Spellfire Capitalization?

[Rossebay]

So, as far as Faerun's spellfire wielder goes, are there any abilities, feats, classes, or anything that expand on such a class?

Is there anything that thematically goes along very well with it?

I've got this Necropolitan Hexblade/Battledancer/Sorcerer concept going, and it (via DM) uses Spellfire keyed off of Charisma.

So, I'm wondering, what goes along well with Spellfire Wielder? I've got many things running on Charisma right now, so any ideas on things that eat spells, or recycle spell energy? :D

I'm thinking of trying to talk him into letting me put those Spellfire spell levels into Arcane Strike... And I've already figured out the Celerity+Spellfire trick for spell-invulnerability, if I so desire it.

So, any classes, feats, or abilities in general that mesh well with Spellfire Wielder, let me know.
