Seriously, Elemental Savant for a Sorc PrC? By the book, you can't even get into that until 13 due to cross class skills. Talk about being pigeonholed into nuking.
What about all the other prcs?
Wild Mage (Complete Arcane)
Shadow Adept (Faerun)
Dreamer (Ultimate PrC vol.1)
Mind Bender (Complete Arcane)
Arcane Delver (Ultimate PrC vol.1)
Wayfarer Guide (Complete Arcane)
Nightmare Spinner (Complete Mage)
Prenumbral Lord (Ultimate PrC vol.1)
Arcane Avatar (Ultimate PrC vol.1)
Fatespinner (Complete Arcane)
Pale Master (Complete Arcane)
Arcane Devotee (Faerun)
Keeper of Songs (Ultimate PrC vol.1)
Seriously...these are just a few off the top of my head.
Elemental Savant? Really?
