NieR Replicant ver.1.22474487139...

Alrighty, strap in friends. This is gonna be a long one...

I would save this achievement until completing Ending E, making it one of the last achievements you’ll need. If you don’t rush through through the game and collect all items you come across as well as fight all shades you run into, hopefully you’ll have naturally acquired many of the materials needed.

There are 30 weapons in the base game, 3 weapons from “The World of Recycled Vessel” DLC, 4 weapons from the “YoHRa” DLC, and 1 Secret weapon. How to obtain the Secret weapon... This makes 38 weapons total. Only 33 of the 38 are required for this achievement so you will have 5 weapons you can skip upgrading altogether. Choose wisely based on your inventory.

I recommend including the Secret weapon in the 33 needed since it requires very common materials to fully upgrade and it will help you when farming the other materials you need. . I would also recommend upgrading the 4 “YoHRa” DLC weapons because they are fairly easy to upgraded as well (especially compared to some of the other weapons). If you choose to upgrade the Secret and “YoHRa” DLC weapons you will be able to skip upgrading 5 of the base game weapons of your choice. The 5 best weapons to skip will be different for everyone depending on the materials that have been picked up, but generally the Pheonix Sword and the Iron Will are ones that requires many rare materials. The Iron Pipe, Sunrise, and Axe of Beheading are also good choices to skip, depending on your inventory, of course.

Now for the list...this is all weapons, along with all materials and how many of each material you need total to fully upgrade each weapon.

And finally, here is a list I’ve compiled of all the raw materials needed to upgrade every weapon in the game (including the “YoRHa” DLC, “The World of Recycled Vessel” DLC, and the Secret weapon), along with how many of each material needed and their locations ⤵️

NOTE: If you’re about to rip your hair out grinding,I’d recommend trying out the auto-battle feature, which makes grinding much quicker and easier. However, this feature can only be utilized on Easy difficulty.

Another thing you can try, that’s worth noting, is setting the game’s difficulty to Hard. It’s officially been confirmed that rare drops and the overall RNG is better on Hard difficulty.

If you’re well equipped and (on Hard difficulty) taking down enemies quickly with ease then farming on Hard is what I’d recommend.

If it’s difficult and taking you a considerable amount of time running through the enemy spawn points you’re farming, then I’d say it’s best to set the game on Easy difficulty and take advantage of the auto-battle feature. At least until you’re better equipped to handle the game on Hard difficulty (if you’re still needing materials by then, of course).

Also, make sure to equip the “Mahzarken” Word on your magic and weapons when collecting all these materials. This will give a +30% item drop rate boost. This probably doesn’t effect ALL the material drop rates (not sure if it effects crates), but may as well play it safe and keep “Mahzarken” equipped til you’re done farming. If you do not have the “Mahzarken” Word yet see the Forlorn Necklace location below for how to obtain it.

•Amber [14] –
1} Purchase at the Material Shop in Facade for 6,000 gold.
2} B2 in the Junk Heap crate room (far north on first B2 map). Once you’re done breaking all the crates in this room, drop down into one of the openings in the floor until you die. This will reset the crates and put you back at the start of this room.
3} “The World of Recycled Vessel” DLC crate room (3rd door on the far right when facing all 3 doors). Once you get to the crate room (which resembles the underground lab), keep going until you come to a bridge. If you do not care about the experience or the 50,000 gold you get for finishing the 2 maps after this then after smashing all the crates on the bridge, jump off over and over until you die for good and start again.

•Black Pearl [15] –
1} Gathering spots on the 2 beaches in Seafront. One beach is right next to the fisherman npc (who gives you “The Fisherman’s Gambit” side quests), and the other is through the short tunnel you take to get to the lighthouse.

•Broken Antenna [37] –
1} Common drop from regular robots on any of the Junk Heap floors.

•Broken Arm [49] –
1} Common drop from regular robots on any of the Junk Heap floors.

•Broken Battery [5] –
1} Common drop from flying robots on floors 1F and B2 in the Junk Heap.

