The Generic Classes: (almost everything)
When choosing a class you may choose which saves are good and which are poor. The # of good/poor saves is stated by the class. You may also choose your class skills. All classes get bonus feats, you may choose some class features of the standard classes as bonus feats.
Expert: d6; medium base attack; two good saves, one poor save; class skills: any twelve plus Craft and Profession; skill points: 6+Int mod; All simple weapons, one martial weapon, light armor; bonus feats:Lvl 1,2,4,8,12,16,20
Spellcaster: d4; poor base attack; one good save, two poor saves; class skills: any four plus Craft, Knowledge (all), and Profession; skill points: 2+Int mod; One simple weapon, no armor; bonus feats:Lvl 1,5,10,15,20; spellcasting as Sorcerer, fewer spells per day, select spells from cleric, druid, and sor/wiz lists; choose if you are arcane or divine spellcaster - arcane uses Int or Cha, divine uses Wis; you may multiclass between arcane spellcaster and divine spellcaster
Warrior: d10, good base attack; one good save, two poor saves; class skills: any six plus Craft; skill points: 2+Int mod; All simple and martial weapons, light and medium armor, shields (not tower shield); bonus feats:Lvl 1,2,4,6,8,10,12,14,16,18,20
The DM probably shouldn't apply multiclassing penalties.
From the UA preview thread. Triilobite, could you post the feats from the book granting class abilities. Thanks.
