Well, heres what's gonna happen; you could have the same "based spells" as another character. For example, >blank< could have the same type of spells as Sapphire (of which are water based spells.) ^^ First I'll make the roleplay as a conversation.
Don't worry, @Dr. Alphys ! ^^ I don't know when the roleplay will be created, so that gives you time to choose a name (The name could be any name ^^ and the characters would be allowed to use spells. And it will be an open Roleplay so anyone could join. [well, maybe an open roleplay, I'm not too sure at the moment o-o )
