Quick answer: Grab 15 from a beach glint in the Whiteshadow’s Fall sea cave, then 4 each from the One-Eyed Isle house chest and the Mount Soulrend hut chest.
Whiteshadow’s Fall sea cave beach (x15)
This beach has the biggest single pickup. At Meigu Lake, rest at the Whiteshadow’s Fall bell, then enter the sea cave beneath the cliff, packed with broken boat decks.
Wade deep into the cave through the glowing water. It stays shallow the whole way, so you never need to swim. About 100 m from the lake edge, you pass a plank deck with stacked crates and a hanging lantern.
Keep the rock wall at your side as you leave the deck. Pass the red-lit rock outcrop; a dark beach lies about 30 m farther along.
At the shoreline, spot a blue shimmer facing the glowing cave entrance, with a wrecked ship farther out. Press E to collect it; the notice displays “Flawless Twinned Metal + 15”.
One-Eyed Isle house chest (x4)
On One-Eyed Isle in Meigu Lake, the chest is in an elevated timber house, a few metres from the table with the Sharpshooter’s Eye. Start at the One-Eyed Isle Dock bell and travel about 140 m through the old arena; then head up the hill to the house.
The chest contains Universal Solvent + 4; it also holds Flawless Twinned Metal + 4, followed by Polished Forged Metal + 7.
Mount Soulrend hut chest (x4)
Passing the Path of Silver bell triggers a brief cutscene. Follow the road past the dead Order soldiers and spears, then climb the stone steps toward the rock face, with a hut above. Point your view at the cliff’s summit; when the “L Ctrl” prompt appears, press Left Ctrl to grapple upward.
Inside the hut, press E to open the chest beside the wooden railing. Its contents include Traversal Talisman + 6. It also has Flawless Twinned Metal + 4, along with Universal Solvent + 16. The final item is Flawless Forged Metal + 15.
