Moon: Moon is the polymorphing school! You remember how you can buy transformation elixirs at the crown shop? Moon takes this to the next level. Not only do you get the appearance of the creature you polymorph into, but you get a deck that the creature would get!
Star: You casted a global, but the enemies use it too! DARN! You have a blade, but the enemy steals it! DARN! No more darns! Star school is all about auras. Auras are rings of magical energy that glow around you during a battle for a few rounds. What they do varies on the color. Some are for defense, while others are for precision or attacking.
Sun: What's going on? Why isn't anyone casting sun spells? You see, you can't see sun spells, you experience them. You know those spells like weakness, tough and their advanced versions? well, now they have a home! Or, a school, I guess.
Remember, you have to be at least level 50 and have access to CL to learn these new spells. The school trainers are located in the CL Base camp. Enjoy!
