Holy Breath is an enemy ability used by Shinryu. It deals heavy physical Light-elemental damage to the entire party with a chance to inflict Blind. Typically, Shinryu will use Celestial Eye to make the party weak to Light before using Holy Breath.
Holy Breath I-III were abilities in the original free-to-play versions and could be used by any party member equipped with the Alexander α summon. The ability dealt magic based light-damage to all enemies. Each version of the spell dealt more damage depending on the summon's rank and had increased MP costs for each version of the spell.
In the premium versions, the Holy Breath abilities were removed and were replaced with the Banish Breath (バニシュブレス, Banishu Burseu?) abilities.
