There are a lot of spells. There is a game mechanic to have only one shown at a time, and only certain spells at that.
How do you remember/lookup all the other spells? Do you have to find a list online and print them out? Is there a standard rule for how they are 'built' so you can easily 'create' them on the fly if you know the rule system? The rule system they lay out in the short tutorial at the beginning that throws a lot at you at once was confusing, so it wasn't very helpful (for me). Did I miss something that should make this easier?
