Oro

"It is the law of the Great Nailsage that I must pass down my teachings to those who are worthy. But no law forbids me from exacting a payment for my time."

- Nailmaster Oro

Nailmaster Oro is one of three Nailmasters in Hollow Knight. He teaches the Dash Slash to those willing to pay him for his services. Oro also appears as a boss as part of the Brothers Oro & Mato dual fight.

Lore Oro learnt the Nail Arts from the Great Nailsage Sly along with his brothers Mato and Sheo. Of the three disciples, he was the second most skilled, with his signature move being the Dash Slash. While Oro is respectful of the Nailsage's teachings, he was reluctant to obey them to the letter.

Oro always seemed haunted by something. After a falling out among the Nailmasters, he chose to move away in seclusion. He did not leave his brother Mato in good terms and still owes him something. He set a hut in the far reaches of the Kingdom's Edge to avoid company.

In-game events Oro can be found in his hut at the end of the Kingdom's Edge. Reluctant of the Knight's company, however, he concedes to teach them the Dash Slash for. While always being uninviting, Oro does not hide his appreciation of the Knight's skills as a disciple. He will comment on each of the Nail Arts the Knight has learnt while remembering his brothers and master. He even asks them to tell Mato to wait a bit longer before Oro gives him what he wants. When the Knight finally becomes a Nailmaster, Oro hopes that his participation in their training helped redeemed him a bit towards the Nailsage.

Oro's mind is summoned to Godhome by  the Godseeker. There, he defies the Knight to prove his worth in the Nail Arts. Upon being seemingly defeated, his brother Mato appears. While they stare at first at each other with unveiled intensity, Mato's unexpected assistance invigorates Oro. They then help each other to fight the Knight. After both are defeated, they bow respectfully to their opponent. The Brothers Oro & Mato are mainly fought at the peak of the Pantheon of the Master and later within the Pantheon of Hallownest.

Additionally, the Knight can bring a Delicate Flower to Oro in his hut in Kingdom's Edge. He refuses it, telling the Knight he will throw it away if they leave it to him. Yet, Oro will have put the flower in a vase upon the Knight's return to his hut.

Location
Nailmaster Oro is found in Kingdom's Edge

Trivia

 * Oro is the only Nailmaster who must be paid in order to learn his Nail Art.
 * To the east of Oro's house is the impaled corpse of a Great Hopper dressed in a Nailmaster outfit, most likely used as a training dummy. Attacking it with the Dream Nail reveals the dialogue: "Stronger... Brothers...". When it is attacked enough times (25 attacks), two live Great Hoppers fall from the ceiling and attack the Knight.
 * Leaving the room will reset the dummy, allowing it to be attacked again to summon two more Great Hoppers.
