Create a Blue Mage Spell!

[Bonbori]

I'd love to eventually be able to use some of Tsukuyomi's abilities. Nightfall would probably lend itself best to being converted into a playable spell.

Lead of the Underworld: Randomly targets a nearby enemy and unleashes a powerful line attack, dealing unaspected damage with 1000 potency split between all affected enemies.

Steel of the Underworld: Randomly targets up to 3 nearby enemies and unleashes a powerful cone attack at each of them in quick succession, dealing unaspected damage with 100 potency and inflicting a stack of Nightfallen (up to a maximum of 2). Each stack of Nightfallen increases the damage suffered from subsequent Steel of the Underworld strikes by 100%.
