How to boost Smithing in OSRS

Drink Kovac's grog from the Giants' Foundry reward shop to boost your Smithing level by +4 in Old School RuneScape (OSRS).

This guide also covers the items that boost Smithing XP and speed, the Giants' Foundry and Blast Furnace rates Jagex publishes, and fixes for boosts that do not seem to work.

How to boost Smithing in OSRS with Kovac's grog

Kovac's grog is the Smithing level boost Jagex added with the Giants' Foundry update in June 2022. It gives a temporary +4 to Smithing, and the Foundry is members-only.

1. Train Smithing to level 15, the requirement for the Sleeping Giants quest.
2. Travel to the Giant Plateau east of Al Kharid, near Citharede Abbey, and speak to Kovac to start the quest.
3. Finish Sleeping Giants to unlock the Giants' Foundry.
4. Complete sword commissions for Kovac to earn Foundry Reputation.
5. Spend the reputation on Kovac's grog in the Foundry Reward Shop.
6. Drink the grog right before you start smithing, so the temporary +4 boost covers your session.

Utilizing Smithing boosting potions and items in OSRS

OSRS Smithing boosts come in three kinds: a level boost, an XP boost and a speed boost. Pick the one that matches what is holding you back.

Your goal	Use this	What it does
Reach a level requirement a few levels early	Kovac's grog	Temporary +4 Smithing boost
More XP per bar when smelting at a furnace	Smithing catalyst	Doubles the XP and halves the coal needed; one catalyst is used per bar
More XP per bar at the Blast Furnace	Smithing catalyst	Doubles XP for any bar made with coal, but the coal cost stays the same
Faster anvil smithing	Smiths' Uniform (gloves, boots, top, bottoms)	Each piece gives a 20% chance to save 1 tick; the full set averages a 15-20% speed gain
Gold bars at the Blast Furnace	Goldsmith gauntlets	Jagex estimates about 375,000 XP per hour with them, against about 150,000 without
Extra bars at the Edgeville furnace	Varrock Achievement Diary rewards	A 10% chance to smelt 2 bars at once, extended to higher bar tiers with each diary tier

Experience-boosting items and gear stack in practice: a catalyst affects the bar you smelt, while the uniform affects anvil work and Foundry commissions.

Understanding Smithing in OSRS

Smithing in OSRS has two halves: smelting ore into bars at a furnace, and shaping bars into items at an anvil. Members also get two dedicated training areas.

Activity	Where	What you produce
Smelting	Any furnace, including the Edgeville furnace	Bars from ore and coal
Anvil smithing	An anvil	Weapons, armour and other items from bars
Blast Furnace (members)	The Blast Furnace	Bars in bulk, including gold and steel
Giants' Foundry (members)	The Giant Plateau east of Al Kharid	Giant swords made from 28 bars' worth of metal, paid in XP and Foundry Reputation

Importance of boosting Smithing levels in OSRS

A level boost and an XP boost solve different problems, and mixing them up wastes reward points.

Boost type	Example	Lasts	Best use
Level boost	Kovac's grog (+4)	Temporary	Meeting a level requirement before you have trained to it
XP boost	Smithing catalyst (double XP)	One bar per catalyst	Raising XP per bar while smelting
Speed boost	Smiths' Uniform	Permanent while worn	More actions per hour at an anvil or in the Foundry

Basic strategies for leveling Smithing in OSRS

Match the training activity to your level, your membership and how much coin you can spend. The right ores and items depend on whether you want speed or profit.

Your situation	Focus on	Why
Below level 15 Smithing	Train to 15	That unlocks the Sleeping Giants quest and its 6,000 XP reward
Member who wants steady XP and rewards	Giants' Foundry with Medium or High alloys	Jagex estimates about 135,000-195,000 XP per hour
Member who wants the fastest XP and can afford it	Gold bars at the Blast Furnace with Goldsmith gauntlets	The highest published estimate, about 375,000 XP per hour
You want to earn while training	Steel at the Blast Furnace with a coal bag, or 3-bar rune items	Both are marked as profitable in Jagex's estimates
Free-to-play account	Smelting and anvil smithing	The Giants' Foundry and its rewards are members-only

Effective Smithing training methods and XP rates in OSRS

Jagex published these estimates with the Giants' Foundry update. They are averages, not guarantees.

