The guide covers most of the new features from the latest Evolution update. Reference tables are also attached listing all the new Spirits' abilities, or you can read them on the Wiki pages too:

• New Ability - https://moonstoneisland.wiki.gg/wiki/Spirits
  
• Summary - https://moonstoneisland.wiki.gg/wiki/Evo_Stone

To evolve a Spirit, first find an Evo Stone from defeating high-level psychic Spirit, then read the letter on the next day to accept a quest. From there, train any of the applicable Spirits to at least lv32, at which point their Evo meter would show up, which upon filled lets the Spirit evolve.

• As of writing, only 30 out of the 88 Spirits have an evolved form
  
  • All other Spirits are unable to evolve
• The following critiera have to be met before a Spirit can evolve
  
  • Obtain your first Evo Stone
    
  • Receive the letter on the next day's morning
    
  • Applicable Spirit is at least level 32
    
  • Applicable Spirit has accumulated 1000 "evolution points" after hitting level 32
    - 15 points are gained each time a battle is completed
    - 5 points are gained each time a card is used from that specific Spirit's deck
    - No point would be gained at all, if you flee the battle
    
  • When all critiera are met, you can choose to evolve through menu
• Evolved Spirit gains an additional type, allowing them to get cards from that type
  
  • This can further compact your team, making 2-spirit or even 1-spirit teams more vaiable
    
  • There is a total of 28 combinations of typing, each represented by at least 1 Spirit
    - (see reference table at the bottom)
• Evolved Spirit replaces their original 2 weaknesses with their new type's weakness
  
  • This means when Dusty evolves to gain a new Fire type, it now becomes weak to only Water, regardless of its original weakness
• Evolved Spirit gains an additional ability
  
  • Armbot evolves into Digbot, which is required to unlock Deep Mine
    
  • Reward of Deep Mine is a new boss fight and a decorative furniture item
    
  • Deep Mine in my game has a bug that prevents me to do anything after the first wave. My solution is to use keyboard control instead of the mouse for the final click (i.e. final action that defeats the final enemy)
    - (or hold the "next turn" button prompt at bottom-right to skip a turn)
    
  • It does seem the original ability is gone upon evolving... RIP my solo Dusty build

1. Evo Stone is obtained from defeating high-level Psychic-type Spirit
   
2. Go to any high-level island, e.g. the Dark islands through the mirror
   
3. Ready a Psychic Sight Potion
   
4. Save the game at 19:50
   
5. Use the potion as soon as the clock hits 20:00
   
6. If the Pyschic Storm does not appear in a high-level island, reload and repeat
   
7. Keep hunting Psychic-type Spirit until you're out of time
   
8. Here are some more tips
   
   • Change settings and/or bring along Evileye to increase spawn rate
     
   • Change settings and/or use a Time Dilation Potion to farm for longer
     
   • Use a Night Vision Potion to see
     
   • Save after getting each Evo Stone for easy reloading
     
   • Bring along a tent if you want to stay up until the last minute without fainting
     
   • The evolved Shrubbin has the ability to give Evo Stone too, but the rate is too low to worth explicitly going after
9. The dev also revealed more info in this reddit post
   
   • Evo Stones have a rarity of 2%-50%
     
   • Drop rate scales with enemy level. 2% for levels 1-5, 50% for 55+
     
   • Hunting on ring 5 islands gives you best drop rates
     
   • There's also a guaranteed drop starting from Fall 1 if you haven't found a stone yet

Basically you just find a random Spirit, and use any card 200 times from the deck of whichever Spirit you are training for. It's easier to bring along a Psychic Spirit or two just so you have practically unlimited energy, then it's just a matter of spamming the same Bash over and over again.

1. Include a Psychic-type Spirits in your party
   
   • It's recommended to reset the deck of your trainee Spirit
2. Enter any battle
   
3. Reach 99 energy with Psychic cards:
   
   • Open Mind+ - Gain 2 energy
     
   • Mind's Eye - Gain 10 energy
     
   • Enlighten+ - Triple your energy
4. Use any card from the trainee Spirit for about 200 times
   
   1. You may use Bash 99 times before finishing the battle, and then repeat this step in another encounter; or
      
   2. You may use Bash 50 times before getting back to 99 energy with Enlighten+, repeat, then use Bash 99 times again within the same battle. This does require more copies Enlighten+ or a Deja Vu+ card, so it might be less preferred
5. Finish the fight either by defeating or capturing your foes, do NOT flee!

