Zeniths

Zeniths are a state of mastery of a Birthclass, unlocking both a more powerful (and differently-named) version of a Tune user's Motif (known as a Zenith Motif as opposed to an Innate Motif) as well as improvements to their actual Tune making it a perfect melody and therefore unlocking Zenith Abilities too. Both a Motif and a Crescendo is required to attain Zenith State. Zenith State is unlocked with a Zenith Intensifier.
