How to Get Adamantine Longsword

Craft in the Adamantine Forge

Adamantine Longsword Location
Can be obtained after finding a Mithral Ore and the appropriate Mould in the Ancient Forge. Use the Adamantine Forge to craft this weapon by placing the Ore in the crucible and putting the Mould in the chamber.

Adamantine Forge Guide

Mould Location

The Longsword Mould can be found right after you get on the hanging bridge near the first pair of levers.

Mithral Ore Locations

Near the Stairs of the Adamantine Forge

Go down the stairs that lead to the Adamantine Forge. Look towards the northeast and you'll see a Mithral Vein. Jump your way down towards it but prepare to be ambushed by some enemies.

You will encounter five Magma Mephits and they are resistant to fire, cold, and poison. They explode on death so try to not let them get close. They can also disarm so if you have an Eldritch Knight on your party, use Weapon Bond before combat.

Southwest of the Ancient Forge Waypoint


Map Location	World Location

Head southwest from the Ancient Forge Waypoint. Get up the platform and you'll see another Mithral Vein. Use Feather Fall or other mobility spells to safely get across. You can make your way back up by teleporting to the Ancient Forge Sigil from your map.