Broken Earring [4] –
1} Rare drop from “Shaman” Shades. These are the ones that are Nier’s size that shoot orbs. There are 2 that spawn on top of the Lost Shrine (after all fragments have been collected). When looking straight ahead at the save point next to the boss door look to your left to see a ladder. Climb it and the second one you come to after the first. At the top (straight ahead) is where they will spawn (this is also where you can get the “Mahzarken” Word that gives +30% item drop rate boost). To reset the spawn simply drop back down to the boss door, next to the save point, and enter then exit back out and climb the ladders again.
2} Shaman shades also spawn in the Northern Plains (after getting the Forest of Myth fragment). Best way to farm here is to ride the boar (after “Boar Hunt” side quest) around the Plains during sunny weather and watch for them to spawn. If you need to change the weather to sunny, keep entering and leaving the Forest of Myth until it changes. You’ll know you have it right when you enter the Northern Plains from the Forest of Myth and see a Shade shooting orbs around straight ahead. To reset the spawns you don’t have to leave the map and you shouldn’t if you can avoid it because it could change the weather. Instead, ride the boar to a npc standing nearby (if you enter the Northern Plains from Nier’s village make a sharp right and follow the wall on your right hand side until you run into him) and start the mini game. As soon as it starts you’ll be on a boar. Simply jump off to stop the game and reset the spawns on the map without changing the weather. There are 6 total Shaman Shade spawn spots on the map but they are all pretty spaced out. The boar helps with this but I find that the first method is the quickest and easiest.

•Broken Lens [5] –
1} Purchase at Two Bros. Weaponry for 900 gold.
2} Drop from regular robots on any floor in the Junk Heap.

•Broken Motor [11] –
1} Common drop from flying robots on floors 1F land B2 in the Junk Heap.

•Broken Pottery [2] –
1} Rare spawn from gathering spots in Northern Plains and The Aerie.

•Broken Saw [5] –
1} Rare drop from the small, armored Shades in the Northern Plains.

•Broken Wristwatch [11] –
1} Rare drop from the large, armored Shades in the Southern Plains. More will spawn during sunny weather. To change the weather here enter and leave Seafront until it’s sunny.

•Clay [18] –
1} Purchase at the Material Shop in Facade for 800 gold.

•Complex Machine [8] -
1} Random drop from Boss Shades (the big ones). These can spawn randomly in many places but are far and few between when trying to farm. Instead, I recommend replaying Nier’s Dream from “The Magic Stone” side quest over and over since it sends you to the Intro of the game and always ends in a Boss Shade fight. “The Magic Stone” side quest is given from the fortune teller in the Forest of Myth (must have all fragments).

•Copper Ore [88] –
1} Purchase at Two Bros. Weaponry for 480 gold.

•Crystal [16] –
1} Purchase at Material Shop in Facade for 2,400 gold.
2} “The World of Recycled Vessel” DLC crate room (see Amber #3 solution above for more details).

•Damascus Steel [9] –
1} B2 in the Junk Heap crate room (see Amber #2 solution above for more details).
2} “The World of Recycled Vessel” DLC crate room (see Amber #3 solution above for more details).

•Dented Metal Bat [21] –
1} Rare drop from small Shades in Northern Plains or Underground Laboratory in Emil’s Manor.

•Dented Metal Board [9] -
1} Purchased at Junk Heap from Gideon for 750 gold.

•Eagle Egg [4] –
1} “The World of Recycled Vessel” DLC crate room (see Amber #3 solution above for more details).
2} Rare spawn from gathering spot in The Aerie. The spot where it spawn is directly under the Chief’s house. Save at the save point when you enter The Aerie and take the bridge to the first platform here. Angle the camera so you can see if the gathering spot has spawned before you get to the ladder. If not, quit and reload your save. If it spawns then you’ll have to finish crossing the bridge to get to the ladder, climb up, run across the upper bridge, and jump down to it. If it’s not the Eagle Egg then quit, reload and repeat until it is. NOTE: Check the gathering spots by the save point each run. Sometimes Moldavite or Meteorite will spawn here.

•Elaborate Machine [5] –
1} Random drop from Boss Shades (see Complex Machine solution above for more details).

•Fluorite [18] –
1} B2 in the Junk Heap crate room (seen Amber #2 solution above for more details).
2} “The World of Recycled Vessel” DLC crate room (see Amber #3 solution above for more details).

•Forlorn Necklace [4] –
1} Rare drop from “Shaman” Shades (see Broken Earrings solution above for more details).

•Giant Egg [6] –
1} Rare spawn from gathering spots around Nier’s Village.

•Goat Hide [4] -
1} Picked up off the bodies of slain goats.

•Gold Ore [24] –
1} “The World of Recycled Vessel” DLC crate room (see Amber #3 solution above for more details).
2} Rare spawn from gathering points in the Desert, Barren Temple, or The Aerie.

•Iron Ore [263] –
1} Purchase at Two Bros. Weaponry for 1,000 gold.
2} Random spawn from any gathering spot.

•Large Gear [7] –
1} Rare drop from regular robots on any floor in the Junk Heap.

•Machine Oil [5] –
1} Rare drop from flying robots on floors 1F and B2 of the Junk Heap.

