Bards

[Townopolis]

But isn't Inspire Courage based off of your bard levels? If you only have 8 bard levels, how do you get a high enough Inspire to go with your Dragonfire Inspiration?

Hmm, I gotta look at that link later but if I do it in a gestalt game, I'd go Crusader for the Charisma synergy with both bard and warlock. Plus, Mettle is nice, and you can even Smite once a day :p

Your Warblade and Crusader levels stack with your Bard levels for determining the effect of your Inspire Courage ability.
