Quick answer: Nuo Mask is found in Mirage Estate, near the Nuo Mask Altar bell, as a reward or pickup in the world. Summon-type Phantom Edges cost 1 less Remnant Spark and summons gain Berserk.
Where to find Nuo Mask
Nuo Mask is in Mirage Estate, close to the Nuo Mask Altar bell. You get it as a reward or pickup in the world. On the Mirage Estate interactive map, the accessory has its own pin, and clicking that pin opens its details.
Before you go for it, rest at the Nuo Mask Altar bell. Bells work as fast travel and respawn points, so if you die, the game sends you back close to the mask instead of somewhere farther away.

Nuo Mask is a “Support” accessory. Its item card lists this effect:
“Reduces the Remnant Spark cost of Summon-type Phantom Edges by 1. Summons gain Berserk, slightly increasing their damage while active.”
The card also carries this description:
“Neither weeping nor smiling, this ghostly mask always fits perfectly, as though it were flesh grown from the wearer’s own face. A person wears a hundred faces, each born of the heart… or is the heart born of the face?”

What Nuo Mask is good for
Nuo Mask is made for builds that use Summon-type Phantom Edges. Summon-type Phantom Edges cost 1 less Remnant Spark, and summons gain Berserk, which adds damage while active. That bonus grows with each polish. The weapons and Phantom Edges list shows which Phantom Edges count as summons, and Incense Ash is the material that upgrades them.
You have three accessory slots open from the start, so the mask can share space with other gear. The full accessories list shows every accessory with its effect and location.