•Memory Alloy [14] –
1} Rare drop from P-32 robots (big ones) in the Junk Heap. There are 3 that spawn on B2. 1 is on the first map after you run thru the crate room in the northern most part of the map. The other 2 are on the second map of B2 in the large rooms. You have to go outside and re-enter to reset the spawns here.

•Metal Piercing [4] –
1} Rare drop from flying Shades in Desert (must have the Facade fragment for them to spawn). This is one of the hardest farms in the game since the flying Shades only spawn 1 at a time. There are 3 spots on the map that they can spawn. One is right after you walk up the steps from the fast travel dock (on a small sand hill), another is West of the Facade entrance (again, on a hill), and the last one is in the sandstorm area (you will see this one on your map). This is also how you farm the Subdued Bracelet. You should get the Metal Piercings you need well before the Subdued Bracelets.

•Meteorite [5] –
1} “The World of Recycled Vessel” DLC crate room (see Amber #3 solution above for more details).
2} Rare spawn from gathering spots in the Desert, Barren Temple or The Aerie.

•Moldavite [12] –
1} Purchase at the Material Shop in Seafront for 8,000 gold.
2} “The World of Recycled Vessel” DLC crate room (see Amber #3 solution above for more details).

2} Gathering spots on the beaches in Seafront (during Act 2 items don’t appear on the beaches until Louise is defeated and the big ship is gone).

•Pyrite [14] –
1} “The World of Recycled Vessel” DLC crate room (see Amber #3 solution above for more details).
2} Rare spawn from gathering points in the Desert or the Barren Temple.

•Rusted Clump [14] –
1} “The World of Recycled Vessel” DLC crate room (see Amber #3 solution above for more details).
2} Can be caught while fishing off the fast travel boat dock in the Desert using Lures and Sardines.

•Rusty Bucket [10] –
1} Can be caught while fishing in the Northern sand river in the Desert using Lures.

•Rusty Kitchen Knife [9] -
1} Can drop from enemies in Nier’s Dream (see Complex Machine solution above for more details).
2} Rare drop from small Shades in the Northern Plains.
3} Common drop in Act 1.

•Scorpion Claw [10] –
1} Common drop from scorpions in the Desert. Kill them and press “B” to pickup materials from the corpse. Scorpion locations are easily seen on the mini-map. Run near them to make them jump out and attack you (must kill the wolf Shade first).

1} Drops from flying machines in the Junk Heap (Part 2) on the first floor. *NOTE: You will need 10 of these for

Those are all the most important materials to farm for. If I missed any feel free to let me know and I’ll add them.


Hope this helps!

I will briefly share the things I really needed to get this achievement, it's all just farming mats. There are a few specific items which were tedious near the end which I will note here:

Black Pearl - drops on the beaches at Seaport. There will be 2 spawns beach next to the Fisherman and about 4-5 spawns in the shipwreck beach. Just rinse and repeat, I saved at Seaport and hop over the Postman and jump into the water, this lets me tp to the beach and skip walking there. You need 15 so prepare to spend about 15 minutes/Black Pearl doing this. Here is a video:

Forlorn Necklace/Broken Earrings - both of these drop from the Shaman shades at the top of the Lost Shrine. Save next to the door, and just keep re-entering the door after you wipe out the 3 mobs (there will be 3 shaman shades to kill per run). You technically don't need to reload the game to reset the mobs, just enter and exit the boss room.

Dented Metal Bats - you can get these elsewhere but you wanna farm these in Emil's mansion underground, there's a specific room (like a maze) where these shades will drop them at a reasonable rate.

Subdued Bracelet/Metal Piercing - you only get these from flying shades. I've gotten some from the Lost Shrine (but if you kill them when they're not over land you won't get the drop), but you want to farm these in the desert outside of Facade (there will be 3). I still haven't got my subdued bracelets but I've gotten a bunch of metal piercings, so the bracelets probably have a lower drop rate.

EDIT: I ended up getting my first Subdued Bracelet in the Shadowlord’s castle during the waltz, a wave of 6-7 flying shades will appear. Honestly resetting each playthrough to try and get at least 1 Subdued Bracelet here would save you any time farming these in the desert. My 2 cents.

Eagle Egg - if you already went to the Aerie and got the fragment, it's really not a big deal. You can farm these relatively easily in the Recycled Vessel diary (third door). It will be the third wave where you can break a bunch of boxes and the Eagle Egg has a chance to drop in them.

Broken Wristwatch - these weren't too bad I just didn't have much at the end of my playthrough so I had to farm a bit. These drop from the armored shades in Southern Plains.

Remember you don't need to upgrade every single weapon to unlock this achievement, after it popped I still had 3 weapons left to upgrade, most of them requiring subdued bracelets lol. Choose wisely.

Hope that helps anyone! :)
