I know this could be more complex, as spells can be heightened and some of them can be a preference at other levels than original, but I think its not enough useful as the complexity it would take.

As for previous responses from Arcane survey I will give it a try and include some heightened versions of spells with great differences from the original one, these spells are marked with "(H)".
