earn reputation, you can buy new moulds. Using the optimal moulds for each commission provides a small but noticeable boost to quality and points earned.
- Commission Quality: The “difficulty” of the commission assigned by Kovac (e.g., “Narrow, Spiked”) sets the total quality target. More complex swords take longer but yield more points and XP. For anyone interested in other game activities, check out these osrs minigame rewards.
Frequently Asked Questions (FAQ)
What are the best bars for Giants’ Foundry?
For the best balance of XP and cost, 14 Mithril and 14 Adamantite bars are very popular. For maximum XP rates at high levels (85+), 14 Adamantite and 14 Runite bars are the best.
Is Giants’ Foundry profitable?
Yes, it can be. The coins awarded for each sword often cover, and can exceed, the cost of the bars used, especially if you use efficient bar combinations like steel and mithril. It’s considered a great osrs money making guide for mid-level players.
How much XP does Giants’ Foundry give?
XP rates can range from ~150,000/hr with mid-tier set-ups to over 270,000/hr with high-tier alloys and maximum efficiency.
How do I get a new commission from Kovac?
Simply talk to Kovac after you hand in a completed sword. He will immediately offer you a new commission to start the process over again.
Do I need Ice Gloves?
Ice Gloves (or the Smith’s gloves) are required to handle the preform when it is hot. Without them, you cannot pick up the sword from the mould-jig to begin working on it.
What is the point of buying new moulds?
Buying the mould sets from the rewards shop allows you to more closely match Kovac’s commission. A better mould match results in higher quality, which means more XP and reputation points per sword.
Can I use metal items instead of bars?
Yes, the crucible accepts many smithable metal items (like platebodies and shields). This can be a great way for ironmen to make use of monster drops.
Can this giants foundry calculator predict my exact rewards?
This calculator provides a very close estimate based on established formulas and data. However, actual results can vary slightly due to random factors in the minigame and individual player skill.
