The World of Sin
I do classes just like in the books only one thing is different for the prestige class requirements. I do not require you to be a certain race in order to play a class. For instance the Arcane Archer spell class requires you to be either an Elf or a Half-Elf. I do not require you to play an Elf to get this class, but most NPC’s of this class are Elf or Half-Elf. Just like most NPC’s of Stalwart Defenders are Dwarves.
Aside from this just note that all classes from Pathfinder and 3.5 are allowed in my game, but Psyonic classes. They can alter the entire game that I have made and it really takes away from the experience to have a character like that in games.
There is one other note for classes, and that is that I allow the Blood Magus from either 3.5 or the Blood Magus that I made; see Blood Magus Class. If you do play my version of the Blood Magus kindly note that the class is subject to change as the game goes on since it hasn’t been tested and I’m not sure if it is underpowered or overpowered. I made it simply because there wasn’t very many good prestige classes for Sorcerers and Wizards.
