100% Collection Guide
By iversiafanatic and 1 collaborators
Guide with all the collection items and their locations and prerequisites. Also some lore included in the spoilers!


Original info gotten from the chinese guide written by 这一看就是混血臭鼬. Without your excellent wiki, this wouldn't be possible. I am just translating your words with google translate, finding the game objects myself, and writing the descriptions. But I have had to borrow some of your images for now because I work on top of this, I am so sorry. Thank you for your hard work. I am just putting this out so more english people buy the game!

What even are these?
The collection items are objects you can pick up in each stage that have story relevance to the playable characters. Each character comes from a different associated level, and each level has fallen to chaos in some way. Most of getting the collectables is helping the characters learn more about their fallen worlds turning into abysses, so I've broken them up via zone/character. This guide will have spoilers for the abysses and characters.
Zone 1 (Hell Surface)
Ruby Crown Thorn

Requirements: None
Location: In magma at the lower left of Zone 1.

Zone 2 (City of Gold)
KR-965

Prerequirements: Using the character "Welles," play at least one game. On reentering the bar, a conversation will trigger with the butler about recovering the lost element columbium- the thing that made humans advance so far in the first place in the City of Gold, and the thing that lead to their civilization's collapse. After this dialogue, you can pick up the artifact with any character to the upper left of the start.
Location:

Zone 3 (Evernight Marsh)
Book of Truth

Prerequirements: This is the longest one. After a long dialogue tree with Asia about first, her home planet, then her realizing the marsh swamp is her home, then her asking you to find her book WITHOUT READING IT!, you can find the book at the upper left of the starting area, in the marsh with the huge tentacles. (It's best to pick this up with Asia, as the tentacles don't attack her.)

Zone 4 (Inner World)
Collapse Countdown

Prerequisite: This is part of the questline to unlock the hidden character Rozena. Her questline is really good, so please try to figure it out with the hint that she looks exactly like the broken shop doll, and she has a bell on her head!
How to unlock: After purchasing and refining the bell once, you can get some unique dialogue with every person in the bar about the mysterious doll and the power of the bell. Then, you can go pick up this artifact in Zone 4 in the upper right of the world with any character. This one's kind of annoying to get to, as it's far away and there's a lot of twists and turns.

Zone 5 (Asteroid Base)
Astronaut Helmet

Prerequisites: After a couple conversations with IAA about how her human colony was chased from planet to planet after being hunted by bug aliens, and how she's apparently lost someone precious she was looking for on her planet, you can find this at the spawn point for all the alien bosses that spawn from this level, I think. It's to the left and down of the spawn point.

Zone 6 (Fruit Planet)
I am borrowing 100% of these annotated images from this quite frankly better chinese guide, so check it out. But it's not in english (though the writer has expressed they want more English information out there, which is why I'm posting this!) so here's the literal translation.

Ninja Certificate

Description: Made of precious oak, the wood grain twists and turns around, symbolizing the ups and downs of life. After decoration, as a graduation certificate of the Ninja School, it is presented to the best student. On the top of it, the school motto is engraved: "Revere death."

Prerequisites: After a few conversations with the character "Little Sara" about how her planet was destroyed by the exploding of the red sun, and how she's worried about her prince. She says she won't worry about it and that soon everyone will be able to eat the fruit salad she's made. Then, you can find it in the upper right corner from the start point.

Thank you for your information. But I'm still not able to locate the collectible in zone 1. Tried a couple of times to the lower left direction but couldn't find it. Is there any exact location or coordinates?

scar i can tell youre not that intelligent since you use the word "waifu" unironically so it makes sense you had trouble getting that one, especially if you were purposely avoiding parts of the game since you were too horny to pay attention

After reading the lore, City of Gold is indeed Welles area. He was part of a team there and got wiped out by some space tumours hitting the planet.

Also btw I'm like 99.9% sure I got Inner World's artifact (pocket watch for Rozena) BEFORE i ever unlocked The Bell, so you don't need to have The Bell or start Rozena's questline in order to get the pocket watch, so I'm pretty sure there are no prerequisites to obtain it.

(In case you wonder why I'm so sure: the pocket watch was definitely my first artifact I got and I'm sure I didn't have The Bell unlocked yet because I'm a maniac and I unlocked all statue upgrades before unlocking any weapons or characters AND for some reason I assumed that when you unlock Rozena you'll get The Bell for free, so in order to save 20k coins or whatever I unknowingly kept myself from unlocking my favorite character at the time for like a week lol, so by the time I bought The Bell/started Rozena's questline I believe I had at least the pocket watch, the astronaut helmet and the crown)

"Zone 2 (City of Gold) KR-965 - Prerequisites: Play one game as Welles" bruh... really devs? Isn't City of Gold Zelde's map?

After 105 hours of playtime, easily getting every other artifact and 63 City of Gold runs looking for this artifact I finally decided to look for hints... I would have never figured this out since I never planned to play Welles or any other male character in my waifu game xdd

Thanks mikescubes!

Awesome thanks for the update!

Sorry, I don't know how to link back to your comment on steam, Arevi. No, you don't have to play as the relevant character for any of these. I wasn't sure for the graduation certificate but I picked it up today and can confirm none of these are character-locked.

Quick question, do i have to play as the relevant character on that stage or will the item appear as long as the other requirements are met?
