The Sakai Horse Armor is protective gear for Jin's horse from the Iki Island Mythic Tale The Legacy of Kazumasa Sakai. While you ride, you shrug off more hits, and your horse charge hits much harder.
Play The Legacy of Kazumasa Sakai on Iki. Jin pulls the armor from the wrecks of a merchant fleet in Zasho Bay and uses it to defend the Sheltered Campsite.
It once protected Kazumasa Sakai's war horse. Raiders took it after his death on Iki, and riders who used it kept dying, so they sold it as a cursed trophy before the ship carrying it sank.
