Otherworldly Copper is the refined copper reported to raise Martial Phantom Edges past level 10 in Phantom Blade Zero, and it first appears in the Village of Lu. An early pair rests on a shrine behind the Village Auntie, inside the large house on the hill northwest of the Well of the Three Puppets Bell. The Phantom Blade Zero Village of Lu map with the hilltop house pins it.

Each copper stack on this page was collected on PS5 for Map Master, and the Phantom Blade Zero edge upgrade guides and region maps cover the materials for the other edge types. Stacks grow as you travel, from pairs in the village to stacks of up to four in Pangzhen and a single stack of nine in the Mandate Encampment.
Otherworldly Copper only matters once a Martial edge reaches level 10. Below that, the Exotic Copper Ingot for Martial levels 1 to 10 does the work, so the two tiers never compete for the same upgrade. The Martial edges are reported to be the Hunter’s Chain Sickle, Iron Gauntlets, Fire Meteor, Thunder Spear, and Ink Cut.
Edge upgrades are reported to skip Solvent, so copper and Remnant Dust are the whole bill, and the Martial Phantom Edges this copper upgrades compare their stats. Check which one you actually equip before you spend, since Artifice, Destructive, and other edge types use their own materials.
The Village Auntie waits on the ground floor of that hilltop house, and you can fight her there before taking the copper from the shrine behind her. It’s among the first Otherworldly Copper you’ll find, which makes the house a priority stop once your first Martial edge nears level 10.
A second pair waits on a pile of logs outside Young Master Lan’s Hideout. Lan’s Tale is reported to need a return visit before you enter Pangzhen, so grab the copper then, and the Young Master Lan Tale and its Pangzhen chapter covers when to go back.
Pangzhen & Mirage Estate gives stacks of two, three, and four, and Fire Meteor and Thunder Spear are reported to come from the same region, so new Martial edges and the copper to push them past level 10 arrive together. The Phantom Blade Zero Pangzhen & Mirage Estate map of the city streets places each stack, and Fire Meteor is reported as the reward for the Blaze boss fight in Pangzhen.
The Mandate Encampment has the biggest single stack, nine Otherworldly Copper in one spot, more than any village or Pangzhen find. The Phantom Blade Zero Mandate Encampment map from the gate inward pins it, so save a late upgrade for that trip if Pangzhen leaves you short.
Pick your main Martial edge before you cross level 10. Levels under 10 are reported to refund for free, but undoing anything past that is reported to need a Phantom Reforge Talisman for Martial edge refunds, so the copper you spend from here on is close to permanent.
Upgrade one edge, not two. Pairs only go a short way, so put the village copper into the edge you fight with most, such as the Iron Gauntlets for close fights. The Sickle’s grapple works at any level, so it needs copper only if you use it in combat, and Pangzhen’s bigger stacks can go to the new edges that arrive there.
