Before entering a Sub Mission that replays an existing zone in Nioh 3, know this: collectibles don't exist inside them.
The open-world version of Hamamatsu Castle has loot. The Princess Tsubaki Sub Mission that takes you through Hamamatsu Castle has none. Same for Horie Castle, Futamata Castle, the Haunting Caves, Saigagake, Rajomon, Honnoji Temple, and Kiyomizu — sub mission versions of every zone are cleared of their collectible database. Knowing this up front saves a lot of backtracking.
Past that, 30+ Sub Missions across all eras reward Samurai's Locks, Smithing Texts, Secret Skills Texts, and unique weapons that aren't available anywhere else. Every starting point, prerequisite, and full objective list is included on our interactive maps accessed via the Nioh 3 completion hub.
Not all Sub Missions work the same way. Three tutorial missions — Basic Controls, Expanded Controls, and Training Ground — unlock early in Warring States and give no rewards. They exist purely to practice mechanics. Ignore these once you've skimmed them.
The Eternal Rift training series is structured as ranked fights: challenge NPCs in the Eternal Rift to prove mastery of each combat discipline. These are covered in detail below.
Everything else is a story sub-mission — triggered by talking to an NPC, examining a corpse, or completing a prerequisite Myth. These have full objective chains, boss fights, and meaningful rewards.
Most are tied to named historical figures and their personal storylines running parallel to the main campaign. Unlike Myths, they don't require a specific active quest — you trigger them by finding the starting point in the world.
Nine Sub Missions run in three tiers across three disciplines, each accessible from the Eternal Rift:
Within each tier, the Warrior series involves Yagyu Munenori, the Ninja series involves Hattori Hanzo, and the Onmyo series involves Saito Fuku.
Veteran rewards include Smithing Texts for the Great Tengu Blade, Swordmaster's Attire, Demontear Sword, Demon Fang Kusarigama, and Iga Jonin Apparel — making the Veteran tier the most valuable source of weapon blueprints in the Eternal Rift outside of Myth completions.
These four don't give you one boss — they give you four or five.
For all four, the bosses don't scale to your level. Return later at a higher level, and the gap becomes significant.
The Demon's Regimen in Warring States has an objective that catches everyone off guard: Follow Hayatemaru, the Scampuss.
A Scampuss named Hayatemaru guides you through the early section of the mission before the Hattori Hanzo duel. Don't attack it.
The 33+ Sub Missions visible on our maps are documented with full objectives and prerequisites — Warring States area map covers the densest set, including the Haunting Caves chain, Honda Tadakatsu, the Ryotan Temple apparition (triple weapon reward from Ryomen Sukuna), and the Takeda Four Heavenly Kings gauntlet.
Heian interactive map holds Triple Triumph, The Mystery of Rajomon (Ryomen Sukuna again, this time at Rajomon), and Beneath a Pure White Flag.
Bakumatsu map guide covers the Beast of the Underworld, Kiyomizu Defiled, Crucible Tour, the Shinsengumi gauntlet, and the late-game Drawn to Yokai Incense.
The Final Battle of Edo interactive map holds just one Sub Mission — but it's the hardest one in the game, and you can't even see it until the credits roll.
