Ok, the result is that I am going to add a couple of new spells to each School of Magic, making sure that they all have the same number.
I am ALSO going to be adding Casting Options to as many spells as possible as well.
Casting Options are ONLY going to be available to Adepts (thus a Fighter or Rogue who learns spells will NOT be allowed to use the Casting Options). I feel that this allows the Adepts to be special when it comes to spells, while still allowing non-Adepts the ability to learn some spells...
