Your songs hold all the intricacies of Axis’s idealized laws, enforcing their strictures upon your enemies.
BENEFIT
You can alter any song that targets a single creature per round to become an authoritative song. When you perform an authoritative song, choose one of the following activities to prohibit: move closer to you, move away from you, make a melee weapon attack, make a ranged weapon attack, cast an offensive spell, or cast a non-offensive spell. A creature that is affected by the song and fails its saving throw against that song (if the song allows a saving throw to resist) cannot perform any action of the selected type on its next turn. This additional effect is a mind-affecting compulsion effect.
MP Increase: +2 (an authoritative song costs 2 additional MP more than the actual MP cost of the song.) In addition, the perform check DC increases by +2.
