Bard
Bard is a Sprite, Phantasm hero. This means he can command Sprite, Sylph or Siren stacks and grant them an efficiency bonus. He also has a ranged Psychic attack, which is fairly good and the hero isn't expensive to maintain.
The fact that he is a Sprite isn't very good, since Sprites/Sylphs/Sirens have a very bad habit of being stackwiped because of their weakness, which can result in your Bard being destroyed. I recommend that if you get a Bard to avoid using those units or stack them in sufficient numbers they won't all be killed.
Bard's main ability is Song, which is almost exactly the same as Valor except the starting bonus is +2% instead of +3% BUT, it also subtracts from the Primary and Counter AP of the enemy the same amount that is added to you. It is therefore an excellent offensive and defensive hero.
Moreover, I do believe that Song stacks with Valor, so you can have multiple "Valor" heroes.
The lvl 14 Charisma is not of much value.
