Beguilers do have some decent buffs, and would have a pretty easy time getting into that particular prestige class...  Though, now that I think about it, if it's buffs and healing you're after, a Beguiler going into a refluffed evil version of the Rainbow Servant (http://dnd.arkalseif.info/classes/rainbow-servant/index.html) prestige class would be quite solid.  Say, the Evil, Fire and Law domains, to reflect Baatezu-worship instead of willing service to Couatls?<br/><br/>It'll be up to Zaer to weigh in on whether to go with the text (full casting progression) or the table (loses four levels of casting progression).  The former is what people generally say to go with (text trumps table as a general rule), but even with the latter, it would be a full-list spontaneous caster adding all Cleric spells to their list of spells known, which is definitely pretty powerful for buffing and healing.<br/><br/>Maybe have the Warmage, Beguiler and Dread Necromancer go with the table, while all other arcane spellcasting classes get to use the text...<br/><br/>I was thinking a Shadovig (http://www.realmshelps.net/monsters/block/Shadovig) might make for a fitting base race, with Versatile Spellcaster (http://www.realmshelps.net/charbuild/feat/Versatile_Spellcaster) used for early entry into Rainbow Servant.<br/><br/>And I'll see what I can find for traditional warrior-types for you.  A Psychic Warrior with the right templates could admittedly work pretty well...
