I'm looking at making a handbook for dualcasting, it's a fun build archetype and feat requirements may stop you form doing a lot of more 'standard' shenanigans while being a dualcaster, so I think it'll be fun to try and pull something useful together.
I have some notes from when I was thinking of doing this awhile back, along with a list of relevant prestige classes. I was wondering if I missed any dualcasting classes from more obscure books. What I have now:
Arcane Hierophant (RotW)
Cerebramancer (XPH)
Fochlucan Lyrist (CA)
Jade Phoenix Mage (ToB)
Mystic Theurge (DMG)
Psychic Theurge (MET)
Ruby Knight Vindicator (ToB)
Santified Mind (LoM)
True Necromancer (LM)
Ultimate Magus (CM)
Anima Mage (ToM)
Eldritch Disciple (CM) Divine 9/ Invocation 10
Eldritch Theurge (CM) Arcane 10/ Invocation 10
Noctumancer (ToM) Arcane 10/ Shadowcasting 10
Sapphire Hierarch (MoI) Divine 10/ Soulmeld 10
Soul caster (MoI) Arcane 10/ Soulmeld 10
Tenebrous Apostate (ToM) Divine 4/ Binding 4
That's it for dualcasting classes. In addition I have the following marked as noteworthy for various reasons, in the case of Blighter and geomancer simply because they are TRAPS:
Apostle of Peace (BoED)
Beholder Mage (LoM)
Blighter (CD)
Chameleon (RoD)
Demonologist (BoVD)
Divine Crusader (CD)
Sublime Chord (CA)
Ur Priest (BoVD)
Geomancer (CD)
Nar Demon binder (UE)
So I was just wondering if there is anything I may have overlooked before I get to serious writing.
