- — In-game description
The Dark Tunic is an item from The Legend of Zelda: Breath of the Wild. It is a body armor which Link can purchase from the Fang and Bone shop for 999 Mon. It is a special tunic, a jet-black replica of Hero's Clothes created by Kilton and based on the result of Kilton's monster research implying to have been based on the black tunic worn by Dark Link. It is part of the "Dark" armor set which makes Link look like Dark Link when worn with the other two pieces. Wearing all three pieces grants a Night Speed Up bonus that increases Link's movement speed during nighttime. This nighttime speed boost is identical to that of the Sheikah outfit. Unlike most other armor pieces, the Dark Tunic (along with the rest of its set) cannot be upgraded, giving it a very poor defense potential.
When wearing the complete Dark set, Link causes other characters to react in alarm, though they can still be interacted with normally.
