AC Shadows Secrets & Collectibles: All Shinobi Scrolls, Kofun Artifacts, Legendary Gear & Hidden Ending

I've crawled through every corner of Shadows' feudal Japan and honestly, most collectibles are filler. Random trinkets, merchant ledgers, lost scrolls, they give a trickle of XP and mon that barely registers. But a handful of them unlock permanent stat boosts, gear slots, or even a secret ending scene.\n\n## Shinobi Scrolls: The 30% Difference\n\nThirty scrolls across the map. Each one gives a permanent +1% critical assassination chance. Collect all thirty and you have a flat 30% bonus stacking with gear perks. That's the difference between a guard surviving your hidden blade with a sliver of health and screaming for reinforcements, versus dying quietly.\n\nThey're tucked into temples, behind waterfalls, inside castle interiors. The \"Reveal\" ability at level 8 highlights them within fifty meters. Do not skip this ability. I wasted roughly four hours combing through Iga Province manually before unlocking it.\n\nThe scroll placements teach you to look for environmental cues: a slightly off-color wall panel, a hanging tapestry that's actually a doorway, a statue facing the wrong direction. Once you learn the visual language, finding them becomes methodical.\n\n## Kofun Artifacts: Dual Legendary Weapons\n\nFifteen artifacts in ancient burial mounds around the map. You need ten to equip two legendary weapons simultaneously. Dual-wielding transforms your damage output, it's not a small optimization.\n\nThe burial mounds look like natural hills with small stone entrances. Easy to ride past. Inside there's usually a simple puzzle and a chest. The Osaka Castle artifact is the easiest, shallow cave on the eastern approach, zero enemies. The Mount Hiei artifact requires a mirror-and-light puzzle that took forty minutes. The solution is painted on the wall carvings if you look closely.\n\nGet ten as early as you can. The power spike from dual legendary kusarigama and Shadow Kunai is the single biggest damage jump in the game.\n\n## Haiku Poems And The Secret Ending\n\nTwenty haiku at scenic spots around the map. They don't boost stats. They don't unlock gear. But find all twenty and you get a secret ending scene after the credits that ties into some deep lore from earlier AC games. Won't spoil it.\n\nThe haiku markers are small stone tablets with calligraphy, always facing a scenic view. Mountain peaks, lake shores, temple gardens. Eagle Vision highlights them. I stumbled onto my first one on a cliff overlooking Lake Biwa and spent the next week hunting the rest.\n\nThe poems themselves are actually decent. Each reflects on the landscape you're looking at, and the collection as a whole tells a subtle story about a character from the wider AC universe. The kind of thing most players will miss entirely.\n\n## Legendary Gear Hidden In Plain Sight\n\nShadow Walker outfit: Kofun Ruins south of Kyoto. Complete the \"Echoes of the Past\" puzzle, rotate three stone tablets to match constellation paintings on the ceiling. Reduces detection range by 15%. Subtle but in tight interiors it's the difference between slipping past and triggering an alert.\n\nBlade of the Ronin: Nagoya Castle treasury. Legendary katana, +20% assassination speed. Can't fight your way in, too many guards. Pickpocket the castle steward in daytime while wearing a guard disguise (uniforms are in nearby barracks). The pickpocket window is tight, save beforehand.\n\nFox Mask: Hidden cave near Mount Hiei. Defeat a level 25 Ronin boss. Mask makes enemies take roughly 10% longer to alert. I use this constantly because the extra delay is often exactly enough to reposition after a near-miss detection.\n\nWind's Whisper bow: Iga Province shrine. Complete five timed grappling trials. Arrows make zero noise and don't break stealth even on a miss. The trials are platforming challenges against a clock, took me about six attempts per trial. Worth it for the silence.\n\nShadow Kunai: Abandoned temple in Honshu. Water puzzle, rotate three statues using wall painting clues. +20% stealth attack damage.\n\nSilent Treads: Iga abandoned dojo. Beat the Ronin Master without taking a hit. 90% movement noise reduction.\n\n## The Hideout's Hidden Depth\n\nYour hideout does more than look pretty. Recruited allies form a spy network. Each ally type provides different intel: scout reveals patrol routes and legendary chests, strategist marks target weaknesses, quartermaster unlocks crafting discounts.\n\nUpgrading the hideout adds fast travel beacons in each province. Without these you'll spend half your playtime on horseback between locations.\n\nThe hideout physically transforms with seasons. Winter ices over certain paths. Spring spawns harvesting nodes. Build the garden early, it passively generates materials each season transition.\n\nHere's something I found on my second playthrough: if you recruit all three ally types before tackling inner ring targets, you get a unique dialogue scene where they discuss strategy together. Adds nice flavor to what's otherwise a purely mechanical system.\n\n## What To Skip\n\nA hundred-some minor collectibles: trinkets, ledgers, random scrolls. Tiny XP and mon. Not worth detouring unless you're a completionist.\n\nThe horse-racing challenges award a saddle that slightly increases horse speed. Unless you genuinely enjoy the racing minigame, skip them.\n\n## Efficient Collectible Route\n\nThe map is about 30% larger than Valhalla's England. You can't wander and hope. I used this route: start Iga Province, clear all scrolls and artifacts. Move clockwise through regions. Unlock hideout fast travel points as you go. Keep Revel active constantly. Listen for the audio cue, a subtle flute note, near collectibles. Easy to miss if you're distracted.\n\nThe power spike from all thirty scrolls and ten artifacts reshapes your damage profile. Put on a podcast, this takes a while, but the results change how smoothly every subsequent infiltration plays out.

Hidden Blade Upgrade Locations (Because You'll Need These)

Tier 2 upgrade kit: Hidden Blade Cache in Iga, behind the waterfall during the prologue story mission. Unmissable if you follow the objective marker, but easy to walk past if you're exploring earlier without triggering the mission.

Tier 3 upgrade kit: Assassin's Tomb inside Osaka Castle. This one is genuinely hidden. The entrance is a vertical shaft in the castle's lower level that isn't marked on the map and doesn't glow in Eagle Vision. You need to parkour up a series of wall indentations that don't look climbable. I found it by accident while trying to escape a botched infiltration and suddenly realized the shaft was actually an intentional path, not a level boundary.

Tier 4 upgrade kit: reward for collecting all thirty Shinobi Scrolls. This is the hardest upgrade to get and honestly overkill for the main story. By the time you have all thirty scrolls you've probably cleared most of the game anyway. But for New Game+ starts, having tier 4 from the beginning trivializes the first act's elite enemies.

New Game+ Collectible Changes

NG+ respawns all collectibles but gives them different rewards. Shinobi Scrolls drop skill points instead of critical chance bonuses in NG+. Kofun artifacts give crafting materials. Legendary gear chests contain upgraded versions of their base-game items with slightly different perk rolls.

The Haiku collection doesn't reset, which is nice because finding all twenty once was enough for me. The secret ending unlocks permanently on your save file once you've seen it, carries over to NG+.

What does carry over: all gear, all skills, all hideout upgrades, fast travel beacons, and the spy network intel. What doesn't: mission progress, target board state, and any temporary buffs active when you finished the previous run. You start NG+ at the prologue with endgame equipment and all enemies scaled up accordingly.

The power fantasy of running the Iga Province prologue with dual legendary weapons and tier 4 hidden blade is genuinely fun. Guards that gave you trouble in your first playthrough die before their detection meter fills a single segment."