Method	XP per hour (estimate)	Average GP/XP	Profitable
Gold at Blast Furnace, no Goldsmith gauntlets	~150,000	8.7	No
Gold at Blast Furnace, with Goldsmith gauntlets	~375,000	3.5	No
Steel at Blast Furnace, with coal bag	~90,000	-12.3	Yes
Giants' Foundry, Medium alloy	~135,000	-0.2	Yes
Giants' Foundry, Highest alloy	~276,000	6.6	No
Creating 3-bar rune items	~290,000-310,000	-0.8	Yes

A negative GP/XP figure means the method earns coins. A positive one is the cost you pay for each XP point.

Best items to craft for quick experience in OSRS Smithing

At an anvil, items that use more bars per action give the most XP per hour. These are the efficient bars and products in Jagex's figures.

Item to smith	XP per hour (estimate)	Average GP/XP	Profitable
5-bar mithril items	~190,000-210,000	3.7	No
5-bar adamant items	~240,000-260,000	1.3	No
3-bar rune items	~290,000-310,000	-0.8	Yes
Cannonballs with the Eight-Cannonball Mould	Not published	Not published	Doubles cannonball output per action

The Eight-Cannonball Mould turns two steel bars into eight cannonballs at once, so it suits players who want cannonballs more than fast XP.

Smithing catalyst: how to double Smithing XP in OSRS

The Smithing catalyst is a Giants' Foundry reward. It is unstackable and is used up each time you make a bar.

1. Buy Smithing catalysts from the Giants' Foundry Reward Shop with Foundry Reputation.
2. Carry one catalyst for each bar you plan to smelt.
3. Smelt bars at a furnace to get double XP and use half the usual coal.
4. At the Blast Furnace, use catalysts from the Blast Furnace bank to get double XP on any bar made with coal.
5. Restock catalysts before each session, since every bar consumes one.

Key quests for Smithing XP in OSRS

Sleeping Giants is the quest that most directly aids Smithing progress in OSRS, because it gives XP and opens the Foundry activities. It is a novice quest.

Quest	Requirement	Smithing reward	Unlocks
Sleeping Giants	15 Smithing	6,000 Smithing XP	The Giants' Foundry, its reward shop and 1 Quest Point

Start it with Kovac on the Giant Plateau east of Al Kharid. Events and quests that add Smithing content appear in the official OSRS news first.

Giants' Foundry: activities and minigames to accelerate Smithing

The Foundry is a non-instanced, non-combat safe area. A finished sword pays Smithing XP and Foundry Reputation, and higher quality pays more.

1. Read the commission's two customer requests, such as narrow and spiked.
2. Pick a mould from Kovac's Mould Library that matches both requests as closely as possible.
3. Fill the crucible with 28 bars' worth of bronze, iron, steel, mithril, adamant or rune bars, or with metal items to recycle.
4. Cool the preform at the Waterfall until it is cool enough for the Trip Hammer, then hammer it.
5. Cool it to just below the yellow range and work it on the Grindstone; repeat with the hammer until the sword is almost complete.
6. Cool it to the green range and finish it on the Polishing Wheel.
7. Hand the sword to Kovac at 100% completion to collect XP and reputation.

Use the Lava Pool whenever a tool needs a hotter sword. Using the wrong tool, or the right tool outside its temperature range, lowers quality.

Furnace and anvil efficiency tips in OSRS

Tip	What to do	Gain
Use the correct furnace	Complete the Varrock Easy diary and smelt at the Edgeville furnace	10% chance of 2 bars at once, up to steel; Medium, Hard and Elite add mithril, adamant and runite
Use the Blast Furnace for bulk bars	Bring a coal bag for steel, or Goldsmith gauntlets for gold	Higher XP per hour than a standard furnace in Jagex's estimates
Optimize your Smithing sequence	In the Foundry, alternate cooling with the hammer and grindstone, then finish on the polishing wheel	Fewer quality losses and faster commissions
Enhance your anvil usage	Wear the full Smiths' Uniform	A 100% chance to save 1 tick per anvil action, about 15-20% faster
Additional tips: keep ice gloves	Combine Smiths' gloves with ice gloves	You keep both effects in one glove slot, and can split them again
Additional tips: repeat the last item	Press Space to smith the last item again	Since June 2022 this no longer types a space into chat

