I'm very confused because I really have no idea have to use Battle Chant's effect with the Battle Cry flexible attack rules.
The power effect is:
Special: When you use battle chant, you can choose any battle cry effect you know as if you were making a basic melee attack, with the battle chant attack roll taking the place of the basic melee attack roll.
My question is, with this at-will ranged spell's special effect, can a bard use the battle cries every time he wants as melee attacks without worrying about the flexible attack rules?
