I couldn't miss the chance to practice my drawing!
Mage's Ballad and Mage's Ballad II, and Mage's Balled III are songs for the Bard. They each have a Refresh effect, which causes the character to recover a small amount of MP over time. Mages Ballad is learned at level 25, Mages Ballad II at level 55, and Mage's Ballad III at level 85.
Mage's Ballad is a Level 30 Bard spell. Both Mage's Ballad and the Bard Soul Crystal are obtained after completing the quest "A Song of Bards and Bowmen". Mage's Ballad deals unaspected damage to a target with a potency of 100. It increases the critical hit rate of all nearby party members by 2% for 30 seconds.
Mage's Ballad activates the Song Gauge, where it displays the time remaining for its duration. Every time critical damage is dealt by Caustic Bite or Stormbite, the trigger effect Repertoire activates, resetting the recast times of Bloodletter and Rain of Death, allowing Bard to bypass the long cooldown of the skills.
A ballade is "a poem normally composed of three stanzas and an envoi. The last line of the opening stanza is used as a refrain, and the same rhymes, strictly limited in number, recur throughout."
