The following is my first rough sketch (I wouldn't even dignify it to call it a 'draft' yet) of my rewrite of the Sorcerer class. I'm posting it here because the earlier I get feedback on where I'm heading with it, the better. I've got other ideas that aren't included below (such as the suggestions for "Hypnotism" above, I'll add them later).
"Thaumaturgy" refers to an enhancement towards craft alchemy, craft herbalism, craft weapon, etc. I don't have the details worked out yet.
"Boon" refers to a material world benefit gained from a Noble in the world trying to gain favor or something like that. "Greater Boon" refers to an extraplanar being trying to gain favor or something like that. Again, I don't have the details yet.
PP regen increases per level - the higher the level of the Sorcerer, the faster his PP regens
Channel Demon becomes a feat
Sorcerer can have three styles of magic (not including Counterspell and Summoning) - all styles are learned by 10th level
Between 1 and 10th, he's learning basic spells.
Between 7th and 14th, he's learning advanced spells
Between 12th and 20th, he's learning major spells - these are not generally combat applicable spells (basic and advanced are for that and can have more PP dumped into them in order to keep them useful throughout the rest of the character's life), these are grand ritual magics which can affect the world in major ways (such as temporarily realigning the planets in order to gain astrological benefits, powerful divinations, powerful transmogrifications (eg permanently turn a man into a demon), etc.)
