Loaded Shuriken

A Shuriken Wheel Prosthetic Tool, fitted to the Shinobi Prosthetic. Costs Spirit Emblems to use. Pull a shuriken loaded into the wheel and launch it at a target in a single, flowing motion. The swiftly thrown shuriken damages enemy Vitality and Posture, particularly against those with a tendency to take to the air.

Press the Prosthetic button to fire a Shuriken, which deals with a small amount of damage. For later upgrades, hold the Prosthetics button to charge the shuriken up for multiple hits, dealing slightly more damage and posture. This is the most used Prosthetic tool, at least for me. Useful for keeping an enemy’s Posture up.

Shuriken Wheel – Shuriken Wheel can be found at the Outskirts Wall – Gate Path Idol. This can be looted from a corpse that you’ll find through a hole of a building that is near the Idol.

Flame Vent

A Prosthetic Tool made from a loaded Flame Barrel. Costs Spirit Emblems to use. Deals fire damage to enemies via a short-range blast of fire while also inflicting Burn status. It is difficult to control the rage of those with ‘Red Eyes’ through the power of man alone. They do, however, fear the flame above all else. This tool has the power to make them tremble.

Release a burst of flame in front of you, dealing fire damage and building up the “burn” status effect on any enemies hit. Besides being useful against the Chained Ogre mini-boss, this prosthetic tool is also extremely effective against enemies with flammable straw/chaff overcoats, requiring only one use of the tool to inflict the burn effect. These enemies include cannoneers and certain samurai with the aforementioned overcoats.

Flame Barrel – Flame Barrel can be found at the Estate Path Idol, Hirata Estate. From the Estate Path Idol, head Northeast to eventually find a campfire that is surrounded by enemies. The Flame Barrel will be inside the fire.

Loaded Axe

A Prosthetic Tool loaded with a heavy Shinobi Axe. Costs Spirit Emblems to use. The strength of the Loaded Axe lies in its heft. One strike can easily turn a wooden shield into splinters or shred an enemy’s posture.

Press the Prosthetics tool button to wind up a heavy overhead slam attack that will shatter a foe’s shield. Pressing the Sword Attack button after the final slam will follow up with a second slam using both sword and Axe that does extra Vitality and Posture damage. After performing Whirling, you may also simply opt to replace the follow-up slam with a Fang and Blade by pressing the Sword Attack button after the spin move, which may be useful if you don’t have time to chain the resulting slam into a Fang and Blade.

Shinobi Axe of the Monkey – Shinobi Axe of the Monkey can be found at Hirata Estate. From the path after acquiring the Flame Barrel, you’ll come across a dying man who will tell you about an ax. You’ll find a courtyard where two guards are talking and you can eavesdrop and listen on their conversation about their next plan of burning a temple – kill the two guards, and open the small garden house where the guards were standing to find the material.

Shinobi Firecracker

A Prosthetic Tool fitted with Robert’s firecrackers. Costs Spirit Emblems. Unleashes an explosive flash that briefly blinds foes and inflicts Posture damage on beast-type enemies. Has a wide, frontward field of effect that can impact multiple foes at once. Suitable for temporarily immobilizing enemies and particularly good for scaring beasts.

Use to deploy Shinobi Firecrackers that stun enemies, make them vulnerable to any kind of attack. Particularly useful against animals and beasts, many of which have specific animations when frightened by the firecracker that leaves them highly vulnerable. Can use defensively to create breathing room to heal or apply buffs in combat against aggressive enemies. If used repeatedly against certain enemies, it will become less effective as the fight goes on. After one use on such enemies, you need to wait a significant amount before you will be able to stagger them again.

Robert’s Firecrackers – Robert’s Firecrackers are sold by the Crow’s Bed Memorial Mob. He is located high up on the cliffs between the Outskirts Wall – Gate Path and Outskirts Wall – Stairway Idols, requiring several grappling hooks jumps to reach. The cliff is near the old lady NPC.

Loaded Spear

A Prosthetic Tool loaded with Gyoubu’s Broken Horn. Costs Spirit Emblems to use. Unleash far-reaching thrust attacks. Lighter enemies struck by the spear may be dragged towards the wielder. Those of large build will at times force themselves into poorly-fitting armor. Such armor could be torn clean off; coined by Gyoubu as Armor Stripping.

Press the Prosthetic Tool button to perform a thrust attack with the spear, piercing forward with an unblockable attack. Repressing the button pulls the spear back, tearing armor off larger enemies and drawing lighter enemies towards you. The spear can be used during the second phase of the Guardian Ape fight to pull the Immortal Centipede out from inside the ape, dealing with significant Vitality and Posture damage.

Gyoubu’s Broken Horn – Located in a treasure box in Ashina Reservoir, but you must acquire the Gatehouse Key to get inside. If you have progressed through the story to the point where the Gatehouse is inaccessible, it can be purchased for 2800 sen at the offering box near the Dilapidated Temple.

Mist Raven

A Prosthetic Tool loaded with the feather of a Mist Raven. Costs Spirit Emblems to use. When attacked in the assumed stance, disappear like the mist and move away. Once you think you’ve caught one, all that will remain is feathers. That is the mark of a true Mist Raven.