I recommend using a 2-spirit team, where you pair your trainee Spirit with a supporting Spirit using either of the listed loadouts. The role of the supporting Spirit is to give you 99 energy, so it doesn't need to be very complicated as long as it allows the trainee Spirit to play its cards many times.

Alternatively, a commenter has pointed out that the following setup would work too.


The idea is to use a 1-Spirit team that has at least 2 Graverobber+ cards, which allows you to loop between each other, so long as you can draw them within the first time. For reference, it is a 0-cost card that returns a previously played back to your hand.

I personally don't prefer this method as much mainly because it's more difficult to keep track of how many cards have already been played. Not to mention for each Spirit you are training, you would need to put at least 2 Graverobber+ cards into its deck (and likely have to cleanse afterwards.)

Maybe some of you would prefer this method? I just personally find it more convenient to train using a support Spirit instead.

• As mentioned earlier, you need to evolve Armbot before Deep Mines becomes accessible
  
• The way whether a Deep Mine would appear seems to be seeded for order of discovery
  
  • This effectively means saving and reloading has no effect on discovering Deep Mine
    
  • Doesn't matter whether the evolved Spirit is with you at the moment the sinkhole appears, you can return at any point to check without affecting whether Deep Mine would appear
    
  • Doesn't matter which island the sinkhole is on. So if you save before finding a sinkhole that you already know would contain a Deep Mine, you can reload and open a new sinkhole on a different island - This new sinkhole would still contain a Deep Mine
    
  • It's also somewhat difficult to keep track of whether you've already checked if the sinkhole contains a Deep Mine or not
• I recommend keep bashing rocks to discover sinkholes in order to find Deep Mine efficiently
  
  • Travel with Barkbyte (or its evolved form) for extra sinkhole per island
• Inside the Deep Mine you can is a mini-boss fight
  
  • The battle is in 3 waves, and fleeing at any moment would not save the progress, meaning you would need to restart from the 1st wave
    
  • The 1st and 2nd waves each consists of three random enemies (same type as island)
    
  • The 3rd wave has you fight against a mini-boss called Delver, which looks similar to a Dungeon Guardian. It always moves first, and has an ability that would banaish a random Spirit in your team if you have a full team of 3 Spirits
    - This may make a 1-Spirit or 2-Spirit team more preferrable here
• Your reward is a Boss Chest containing a random variant of Cave Crystal. (furniture)
  To efficiently hunt for a specific one, you can:
  
  1. Fina a new sinkhole, then save BEFORE entering
     
  2. If the sinkhole does not contain a Deep Mine, go back to step 1
     
  3. Look for the Deep Mine entrance in this sinkhole. You can always reload to the previous save if you don't like the current layout, and ideally you want the entrance to be within a few seconds of walking distance from the ladder
     (In the screenshot below, you can see the entrance right by the ladder, lucky!)
     
  4. As for the Deep Mine layout itself, I don't think it can be rerolled however
     
  5. Anyway, defeat the miniboss as normal, then save BEFORE opening the chest
     
  6. Open the chest, and reload it's not what you're looking for to reroll the reward

While the new evolution mechanics does not affect my already perfected Electric solo team, it does allow for some interesting spirit combo. Notably for 1-spirit teams, a Psychic-Dark would provide truly infinite energy, whereas a Fire-Psychic would allow for using Explode repeatedly while Intangible. (i.e. taking only 1 damage)

You can read more about these in my new combat guide:

That's about it! Special thanks to the people sharing their founding in the official Discord server and wiki. And if you find this guide help, give it a thumbs' up so more people may see it!

There is usually 1 Spirit available for each possible type combination.
(Ankylo and Capacibee were added in a separate version update)


Say you want see what all the new Electric Spirits are using this table, you would start by looking at the Electric row from Armbot and go right, then turns 90˚ at the Electric column down into Breadmaus.
e.g. [Electric] Armbot -> Claudio -> Ribbite -> Breadmaus -> Burgloon -> Beardini -> Barkbyte

I also put together a compendium that contains a wide variety of info tidied neatly into spreadsheet format. The Page Index is in the Steam Guide, so you might find it useful for navigating the spreadsheet.
