Anyone who has undertaken the task of attempting to  defeat a powerful foe,
such as a large dragon know that they have the capability to defeat the entire
party at once, or at least to cripple it in an instant. The only way to
recover from such a devestating action is to be able to heal the entire party,
with great effectiveness. This spell does just that. After having half of a
party put out of action from a dragon's breath, nothing short of a true party
heal may be able to save the party's efforts to this point from complete
failure.
