Ō-yoroi

Ō-yoroi—also known as great armor or Wall armor—is the heaviest armor worn by Crab samurai, and possibly the heaviest armor in Rokugan. These are huge, boxy, often ornate suits used by high-ranking Crab officers and powerful samurai assigned to Wall duty. The armor features all the components of lighter, lesser armor, but on a grander scale. Massive sode cover the wearer’s arms nearly to the wrist, thick iron plates and countless steel scales are laced together then lacquered to provide unparalleled protection, and outsized crests decorate the conical helmets with their monstrous masks.

All this protection and glory comes at a price, however. Since these suits were designed to serve on the Wall, nearly all their protection is focused on the wearer’s front.

While you wear ō-yoroi, if are suffering the Disoriented, Dazed, or Immobilized condition, treat your physical resistance as 3 as your foes can strike at your lightly armored back.
