The guide covers how to obtain (almost) all outfits, as well as our current discovery on the contents starting with the Engram Lodestone obtained randomly in battles. The latter actually leads to quite substantial end-game contents, and you might consider trying to figure things out yourself before looking at what the fans have discovered so far.

Note: You would need strong enough spirits to get past some of these

1. Obtain Engram Lodestone
   
   • They seem to have even lower drop rate than Spirit Egg & Moonstone, around 5% from my experience, and I don't know whether there is a way to increase it
     
   • Unlike with Evo Stones, fighting high-level Spirits doesn't seem to increase the odds
2. Farm more of these, you need 9 in total. It's recommended to:
   
   • Use a strong Spirit (e.g. Fire) to quickly finish low-level encounter with only 1 card
     
   • Extend length of a day by changing the game's setting
     
   • Increase spawn rate by changing the game's setting
     
   • Increase spawn rate by consuming Spirit Scented-soup
     
   • Increase spawn rate by dropping a crop on ground (?)
3. Go to Dark Island to fish with the Lodestone equipped for Engram Dust
   
   • You can fish inside an upgraded Greenhouse regardless of season
4. Feed it to Spirits in barn for Void Stone Ore
   
   • Do NOT feed multiple to the same Spirit
5. Smelt all in furnance into 1 Void Steel Ingot per 3 ore
   
6. Place the 3 ingots onto the gound of Tavern's basement for The Half-horned Crown
   
7. Go to the Spring Temple's island at night
   
   • Around the base of one pillar, you can see a faint glow around it
     
   • Craft Sigil Chalk in the Moonstone Enchanter
     
   • Place it in the 6 corresponding spots around the pillar
8. This opens up a new dungeon... prepared for end-game level Spirits!
   
   • Dungeon contains many block-pushing puzzles
     
   • As with other dungeons, you can use Balloon to fly over gaps, but that's kinda cheating so don't do that
     
   • You can technically skip the entire dungeon by walking behind the barrel on the west, then keep walking to the north-west direction through the hidden path
9. Reach the end of the dungeon, then interact with the weird tree to be teleported
   
   • On the right is a wall mural with music notes. Play the Warp Whistle here (RIP Toxitoe)
     
   • On the left is what seems to be an ARG (Alternate Reality Game), which the community is still trying to figure out its purpose...
     https://www.moonstoneisland.com/soonmymetronome
10. Select the The Half-horned Crown and place it onto the statue
    
    • Proceed for a very difficult boss fight
      
    • The builds showcased in my combat guide should still work, but you are very likely to be outsped by the boss. Thus, you want to be able to tank some hits before being able to unload your damage
      https://gtm.steamproxy.vip/sharedfiles/filedetails/?id=3362578279
11. Afterwards, you obtain the ???, an egg that hatches into the Tollsbell
    
    • It is a "one-of-a-kind" Spirit, and cannot be holographic
      
    • Its ability is a lesser version to the boss you've fought. So basically it copies half the enemy's buff to itself, and copies half the received debuff to its enemy
      
    • It is a dual-type of Dark & Psychic, so if you don't like Darkitten's ability, you may consider using Tollsbell instead
12. Go to the URL in step 9
    
    • [Right-click] the image, then click "Inspect"
      
    • Press [delete] on your keyboard to reveal a small browser game
      
    • Walk in the south-south-west direction, and pay close attention to the audio, the faint music would get louder as you go closer to the mysterious structure
      - Exact location is 15-screen-south and 7-screen-west
      
    • A sound would play at a certain tile, with a silhouette of a person being visible. Press [X] or [SPACE] to interact
      
    • Whether you response with "Yes" or "No", a weird symbol that has 3 overlapping ∆ would appear, with the word T.O.W.E.R shown below it
13. (We are still figuring what's next... so join the Discord server for latest discovery!)

For the puzzles, you can skip the dungeon with the aforementioned hidden path, but I might a video if enough people ask for it.

As for the boss fight, there are many ways you can win, but here is a wacky strategy with solo Dreamy. Do note that you want to be bring along a Intangible Cleanse Potion for this strategy though.

(At the end of the dungeon, a note reads as follows)

I've done it. After picking away at the seams of this world and peering through its gaps, it's become clear to me what this is. It's a comforting distraction, a play set on a stage-a world inside a T.O.W.E.R. One of many.

I do not know the purpose of these places, but I've found a way to another. And though the only Universal Key I could uncover was the letter S, I still hope to find more there.

But I may need your help.

If I don't return, you can always find me in the files.

Wish me luck, dear friend.

(Upon interacting with the silhouette in step 12, this is what he says)

You.
You come from a Tower I no longer recognize.
Though, I still think of it fondly.
I used to run a tavern there.
I think.
But then I discovered something.
Something hidden deep.
Something I’m still not sure I was supposed to find.
I couldn’t keep going after that.
Pretending everything was okay.
I had to follow her to where she would lead me.
Even though I can no longer exist there, seeing you here fills me with immense gratitude.
It is incredible that you have found me.
It makes me think this just might work.
One day I will offer to take you somewhere else.
Somewhere very different.
If you trust me…
We can find meaning in this different place, just as we did in the TOWER from which you came.
Do you trust me?

Then you will likely follow her one day too.
If you do, don’t forget, no matter how much she tries to make you, no matter how much she insists on her hierarchy…
This TOWER is a field.
We are all on the same floor.
No one sits above another.
Now I must remove you from this place so they may continue to build their TOWER here.
But keep watch.
Other TOWERs will appear before hers can be accessed.
They all hold meaning and will help when she comes for you.
Finally…
Keep an eye on Tollsbell.
One day she will hold a Key.
Do not be Idle, friend.
Goodbye

I understand your hesitation
Trust is not something given lightly.
Perhaps in time, this will change.
For now, know that the TOWER will be built.
And when that time comes, the choice to enter will be yours.
Do not be Idle, friend.
Goodbye.
