Best adamantine items in Baldur’s Gate 3: complete guide to weapons and armor

The Adamantine Forge in Baldur’s Gate 3 offers some of the most powerful equipment in the game. From devastating weapons to nearly impenetrable armor, these items can significantly enhance your party’s combat capabilities. Let’s explore the best adamantine items and their unique properties.

Top-tier adamantine weapons

Adamantine longsword

The Adamantine Longsword stands out as one of the most versatile weapons from the forge. This rare +1 weapon deals 1d10 (or 1d8) +1 slashing damage and includes the powerful Diamondsbane property, guaranteeing critical hits against objects. Perhaps its most valuable feature is the ability to ignore slashing damage resistance, making it effective against a wide range of enemies.

Adamantine scimitar

For characters focusing on dexterity-based combat, the Adamantine Scimitar offers exceptional versatility. As a rare +1 weapon dealing 1d6+1 slashing damage, it features both the Light and Finesse properties. This combination makes it perfect for dual-wielding builds and allows it to be used effectively with either strength or dexterity modifiers.

Premium adamantine armor options

Adamantine splint armor

The Adamantine Splint Armor is arguably the most impressive defensive item available from the forge. With an outstanding AC of 18, it provides complete immunity to critical hits and applies a powerful Reeling debuff to attackers for three turns when they land a hit. This armor also reduces incoming damage by an additional point compared to standard variants, making it invaluable for front-line fighters.

Adamantine shield

The Adamantine Shield offers extraordinary defensive capabilities with its +2 AC bonus and critical hit immunity. What sets it apart is its unique Shield Bash reaction ability, which can knock enemies prone and apply the Reeling debuff for two turns to attackers who miss. This combination of offensive and defensive properties makes it an excellent choice for any character proficient with shields.

Adamantine scale mail

For characters restricted to medium armor, the Adamantine Scale Mail presents an excellent compromise between protection and mobility. With 16 AC and the ability to reduce all incoming damage by 1, it provides solid defense while maintaining flexibility. The armor also grants immunity to critical hits and applies the Reeling debuff to melee attackers for two turns.

These powerful adamantine items offer unique advantages that can dramatically improve your party’s combat effectiveness. The combination of damage reduction, critical hit immunity, and special abilities makes them particularly valuable during the early and mid-game phases of Baldur’s Gate 3.

How to find and use the adamantine forge

The Adamantine Forge in Baldur’s Gate 3 is located in the Grymforge area of the Underdark, and accessing it requires careful navigation and preparation. Here’s a comprehensive guide on how to find and utilize this powerful crafting station.

Locating the forge

To reach the Adamantine Forge, you’ll need to:

Travel to Grymforge by boat from the Beach region in the first Underdark area
Head up the stairs from the docks, past the Underdark – Grymforge fast travel sigil
Turn right at the top and follow the path to clear the rubble blocking the way

Gathering essential resources

Before you can craft adamantine items, you’ll need to collect two crucial components: Mithral Ore and specific moulds. There are only two Mithral Ore veins available in the game, making resource management critical. You can find them:

Southwest of the forge entrance, behind a balcony (guarded by Animated Armor)
Left of the stairs leading to the Adamantine Forge platform (protected by Magma Mephits)

For the moulds, you’ll need to explore various locations in Grymforge. The most valuable moulds can be found in these specific spots:

Longsword Mould: Located on the platform past the first set of levers under the iron ladder
Shield Mould: Behind a locked door in the Dormitory
Splint Mould: East of the Waypoint, near a crumbling ledge
Scale Mail Mould: Next to a work table by the Waypoint

Using the forge

Once you’ve gathered your resources, follow these steps to craft adamantine items at the Adamantine Forge:

Insert the Mithral Ore into the Crucible in the forge’s center
Place your chosen mould into the Mould Chamber
Pull the lever to lower the platform
Activate the Lava Valve to flood the platform
Use the forge hammer to initiate the crafting process

Be prepared for a challenging boss fight with Grym, the Adamantine Golem, who appears during the crafting process. Having a well-equipped party is essential, as defeat is necessary to complete crafting. Strategic positioning and proper preparation are key to success.

