How To Get Adamantine Splint Armor In Baldur’s Gate 3

Adamantine Splint Armor in Baldur's Gate is one of the best heavy armors that can inflict serious damage on the attacking enemies in addition to defense.

Armors are essential in Baldur’s Gate 3 as there are many threats in the world that you encounter during your journey. Despite being an open-world adventure game, it offers only a handful of craft-able items. Adamantine Splint armor is one of these, which you can forge during the Adamantine Forge quest by finding both Mithral Ore and Splint Mould in BG3.

How to Craft Adamantine Splint Armor in Baldur’s Gate 3

Adamantine Splint armor can only be crafted inside the Ancient Forge located in the Underdark. However, to craft this armor, you need two different items. Splint Mould and the Mithril Ore. Once you get both items, you can start the crafting process.

To find the mould, head to the Ancient Forge located in the Underdark. Once you are at the Forge, move to the East side of the Forge and head downstairs. There, you will find the Splint Mould near a skeleton at the coordinates (X: -592, Y: 312).

How to get Mithril Ore in Baldur’s Gate 3

The next thing you need to craft the armor is a mithril ore. You can find the Mithral ore easily as there are big chunks of rocks near the forge. Hit those rocks with a blunt or bludgeoning weapon, and they will drop Mithral Ore.

Craft the Adamantine Splint Armor

Now you have all the things you need, it’s time to craft the armor. Go to the center of the forge and place the Mithril Ore there. Now, place the Splint Mould in the mould chamber near the center. After placing these two at their desired location, pull the lever located on the right side of the mould chamber.

A Hammer will smash the center of the forge, and it will start moving down. Once the forge stops, rotate the lava wheel. This will make the Lava rise, and a boss fight will start. Defeat the Boss, pull the lever once again, and you will find your crafted Adamantine Splint armor on the Mould Chamber.
