The Devil's Corridor (悪魔の回廊) is a section in Darm Tower. The corridor is filled with a devilish noise that quickly reduces the player's HP. The noise is created by wind blowing through pipes on the pillar outside of the tower. The method to deal with the noise varies with the playing character.
In Ys I: Ancient Ys Vanished: Omen, the corridor is a long stretching corridor with a safe room in which Raba is hiding.
In Ys Origin, the corridor is part of the Guilty Fire section and is a long winding slope with two openings leading to a Roo and a treasure chest.
In game[]
Ys I: Ancient Ys Vanished: Omen[]
Adol needs to use the Hammer he found in the boss room on Floor 9 to break a pillar on Floor 11 on the other side of the tower.
Ys Origin[]
In Ys Origin, the player needs to first rush to an opening section on the right side and feed the Roo there with a roda fruit.
When playing as Yunica, the roo will hum Feena's theme and Yunica will be able to play it with the Silver Harmonica to neutralize the noise.
When playing as Hugo, the roo will give him a hammer so that he can break a pillar on Floor 11, the same way Adol passes through the corridor in Ys I: Ancient Ys Vanished: Omen.
When playing as Toal, the roo will present him the Ring of Ease that reduces his MP consumption. This allows him to quickly destroy the glowing enemies in the corridor to deactivate the noise.
