I was able to squeeze some spellblades in by dropping teleport off my drake helm. Have immunity to MDJ, Greater Dispelling Screen, Chain Dispel and Reaving Dispel. Remembered I don't have to worry about Greater Dispel Magic because it's a level 6 spell and I'm immune via Mystic Shield.
I'm not sure if there really is a way to get immunity to slashing dispel and spelltheft, is there?
Choose Destiny does look pretty insane...I'd like to try to figure out a way to pick it up without dropping GVotD though. I like my nice, round, charisma score. Makes things easy.
If there were a magic item that granted the feat Endurance I should be able to, but I haven't found anything like that (and I've looked). Then I could adjust my ability scores and skills to fit in Arcane Disciple via Psychic Reformation.
