Kensei Armor
The Kensei Armor is a unique armor set in Ghost of Tsushima, acquired by completing a specific Mythic Tale. These special side quests are given by musicians throughout the island and often end with a boss battle. Obtaining the Kensei Armor requires successfully finishing its associated Mythic Tale.
Mythic Tales are a type of side quest in Ghost of Tsushima that reward players with either a Mythical ability or a special piece of armor. These quests are initiated by finding and speaking with musicians located across Tsushima. Many Mythic Tales culminate in a boss battle, so preparing for combat is advisable. The Kensei Armor is one of several armor sets available in the game, which also include the Ghost Armor, Fundoshi Armor, Tadayori's Armor, and Gosaku Armor.
The Kensei Armor falls under the 'Armor' equipment category, alongside other gear such as Swords, Bows, Major Charms, Minor Charms, Helmets, and Masks. Unlike story-progression locked items, the Kensei Armor is found by exploring the open world and completing its specific Mythic Tale.
