I'm not up to MoTB yet sorry but I got a decent bard for the OC. A little weak melee but I still notice some damage being done especially considering I have all the curse songs... I plan on tweaking a little perhaps and trying again.

For MoTB first I have to figure out how I tweak the basic build but if I went with this one I would go RDD2F1Bard7 as epic levels and take: chorus of heroism, Great Strength 1 and 2 (1 a fighter bonus), Song of Requiem, Hymnn of Requiem, Epic Divine Might, Epic Spell: Plague of Fowl? or Summon Devil
