I'll try and catch one for you.
Also, if it's okay with the GM I'd like to add a few spells to Christina. I didn't add these to the CS at first because I was still playing around with them and didn't have them finished for the character in time. Essentially they're all just Unison Raids between Christina and her spirits.
Virgo and Christina Unison Raid: Spica Wave - A conjoined spell between Spirit and Wizard, utilizing Virgo's power over the earth. Virgo and her Wizard release three waves of tremors that fan out around them. Each wave is stronger than the last, the last wave crashing the earth around them into a series of deadly rock shards. Anyone caught in the radius of the first wave will feel the earth shift beneath their feet, throwing them off balance if they aren't prepared enough.
Gemini and Christina Unison Raid: Morning Star - Using Gemini to create a clone of herself, doubling her magic power, Christina brings forth the might of the celestial world with a blinding pillar of light crashing down from the sky to strike her enemies. The spell requires a lot of magic power to cast, draining both Christina and Gemini just to pull it off, but if it makes contact with her target then the results are devastating.
Scutum and Christina Unison Raid: Shield of Sobieski - Scutum and Christina combine their magic power, collectively transforming Scutum into his 3rd form: The Mask. This small, wooden mask radiates with magic power and can levitate off the ground. Upon Christina's command, the mask will circle around her and her allies, spreading its magic power over them in the form of an invisible barrier. This barrier will sustain one hit from any attack, even if it is an incredibly powerful spell. The way it does this is by converting the actual damage the person would take from the spell, and inflict it upon their Magic Power instead. So rather than taking a direct hit from a powerful spell, the person affected will simply lose magic power equal to the magic power used in the spell that attacked them.
