The Giant Foundry is one of the most rewarding and accessible Smithing-focused minigames in Old School RuneScape. Introduced as a fun alternative to traditional Smithing training, it offers a fresh approach that combines timing, planning, and resource management. Whether you’re aiming to break up the monotony of smelting bars or on a direct path to level 99 Smithing, the Giant Foundry is a powerful tool in your progression arsenal.

The Giant Foundry is a Smithing minigame located just west of the River Salve in Al Kharid. It tasks players with crafting massive weapons for the giant Kovac by using leftover metal items. The core loop centers around melting down unwanted bars and equipment, then carefully working that molten metal into specific weapon commissions.

This minigame is available only after completing the Sleeping Giants quest, a short and straightforward quest that introduces the mechanics of the foundry. Once completed, you’ll gain permanent access to the Foundry and unlock the ability to earn both Smithing XP and unique rewards through commissions.

At the start of every session, players receive a weapon commission from Kovac. These commissions list specific traits the final weapon should have—things like spiked, heavy, wide, or pointed. Your goal is to forge a weapon that closely matches those specifications.

The Process:

1. Select Your Materials – Withdraw bars or equipment from the bank chest and deposit them into the crucible. Your metal blend determines the quality and traits of the weapon.

2. Choose a Mold – Select the correct blade mold to match the commission traits. Molds are sorted into combinations like pointed/heavy or narrow/spiked. The closer your mold fits the commission, the higher your quality rating.

3. Forge the Weapon – Heat, cool, grind, and polish your workpiece across a series of stations. Each stage demands timing and precision—go too fast or too slow, and you’ll ruin the weapon.

4. Deliver and Repeat – Once completed, turn the weapon in to Kovac for XP and Foundry Reputation, which you can use to unlock rewards.

Efficiency Tips & Strategies

Use Cheap Bars

Steel and mithril bars hit the sweet spot for XP and cost efficiency. Avoid using high-value bars like rune unless you’re focused on maximizing hourly XP and not profit.

Maintain Heat Balance

The weapon must be kept within specific temperature ranges during processing. Always watch the temperature bar while grinding or hammering. Use water or the lava pool to adjust the temperature quickly.

Learning which molds correspond to which traits will dramatically speed up your workflow. For example:

Pointed + Spiked → Serrated mold

Narrow + Sharp → Needle mold

Bring the Right Items

Inventory should include:

Various metal bars or salvaged items to melt

Ice gloves (optional, for faster cooling)

Weight-reducing gear for faster movement between stations

Avoid Common Mistakes

Don’t ignore the trait requirements—accuracy affects your reward.

Don’t overfill the crucible; excess materials are wasted.

Monitor your progress bar—every tool stage has its ideal zone for maximum points.

Aside from being a fun and semi-AFKable training method, the Giant Foundry offers some of the most valuable rewards for Smithing and Ironman accounts alike:

Colossal Blade – A massive 2-handed sword with unique aesthetics.

Smithing Catalyst – Reduces bar cost when smelting or smithing outside the Foundry.

Moulds – Unlock more blade types to improve your weapon quality and XP rates.

Double Ammo Mould – Craft double ammo when smithing ranged weaponry (very useful for Ironmen).

The XP rates range from 120k–250k XP per hour depending on your level and material efficiency, which rivals or surpasses many conventional Smithing methods.

The Giant Foundry offers an excellent break from the grind while delivering some of the best XP per GP in the game. For Ironman players, it’s a dream come true—efficient, bar-conserving Smithing that doesn’t rely on costly resources.

Plus, the gameplay loop is satisfying: forge, heat, cool, perfect your weapon, and get paid. It’s also a great place to socialize, as the Foundry is a hotspot for both casual and hardcore Smithing trainers.

The Giant Foundry is more than just another minigame—it’s a game-changer for OSRS Smithing. It offers excellent XP, fun and dynamic gameplay, and valuable rewards with no risk of death or PvP interference. Whether you’re training for profit, XP, or just to experience something new, this content is well worth your time.

And if you’re ever low on bars or short on supplies, RuneScape gold for sale like RSgoldfast can help keep your anvil burning hot. Now pick your mold, fill the crucible, and show Kovac what true craftsmanship looks like.
