EyeontheMountain said:Past thsoe two, none really, though next I would say complete adventurer, as it has seomthing for everyone. Then the rest of the complete books (sans psionics) Then races, environment nad down the road.
Flexor the Mighty! said:Not just WOTC either, and Dm orientated since I'm not doing all the splats right off the bat at least. Advice books are probably less vital than books with must have mechanics or monsters.
DJCupboard said:I would vote Expanded Psionics followed by complete Adventurer (definitely the best of the four) followed by either GR's Advanced Bestiary or WotC's DMGII.
Gargoyle said:PHB II or Spell Compendium. The former for various class options, the latter if you just want lots of spells without having to flip through a bunch of books. Or Draconomicon for dragon goodness.
