Holy Song is an important story-related light or wind elemental spell that involves spreading a holy and invigorating light across the full battle field to temporarily boost all party members' offence and defence. Due to the status of this spell, this cannot be considered as a typical attack, and thus it cannot be categorized under the typical novice/intermediate/advanced tier system that is used for most games.
