In Baldur’s Gate 3, Adamantine Splint Armour is a craftable heavy chest piece, and you can get it from Adamantine Forge in Act 1 – this short Guide Explains everything you need to know about The Adamantine Splint Armour in BG3.
Adamantine Splint Armour
In Baldur’s Gate 3, The Adamantine Splint Armour has a high Armor Class (AC) of 18, immunity to critical hits, the beneficial Reeling status effect, and a solid 2-point damage reduction. It’s a must-have item in Act 1, especially if you play as a Fighter, Paladin, or one of the Cleric subclasses (Life, Nature, Tempest, and War). The AC it offers can carry you through even to Act 3, reducing the need for frequent armor upgrades. However, it has a limitation—it’s best suited for specific classes and subclasses or may require a feat to gain proficiency in heavy armor.
For main characters who are Paladins or Fighters, using your Mithral ore for crafting this armor is highly recommended. As you progress into Act 3, consider upgrading your armor, first with the Armour of Persistence and later with the Helldusk Armor. You can equip it to your character’s chest slot in the inventory. The user needs Heavy Armour proficiency or suffers penalties while wearing the armour. You can equip it on any class, companion, or character with Heavy Armour proficiency.

How to Get Adamantine Splint Armour in Baldur’s Gate 3
To get the Adamantine Splint Armour in Baldur’s Gate 3, craft it in Adamantine Forge, located in Grymforge, during Act 2. You must find Mithral Ore and Splint Armour Mould and defeat Grym first.

There are six craftable adamantine gear pieces to craft, but only two Mithral ore (check the locations on the map above). First, you can find Mithral ore northwest of the ruined staircase that leads straight to the Adamantine Forge. The second location is to the east, where you’ll need to make a jump over the lava and be careful not to step inside to collect it. Simply destroy the more veins to obtain it.
