The Amrine tuning orb, a key required to enter the Amrine Excavation expedition, can be acquired through quests or by crafting the orb at a stonecutting table. One member of your party must have the orb to enter the expedition. That person’s orb is consumed upon use.
Several quests give this orb to allow you access to the expedition: Destiny Unearthed, which is part of the main questline; Foreman’s Ledger (Expedition); and Seeing Clearly (Expedition). Each of these quests will give you one orb.

If you’ve used these orbs and need more, you can craft them at a tier-three stonecutting table. You’ll need the following materials: corrupted sliver x10, iron chisel x1, stone block x50, eternal heart x1.
Corrupted slivers can be found in chests rewarded for closing corrupted portals. You can purchase the iron chisel from your faction representative in any major town. Stone blocks can be crafted from stone. And the eternal heart is also crafted at a tier-3 or higher stonecutting table using death motes, life motes, and soul motes.
Beyond the requirement to unlock the Amrine Excavation, having the Amrine tuning orb makes you an easy choice when people are looking for group members. Complete the quests or craft the orb at a stonecutting table, and you’ll be running the expedition in no time.
