Nexus+Titansouls
Welcome to Magical Nexus!
Magical Nexus is the home for all of the monsters created by the Stair Shaper! This includes all magicals from the magical islands (Light, Psychic, Faerie, and Bone).
Getting started
Magical Nexus is not a hard island mechanic wise. To fill the collection book you Transpose monsters from the 4 main magical islands. But what is transposing? Transposing is basically the same as saying teleport, just for islands in the beyond. To transpose monsters, they must be level 18, and you will have to pay a cost alongside it. For common monsters you have to pay coins, and for rares/epics you must pay diamonds. The cost varies depends on element count as well. Below is a table with the cost to feed 1 monster of each element count to 18, as well as a transposition cost. Also includes values for all monsters within the collection. There are 4 singles, 12 doubles, 12 triples, and 4 quads in each rarity.
Single Elements: 
2,990,040 per 1
11,960,160 for 4

The treat amount is the same for each rarity.
Teleporting monsters to nexus doesnt just build the song, but builds a special structure called the Nexus Nucleus. The Nexus Nucleus gives you rewards based on how many collections you have filled. The more collections, the better the rewards! There are 4 collections per rarity, for a total of 12.
As shown above, there is a single, double, triple, and quad collection for each rarity. These will fill up as you fill your collection book and will be completed once you have all monsters of that element count.
Nucleus Rewards 
The Nucleus gives rewards that scale with your progression. Below is a list of each completed collection count, with the rewards it gives.

Chart taken from the wiki
These rewards do take a lot of food and resources. it takes
125,581,680 for all 32 monsters per rarity. Below is a list of coins/diamonds in total you'll need to max out 4 collections for each rarity:
Commons:
108,000,000
Rares:
540
Epics:
1,080
The Epic Magicals are not complete yet, so we do not know all of the rewards.
Titansouls
Titansouls are strange beings hosted only on the magical islands, that are unlocked after the Earth Island colossal conundrum is complete. They may be purchased in the market for
10,000,000 coins, but cannot be sold.
Mechanics
Titansouls are activated by linking monsters and using soul'er power. Soul'er power draws coin production from monsters to fill the titansoul! The higher coin production, the higher the power! You're allowed to link 4 monsters of each rarity that are unique, and not dipsters. This means once you have a mammott linked for example, you cannot link another mammott of that rarity.
Coin productions are effected by levels and happiness. You'll want to make sure your monsters coin production per minute is high to get more power!
The more Soul'er power you have, the better rewards that generates, and the more it contributes to the song. A titansoul can generate shards, breeding boosts, incubation boosts, baking boosts, or costume boosts. The 4 squares in the middle track Soul'er power, and once all are filled you will unlock all tracks the titansoul has to offer! Upon linking 12 monsters to the titansoul, the titan will awaken! Note, even if you link all 12 monsters to the titansoul it still might not have enough Soul'er power to play all of its tracks. Make sure you pay attention to the progress bar in the middle! Each full square is a track unlocked. All 4 being full means all 4 tracks!
Farming 
We can take Soul'er power to another level though. Soul'er power keeps adding on even if the bar is full! We already know that a titansoul can generate shards, and the more Soul'er power we have the better rewards we get, so lets stack those together!
You will have to sacrifice a LOT of coin production to achieve good shard production, but in doing so you can gain hundreds of thousands more each week! If you're a dedicated collector, you can net an extra ~2m shards per week if all are level 20, 100% happiness, and you use the mirror islands. Below is a list of monsters to link to your titansoul for the best shard output!

Rare and Epic Paironormals will replace the rare magical quads and epic triples, but they have not released as of now. Be sure to collect your titansoul boosts often enough, as while they're available that monster will not be able to produce shards.
