Magical Sanctum
Welcome to Magical Sanctum!
Before anything, to start working on this island you must have at least 2 different single element Magicals. This includes the following: 
Fluoress, 
Theremind, 
Floot Fly, and 
Clackula. They may be teleported to the island at level 15, which costs exactly (per monster) 
655,320 treats. All 4 of these magicals can be bought with 
Coins on their respective magical island.
Populating the island 
Once you've teleported two different single element Magicals, the breeding can commence! This works like standard breeding, as you've encountered on many other islands. While Sanctum isnt as hard as Ethereal, the monsters wont come to you easy. It will take a little bit of effort to complete the island!
Farming 
Farming on magical sanctum is quite simple, and ranges from how far you are in the game. The main difference being variants! For early game players, it is best to just spam any single element magicals wherever you can. There are advanced ways to shape these monsters, however.

The grid shown above would be the most grid efficent way to put monsters. To start, its best to fill these slots with as many magical singles as you can. As you progress, you'll want higher castle tiers and 
rare/
epic monsters! Clackula would be best for this, as it only takes up a single grid space and is easy to spam. For more advanced methods, you may start adding in 
Carillong, and working your way up with the variants of both!
