Ways to increase Dragon Breath Damage?

[Starwulf]

So, I'm using a Dragonfire Adept, and I'm wondering, are there any magical items that add a +x amount of damage onto your Breath Damage, beyond A: Leveling, and B: Dragon Spirit Cincture? Got my saves for them ridiculously high(DC 50 natural, 70 if I Heighten them with my max con mod), so I'm not worried about that, I'd just like to find a way to increase it's damage.

Wow..is there really no way to increase a Dragon breaths damage besides gaining levels and Dragon spirit cinctures?

Metabreath feats (Draconomicon), Power Surge Feat (Dragon Magazine...#314, I think), your breath weapon is (Su) so some of the feats from Tome of Magic (Binder section) might help. There's some Breath Spells in Draconomicon too which may come in handy should you decide to wand them.

Think that's pretty much it though. Oh, there's some Dragon Draught's in MIC which are a one-use boost (depending on when you use it) to your BW too.
