Create a Blue Mage Spell!

[Auryan]

More spells! Time to get a little naughty.

Auto-Ribbon - Self-use only. Renders the blue mage immune to most status ailments (excluding Death and boss specific status effects).
Note: This ability is not a usable spell, but rather a support ability that will always be active if the BLU has it equipped. Downside is that support abilities will take 3 slots instead of the usual 1 that the other spells take.

People are so going to troll with this next one, but I like the idea of friendly fire spells. Maybe it'll be just too toxic, but here goes.

Mega-Graviton - Shadow-aspected spell that affects friends and foes alike. Reduces targets HP to 60% of max HP and place several status ailments on all targets within the radius. Status effects include: Slow, Sleep, Silence, Blind and Doom.

Cast time: 3 seconds
Mana cost: 60% of the caster's maximum MP

I want to make this one a really nasty, canon-like spell with some drawbacks and theory crafting around it.

Copycat's Grudge - Shadow-aspected spell that deals damage to a target based on the amount of blue spells learned and equipped. Will deal more damage with more spells learned and more damage with LESS spells/abilities equipped. For example: the spell will deal 100% more damage if the blue mage has only 12 spells equipped. Percentage is subject to change.
