This is hardly original, but I keep looking at it. I'm going to spend the afternoon optimising her.
Bard 6
Lyric Thaumaturge 3
Virtuoso 1
Sublime Chord 2
Virtuoso +8
Metamagic Song, Practiced Spellcaster and Practical Metamagic
Metamagic Feats, probably as many as I can fit from; Extend, Persist, Sculpt, Disguise, Empower, Maximise, Reach, Fortify, Entangle
and probably at least one each from Arcane Thesis and Metamagic School Focus
I don't want to include anything from Dragon Magazine, though Easy Metamagic is obviously awesome, and Sculpt Spell would benefit hugely from Ray Coning.
I'm feat starved, so I'll probably want full flaws, again without Dragon Magazine. 2 Unearthed Arcana Flaws normally means something turns out painfully lacking, but so be it.
There seem to be 4 races that give a bonus to charisma without level adjustment
Hellbred
Lesser Aasimar
Spellscale
Star Elf
I'm trying to picture a Hellbred Bard, driven to giving inspirational performances of improvised and mournfully beautiful hymns about appreciating life because happiness can be short lived. Maybe another time.
Elves and Aasimars have sort of the same problem.
So she'll probably end up being a Spellscale. A confident and beautiful dragon scaled human born comedienne who's spent her life being shoved and heckled and accused of being half kobold.
Okay, that's a good start, time to start running the numbers on paper.