Important considerations

When using the Adamantine Forge, keep these crucial points in mind:

You can only craft two adamantine items due to limited Mithral Ore availability
Choose your crafting priorities carefully based on your party composition
Ensure your party is properly equipped for the Grym boss fight
Consider using fire resistance potions when dealing with lava hazards

The forge’s location in Grymforge makes it a significant milestone in your journey, and crafting the right adamantine items can dramatically enhance your party’s combat effectiveness throughout the game.

Combat strategies with adamantine equipment

Mastering combat with adamantine equipment in Baldur’s Gate 3 requires understanding how to leverage these powerful items’ unique properties effectively. Here’s a comprehensive breakdown of the most effective combat strategies when wielding adamantine gear.

Defensive positioning with adamantine armor

When wearing adamantine armor, positioning becomes crucial to maximizing its defensive benefits. Position your armored characters at the front lines to absorb damage while protecting more vulnerable party members. The Reeling debuff from adamantine armor works best when you can force enemies to attack your protected character repeatedly.

Keep adamantine-armored characters within enemy sight lines to draw attacks
Use high ground advantages while maintaining defensive positions
Position spellcasters and ranged attackers behind your armored frontline

Shield tactics and reactions

The Adamantine Shield offers unique tactical advantages through its Shield Bash ability and Reeling debuff application. According to combat analysis, the Shield Bash reaction is most effective when:

Using it to interrupt enemy spell casting
Knocking down enemies attempting to flank your party
Creating opportunities for advantage on attacks against prone targets

Weapon combinations and synergies

Adamantine weapons excel at breaking through enemy defenses. Strategic weapon selection should consider your character’s build and role:

Pair the Adamantine Longsword with a shield for balanced offense and defense
Dual-wield Adamantine Scimitars for maximum attack potential with dexterity-based characters
Use the Adamantine Mace against heavily armored opponents

Maximizing critical hit immunity

The critical hit immunity provided by adamantine armor is particularly valuable in certain situations. Combat experts recommend using this feature strategically by:

Engaging enemies known for high critical hit rates
Taking calculated risks in dangerous situations
Absorbing damage while other party members setup advantageous positions

Remember that combining multiple pieces of adamantine equipment can create powerful defensive synergies, making your characters significantly more durable in combat while maintaining offensive capabilities through their unique properties and abilities.

Crafting tips and resource management

Making the most of your adamantine crafting resources in Baldur’s Gate 3 requires careful planning and strategic decision-making. Here’s how to optimize your crafting process and manage your valuable resources effectively.

Resource gathering and preparation

Before heading to the Adamantine Forge, ensure you have gathered all necessary materials. The most crucial resource is Mithral Ore, which is extremely limited in the game. There are only two Mithral Ore veins available, meaning you can only craft two adamantine items in total.

Collect specific moulds for your desired items before mining the ore
Scout the Grymforge area thoroughly to find all available moulds
Consider your party composition when deciding which items to craft
Prepare combat-ready gear before attempting the forge, as you’ll face Grym

Strategic crafting priorities

Given the limited resources, prioritizing your crafting choices is essential. According to experienced players and guides, the most valuable combinations are:

Adamantine Splint Armor + Shield: Optimal for tank builds and maximum survivability
Adamantine Longsword + Shield: Best for versatile combat effectiveness
Adamantine Scale Mail + Shield: Ideal for medium armor users who need mobility

Mould management

The Adamantine Forge moulds are reusable, which means you can keep them for future playthroughs or in case you find additional Mithral Ore. Store your moulds safely after crafting, as they might prove valuable later in the game or in different scenarios. According to GameRant, proper mould management is crucial for maximizing your crafting potential.

Timing your crafting

The optimal time to craft adamantine items is during Act 2, when you first gain access to the Grymforge. These items will provide significant advantages throughout the middle portion of the game. TheGamer suggests that while adamantine items remain useful, their relative power may decrease in Act 3 as more powerful magical items become available.

Resource optimization tips

Always save before attempting to craft, in case of combat difficulties with Grym
Consider your party’s immediate needs versus long-term strategy
Craft items that complement each other and your party’s fighting style
Keep track of which moulds you’ve found to avoid missing any options

By following these crafting tips and managing your resources carefully, you’ll be able to make the most of the limited Mithral Ore available and create powerful adamantine items that significantly enhance your party’s capabilities in Baldur’s Gate 3.
