Ok, some more specifics on the contents of the Wizards, Bards, and Sorcerers book. Here are some of the things you'll read about:
1) Wizard Traditions: Calastian Battle Mages, Society of Immortals, Necromancers of Hollowfaust etc.
Each group has a brief description, current leadership, base of operations, how to become a member, arcane motifs (you can customize how your spells look), favored feats, favored skills, favored spells.
2) Libraries and Academies: Volumes of Lore (including a random table of 100 sample books complete with cool names like 'Unraveling Albadian Ice Magic'), Spellbook Dweomers and Traps, a varient rule on Spellbook Alternatives like spellstaves, tattooing, and runes.
3) Bardic traditions: Blades of the North, Brotherhood of the Lamp, Chorus of the Banshee etc.
4) Philosophies on bardic magic: including varient rules on how noise levels affect magic, composition and performance, bardic enchantment.
5) Epics of the Scarred Lands: I loved this section because it describes sample epics and songs common to the land. Take these, make modifications, and use them as treasures to be found in your world. Example: 'Of Mithral and Blood' is an epic poem that your bard can recite while casting some common spells (it provides a list of good spells to use with each epic).
6) Sorcerous traditions: the sorcerors of the Scarred Lands seem to be tied to the Titans (those who fought the Gods in the world's history) so this section describes the different 'cultures' of sorcerors. The Bloodtrail, Cult of the Eighth Eye, The Preservers of Life etc.
7) The basics of sorcery: How does it manifest in players--some ideas on how to play them etc.
8) The Ways of Lore: 60 pages of new feats, prestige classes, spells and equipment. Some nice feats include 'Pied Piper,' 'Arcane Trinity' Elemental Focus, and Ghost Spell
prestige classes which caught my attention are: Adept of Flame, Demonologist, and Master Cabalist ("wizards who seek to exploit the pacts and laws that bind gods and their servents to the Scarred Lands")
Like I said in my earlier post, once you read these books, you'll look at the PHB's 'wizard' or 'fireball' and think how boring these sound in comparison to the colorful setting Sword and Sorcery has conjured up with these works.
Gee... what sounds more interesting, casting 'Children of the Serpent Mother' or 'Grease' hmmm...
