Item Location Guide

Where to get each item (excluding ones that are bought and equipables)

Introduction

I found myself googling time and tme again where to get the indegrient for a synthesis and stuff like this, so I decided to make a list myself.
I put way too much work into this. Like.. I wrote a 400 line program to parse the game files, wrote item drop locations and synthesis collections myself and brooded over the game files for literally days. Bit ashamed that all I got out of it is this rather short list

Ending words

I initially intended to add the locations of the enemies.
But I brooded over the game files for literally a whole day and I can't figure it out.
Do me a solid and at least upvote this guide because I sunk way too much time into it without getting anything out. I'm not even kidding, I looked at the game's JSONs for hours, googled anyone that may have an answer, all for nothing.

If you want to try your hand at it, I can share where I ultimatively gave up:
The game data is in Install dir/www/data
The enemies itself are in Enemies.json. Enemies in RPGMaker seem to be collected into Troops (Troops.json), each battle seems to be against such troops, not enemies themselves.
From an old tutorial I found, on-map battles (as opposed to random encounters) seem to be Events.
Now.. Sewer Entrance is a small map. All you fight are troops of single slimes. The Slime enemy has the ID 41, the only troop where there's just a single slime is troop id 23. The Map is Map099.json.
But for the life of me I can't figure out how any of the events etc of that map connect to troop 23 or enemy 41.
(Additional, on map 208 (TV Tower), there should be troops 174 (Hell's eye, Siren), 169 (Siren alone), 165 (Agitator alone) and 171 (Enigma alone). Still couldn't find any connection myself, but that may help you intrepid puzzle solver)

I don't remember "id180". if you mean item id 180, that would be the lucky jar, that one you can buy at the shirne maiden in the subway/train station, as far as I remember

[Fexlirey]

Hi, how i can find item id180? This item for craft Box Of Waking

[JPX]

Yes, it's a battle only power up.

[Akhlys]

JPX, Don't remember clearly but I thought it was a consumeable

[JPX]

Well done!
What about 'Power Apple'? Found it in school dungeon lockbox, can't use it. Supposed to give all stats+.

[WomboCombo]

that Warped Mutated Metal takes forever to farm.
but thanks to you, at least that is feasible.

[Exynos]

Thank you for this

[Ultimate Despair]

You get shadow ring from the treasure behind Mother Blob.

[Akhlys]

If it's not on the list, it's probably from one of the shops. This one tho, according to the sheet afrowhitey linked, it's dropped by Mother Blob, the hidden Boss in factory ruins, go here https://drive.google.com/file/d/1UZWfrwEgzz0_6ZhJo2qPc2QpJAorlo3L/view

Also, thanks for the guide.