When attacked in the Mist stance, instantly move in the direction chosen by the player. This gives you a teleport of sorts through enemies, granting some invulnerability. Keep in mind that this tool does not work against grab attacks. It is also a really useful tool for getting away from a very hard enemy and sometimes bosses. If you are running low on healing items, make sure you take advantage of it because it could save your life in the fight.

Mist Raven’s Feathers –It is located in Hirata Estate, near the Bamboo Thicket Slope Idol. You’ll find the Mist Raven’s Feathers inside a hidden temple. To access it, go up from the idol, grapple left and drop into a body of water. Swim past the bridge and then grapple to a branch. You’ll pick up an item and can look right to slash through bamboo. Wall-jump up to the next clearing and you’ll face an enemy that is defending the location.

Loaded Umbrella

A Prosthetic Tool created by fitting an indestructible Iron-ribbed Umbrella to the Arm. Costs Spirit Emblems to use. When spread open, it will protect against attacks from all directions. Hold it out while moving to protect from light attacks. But this is an umbrella after all. It won’t protect you from low attacks such as sweep attacks.

Spread the Loaded Umbrella to guard against attacks in all directions. You can also move with the fan deployed, and it will continue to block lighter attacks as you move. Your posture bar will not decrease until you close the Umbrella. With the Projected Force skill unlocked, the Umbrella can also be used offensively. Pressing the attack button while the Umbrella is open will activate a cross slash attack. Sword Saint Isshin is very weak to the Umbrella in his 3rd and 4th phases.

Iron Fortress –  The Iron Fortress tool is sold by the merchant Blackhat Badger for 1600 Sen. He is located inside a building near the Old Grave Idol in Ashina Castle. After you revisit Ashina castle for the second time and kill the boss, if you have not purchased the tool beforehand it will be on the ground where the merchant originally was.

Sabimaru

A Prosthetic Tool made with the blade Sabimaru, allowing for a quick series of attacks together with the sword. The blue, poisonous rust on Sabimaru’s blade applies “Poison” status abnormality. Wielded in wars of old, the blade’s blue rust was used to drive off inhuman Okami warrior women. Even now, it is likely to be effective against their descendants.

Perform a Flurry of attacks with both the sword and Sabimaru. Sabimarus attacks inflict the “Poison” Status abnormality. It is extremely effective against the gun-wielding enemies, Shirahagi and Shirafuji, and also against the Okami Warriors in Fountainhead Palace. Be mindful that while it’s sprit emblem cost is 1, this only applies to every single two-hit combo. Using the full 6-hit combo would cost you a total of 3 sprit emblems.

Sabimaru – Sabimaru can be found at Ashina Castle. Go to Upper Tower – Antechamber Idol and find this room patrolled by 1 old woman and 2 blue Samurai. There are two holes in the center of the room. Dropping down the hole will introduce you to 1 Blue Samurai and 3 goons. This area allows you to open the main gate of the castle and allows you to get the Sabimaru.

Divine Abduction

A Prosthetic Tool loaded with a large fan. Costs Spirit Emblems to use. Gathers and releases a gust of wind, forcing enemies caught by the vortex to turn around. It is a mild sort of being spirited away that can be returned from quite quickly. However, it’s said that one can only return from being spirited away once, and if taken again, there is no coming back.

Use the fan of leaves to wrap yourself in whirling, glowing winds. It is especially useful against the Senpou Monks on Mt. Kongo because it instantly kills them when you use this tool on them. If you can group them up into a massive group, use the fan on them and you can take out tons of them in a short amount of time. Just make sure you get up high before doing so or else you will get hit.

Large Fan – After defeating the Long-Arm Centipede Giraffe in the Sunken Valley, approach the Buddha statue in the middle of the room where you can acquire the upgrade material.

Finger Whistle

A Prosthetic Tool created by fitting a slender finger to the prosthetic. Costs Spirit Emblems to use. Its sound will grab an enemy’s attention and draw them to the whistle’s location. By locking on to a target, only the targeted enemy will hear the whistle. The sound of the finger whistle enrages beasts, making them unable to distinguish friend from foe.

When used on Monkeys, Wolves, and Dogs, it will cause them to attack anyone in sight. It can be used to distract normal enemies in the same way as a Ceramic Shard. The final upgrade to the Finger Whistle, Malcontent, can be used to great effect on Headless, stunning the corrupted soul long enough to dispel the restricting mist surrounding it. Beware, however, that on the third stun Headless will violently slam it’s sword down, and the stun will no longer be effective. You can also use the upgraded whistle on the Demon of Hatred to basically take down 1 health bar if you wish to.

Slender Finger – The only Slender Finger in the game is dropped by the Guardian Ape boss upon defeat. You receive it once you take out both phases of the Guardian Ape, even the Headless version.

Conclusion

In conclusion, Sekiro: Shadows DIe Twice is a massive game that you have to put a lot of time into if you want to get everything in the game. To get 100% achievements, you are going to have to play the game at least 4 times on the same Save File. The achievements are not easy, but if you know what you are doing, then you will not have that bad of a time. The first playthrough is always the longest but once you understand how everything works, then there will be no issue. Have fun and make sure you don’t rage. Be patient, and you will have a better time in the end.
