I'm planning to recreate one of the fairy tales (Sleeping Beauty) through the ways of Pathfinder, and now I'm stucked with my main antihero, who is actually a witch (modeled after Maleficent). Well, my main concept is to create a witch with strong ties to the First World, but I couldn't find an appropriate patron for her, so now I'm thinking about multiclassing with the sorcerer class (fey bloodline). My goal is to create a lvl 20+ character, who can cast Maleficent's iconic spells (for example: dragon form III/shapechange, eternal slumber, wall of thorns), while has a unique feature found just in my campaign (i imagined two main ways: a shadow weaver sorceress-witch similar to the Fellnight Queen, or a cold Irriseni Feycaller which role I find really interesting). The place and remaining aspects of the story depends on this choice.
I'm a newcomer in the terms of playing, but consider myself a great fan and used to create stories based on Pathfinder, I know, I'm kinda dreamer. :) Anyway, could you give me some advice how to fabricate her to be the most effective and mythical she can be?
Thank you. :)
