Reaching the ancient Adamantine Forge in Baldur's Gate 3 is a major milestone that grants access to some of the strongest mid-game equipment. However, because players are limited by the scarcity of Mithral Ore, choosing which items to craft requires careful planning. Prioritizing gear that offers long-term defensive utility will significantly ease your journey through the subsequent acts.

Top Tier S-Rank Heavy and Medium Armors

The Adamantine Splint Armour and the Adamantine Scale Mail stand out as the absolute best choices available at the forge. Both of these exceptional armors completely protect the wearer from receiving critical hits while reducing all incoming physical damage. Furthermore, they apply the Reeling condition to attackers, which drastically lowers the accuracy of subsequent enemy strikes.

Choosing between these two pieces depends entirely on your current party composition and build requirements. The heavy splint version provides an excellent flat Armor Class of 18, making it ideal for frontline fighters or paladins. On the other hand, the medium scale variant allows agile characters to benefit from their Dexterity modifier while maintaining top-tier protection.

The Essential Shield for Essential Defense

For players who prefer a defensive playstyle, the Adamantine Shield is a top-tier option that remains relevant deep into the late game. Similar to the full armor sets, this shield grants complete immunity to critical hits and inflicts a stacking attack penalty on missing foes. It provides a massive survivability boost to spellcasters like Shadowheart or college of swords bards who regularly rely on shields.

Crafting this item is highly recommended if your primary damage dealers are already equipped with strong magical armor sets. It offers incredible flexibility since it can be easily swapped between different companions depending on your tactical needs. This makes it a highly efficient use of your limited crafting materials throughout the campaign.

Lower Tier Weapons and Tactical Alternatives

While the forge allows you to create weapons like the longsword, mace, and scimitar, these options generally fall short compared to the defensive gear. These weapons share the Diamondsbane property, which guarantees critical hits against inanimate objects but offers less impact in standard combat. Players will quickly find superior offensive alternatives as they progress into Act 2 and beyond.

If you absolutely need a weapon replacement, the Adamantine Longsword offers versatile utility for characters who specialize in versatile melee fighting styles. However, using your rare ore on a temporary offensive tool is rarely worth bypassing the permanent protection provided by the armor options.
