This is neither a guide, or an ask for help, I just want to open a debate about a class that is nearly never mentioned on the forums.
The Pathfinder Savant is a class that has always intrigued me since the first time I laid my eyes on it, being able to pick spells from other spell lists, casting scrolls with your caster level, taking ten on umd, and so much more goodies are provided from it's toolbox.
The largest problem I see with the class is that you add the spells to your class list, not you list of known spells. Atleast if you want to be a wizard, which seems to be the vanilla entry for pathfinder savant. As a wizard loses his two spells/level when he multiclasses.
A simply solution to this problem is just to pick druid/cleric instead as they get all spells on their spell list, Storm druid or theologian seems to fit the prc most if you want an archetype. The more riskier approach is to just go wizard, and hope to find the right scrolls, with a combination of finding enough spell books to "borrow".
Another problem I see is that estoric Magic can be interpreted in two ways when trying to select a spell that is already on your list, that it just do not work, or that it works, but you do not gain the +1 spell level penalty. As I read it you should be able to take a level 2 haste, as a level 2 spell if you got the wizard list. But it seems a bit strong.
Also do people think the prc is worth wasting a feat and losing a spellcasting level?, I really think it does.