Optimizing your Smithing workflow in OSRS

Area	Workflow change	Why it helps
Choose the right locations and equipment	Train at the Blast Furnace or Giants' Foundry with the Smiths' Uniform	Both are built for Smithing and the uniform speeds anvil and Foundry work
Efficiently gather and manage resources	Buy Ore Packs from the Foundry Reward Shop	They are mostly coal, with a small chance of other ores
Implement banking and material management strategies	Withdraw catalysts from the Blast Furnace bank during a run	You can use many catalysts in one trip
Utilize training methods wisely	Use Low or Medium alloys when you want profit, High or Highest when you want XP	Jagex marks only the Low and Medium alloy tiers as profitable
Automation and scheduling	Plan sessions around stocked bars and catalysts; never automate inputs	Jagex allows only approved third-party clients, and others may lead to permanent account action
Participate in events and quests	Complete Sleeping Giants and follow the official news for Smithing updates	New Smithing rewards and changes arrive through game updates

Smiths' Uniform, Smithing skillcape and portable forges in OSRS

The Smiths' Uniform is the OSRS Smithing outfit, bought from the Giants' Foundry Reward Shop. The gear that speeds up training is the uniform, not a cape or forge.

Item	Effect on training	Notes
Smiths' Uniform, per piece	20% chance to save 1 tick on anvil smithing and 20% chance of extra Foundry completion	Four pieces: gloves, boots, top, bottoms
Smiths' Uniform, full set	100% chance on both effects, about 15-20% faster anvil work	Gloves can merge with ice gloves
Smithing skillcape	None while training	It is a reward for reaching level 99
Portable forges	Not available	They are not among the Old School Smithing rewards

Common mistakes to avoid when boosting Smithing in OSRS

Mistake	Result	Do this instead
Drinking Kovac's grog long before you smith	Part of the temporary +4 boost is spent idle	Drink it at the anvil or furnace
Expecting a catalyst to save coal at the Blast Furnace	Coal cost stays the same there	Count on double XP only; the coal saving applies at a normal furnace
Running low on catalysts	Bars made without one give normal XP	Carry one catalyst per bar
Using a tool outside its temperature range in the Foundry	Sword quality drops and cannot recover	Check the HUD before each tool
Letting quality reach 0	You must hand the sword back and start again	Cool or heat the sword before it leaves a tool's range
Choosing the Highest alloy to make money	Jagex lists it as unprofitable	Use Low or Medium alloys for profit

Advanced Smithing techniques and strategies in OSRS

Once the basics are steady, these choices add XP or rewards per hour.

Technique	How it works	Payoff
Mix alloys in the crucible	Combine two or more metals for one sword	Kovac rates alloy swords as better
Climb alloy tiers	Move from Lowest to Highest alloy as your level allows	Average XP per sword rises from ~2,400 to ~23,000
Buy better moulds	Unlock higher-level moulds in the Reward Shop	Higher sword quality before you start shaping
Pair the uniform with commissions	Wear all four uniform pieces in the Foundry	Extra completion on every action
Target catalysts at coal bars	Use catalysts at the Blast Furnace only on bars that need coal	The double XP applies only to bars made with coal there

How to check your Smithing boost is active in OSRS

1. Open the Skills tab right after drinking Kovac's grog.
2. Look at the Smithing entry: the current level should read 4 above your base level.
3. Smelt one bar with a catalyst in your inventory and compare the XP drop with a bar made without one; it should be double.
4. Check that a catalyst left your inventory, which confirms it was used on that bar.

Smithing boost not working in OSRS

No Smithing boost available on a free-to-play account

Kovac's grog, the catalyst and the uniform come from the Giants' Foundry, which is members-only.

1. Train with standard smelting and anvil smithing on free-to-play worlds.
2. Pick up the Foundry rewards once you have membership.

Kovac's grog or the Smithing quest rewards are locked

The Foundry and its shop open only after the Sleeping Giants quest.

1. Train Smithing to level 15.
2. Complete Sleeping Giants with Kovac on the Giant Plateau.
3. Earn Foundry Reputation from commissions, then buy the grog.

Smithing catalyst items not boosting XP or saving coal

Each catalyst works for one bar, and at the Blast Furnace it doubles XP without cutting coal.

1. Carry one catalyst for every bar you plan to make.
2. Use them only on bars made with coal.
3. Smelt at a standard furnace if you want the coal saving as well.
