How to Get Otherworldly Copper in Phantom Blade Zero

Quick answer: Collect five Otherworldly Copper from a corpse on the Crimson Manor shaft’s fourth level. Another option is to purchase it from Quick Hand Zhang for 1,240 Remnant Dust at either his Pangzhen or Meigu Village hideout.

Otherworldly Copper is the material that takes Martial-type Phantom Edges past level 10. You can pick it up in the world or buy it.

What it does

The item card lists Otherworldly Copper under “Phantom Edge Upgrade Materials” and describes it this way:

“Its raw ore is hard enough to resist blade and axe, yet its surface is riddled with holes corroded by something unnatural. It must be washed in strong acid and tempered in blazing fire, again and again, to produce this refined ingot.”

Below that, the card states its use: “Required to upgrade Martial-type Phantom Edges from Lv. 10–20.”

It sits in the middle of three copper tiers for Martial-type Phantom Edges.

Material	Upgrade range
Exotic Copper Ingot	Up to Lv. 10
Otherworldly Copper	Lv. 10–20
Forged Otherworldly Copper	Lv. 20 to max

Where to find it

Crimson Manor shaft

Head down the shaft beneath the Crimson Manor. The falls between the nets do not hurt, so you can drop from one to the next.

At the fourth level, walk off the net. The drop is short and deals no damage, and you land right next to a body with a white glint.

Press E at the glint. The pickup message reads “Otherworldly Copper + 5”.

South Town Pond chest

Travel to the South Town Pond bell in Pangzhen.

Find the chest beside the bell, by the lotus pond.

Open the chest. It holds one Otherworldly Copper, along with Concentrated Solvent and Camphor Timber.
