Giants Foundry Moulds in OSRS: A Complete Guide to Optimizing Your Smithing
Old School RuneScape (OSRS) offers players a variety of ways to train skills, and the Giants’ Foundry minigame stands out as a unique and engaging method for leveling up Smithing. Introduced on June 8, 2022, after the completion of the Sleeping Giants quest, this minigame tasks players with crafting massive swords for Kovac, a friendly giant. Central to this process are the moulds, which determine the quality and efficiency of the swords you produce. In this blog post, we’ll dive deep into everything you need to know about Giants’ Foundry moulds in OSRS, from how they work to the best strategies for unlocking and using them effectively.
Moulds in the Giants’ Foundry are templates used to shape the molten metal into swords that meet Kovac’s commission requirements. Each commission comes with two attributes (e.g., “Narrow” and “Spiked”), and selecting the right mould is key to maximizing the sword’s quality, which in turn affects your Smithing experience, gold rewards, and Foundry Reputation.
How Moulds Impact Sword Quality
The quality of a sword is determined by two main factors: the metal score (based on the bars or items you use) and the mould score (based on how well your chosen mould matches the commission). A higher mould score means better rewards, making mould selection a critical part of the minigame.
Default vs. Purchasable Moulds
Players start with a set of default moulds, but additional moulds can be purchased from Kovac’s reward shop using Foundry Reputation. These purchasable moulds often provide higher scores and better alignment with specific commission types, significantly boosting your efficiency as you progress.
Understanding the Mould Library
The Mould Library is the interface where you select your moulds before pouring the metal. It’s divided into three parts—Forte, Tip, and Base—each contributing to the overall mould score. Your goal is to pick a combination that best matches Kovac’s requested attributes.
Forte Moulds
Forte moulds shape the sword’s handle and influence attributes like “Heavy” or “Light.” Examples include the default Chopper Forte and the purchasable Juggernaut Forte.
Tip Moulds
Tip moulds define the sword’s point, affecting attributes like “Spiked” or “Flat.” The default Spike Tip is a starting option, while options like Serrated Tip can be unlocked later.
Base Moulds
Base moulds determine the sword’s foundation, contributing to attributes like “Broad” or “Narrow.” The Defender Base is available by default, with upgrades like Fleur-de-lis Base available for purchase.
List of Giants Foundry Moulds
Here’s a breakdown of the moulds available in the Giants’ Foundry, including their requirements and costs. Note that purchasing all moulds costs 5,400 Foundry Reputation in total.
Default Moulds
- Chopper Forte: +1 Heavy, +1 Light
- Spike Tip: +1 Spiked, +1 Flat
- Defender Base: +1 Broad, +1 Narrow
These moulds are unlocked from the start and provide an average mould score of 38 when optimally combined.
Purchasable Moulds
| Mould Name | Type | Attributes | Smithing Level | Reputation Cost |
|---|---|---|---|---|
| Choppa! | Forte | +5 Heavy | 30 | 300 |
| Spiker! | Tip | +5 Spiked | 40 | 400 |
| The Point! | Tip | +5 Flat | 50 | 500 |
| Needle Point | Tip | +5 Narrow | 60 | 600 |
| Fleur-de-Blade | Base | +5 Broad | 70 | 700 |
| Juggernaut Forte | Forte | +5 Light | 79 | 900 |
| Serrated Tip | Tip | +5 Heavy | 60 | 600 |
| Corrupted Point | Tip | +5 Broad | 40 | 300 |
Using optimal purchased moulds raises the average mould score to 59, significantly improving your rewards.
Strategies for Optimizing Mould Selection
Choosing the right moulds can make or break your Giants’ Foundry experience. Here are some strategies to get the most out of your moulds.
Prioritize High-Value Moulds Early
Focus on unlocking moulds like Choppa!, Spiker!, and The Point! as soon as possible. These provide strong attribute bonuses at relatively low Smithing levels, giving you a solid foundation for better scores.
Match Moulds to Commissions
Always check Kovac’s commission before selecting your moulds. For example, a “Heavy Spiked” commission pairs well with Choppa! and Spiker!. The closer the match, the higher your mould score.
Avoid Obsolete Moulds
Some moulds, like Juggernaut Forte (obsolete at level 79) and Corrupted Point (obsolete at level 60), become redundant once you unlock better options. Skip these if you’re close to the level where superior moulds become available.
Use Boosts Wisely
You can boost your Smithing level temporarily (e.g., with a Dwarven Stout) to purchase and use moulds above your current level. However, you must maintain the boosted level until the metal is poured, or you won’t be able to use them.
Tips for Maximizing Rewards with Moulds
Beyond mould selection, your overall approach to the Giants’ Foundry can amplify the benefits of using the right moulds. Here are some actionable tips.
Combine with the Smiths’ Uniform
The Smiths’ Uniform, purchasable from the reward shop, increases your forging speed by up to 15% when wearing the full set. Pairing this with optimal moulds maximizes your experience and reputation per hour.
Choose Cost-Effective Metals
Using a mix of Steel and Mithril bars (14/14 blend) can be profitable, especially with optimal moulds and no mistakes. This combo balances cost, experience, and reward potential.
Minimize Mistakes
Each mistake during the refinement process (e.g., using the wrong tool at the wrong temperature) deducts 5 points from your final quality score. Practice precision to preserve the benefits of high-scoring moulds.
Track Progress with RuneLite
The RuneLite plugin Easy Giants’ Foundry can help you quickly identify the best moulds for each commission, saving time and boosting efficiency.
Why Giants Foundry Moulds Matter for Smithing
The Giants’ Foundry offers a refreshing alternative to traditional Smithing methods like the Blast Furnace, which can feel repetitive and resource-intensive. Moulds are the backbone of this minigame, allowing players to tailor their experience and rewards to their skill level and goals.
Experience Rates and Rewards
With optimal moulds and high-quality swords (up to 199 quality), you can earn up to 25,230 Smithing XP per sword, plus gold rewards double that amount. At higher levels, this translates to roughly 276,000 XP per hour—competitive with top-tier methods.
A Fun and Interactive Skill Grind
Unlike the monotonous click-and-wait of anvil smithing, the Giants’ Foundry requires active engagement. Moulds add a layer of strategy, making each commission a puzzle to solve rather than a mindless task.
Long-Term Benefits
Unlocking moulds and mastering the minigame not only boosts your Smithing level but also provides access to rewards like the Double Ammo Mould and Smithing Catalyst, which enhance other aspects of OSRS gameplay.
In conclusion, Giants’ Foundry moulds are a game-changer for OSRS players looking to level up Smithing in a fun, rewarding way. By understanding the mould system, prioritizing key purchases, and refining your strategy, you can turn this minigame into a powerhouse for experience, gold, and reputation. Whether you’re a low-level adventurer or a seasoned smith, the right moulds will set you on the path to success. So grab your bars, head to the Foundry, and start forging—Kovac’s waiting!
