Time for something completely excess and unnecessary, yay! Now, in no particular order...
Super I: Dark Core
Sophia chants a spell in an ancient language before giving the foe "a glimpse of Ragnarök". The foe then gets bombarded constantly by many powerful dark spells, but that's only in a nightmare, as in reality they've been turned to stone. They can't be damaged and get out of this state after one minute.
Super II: Blessed Facade
Sophia again chants a spell in an ancient language, before setting up a magical barrier that covers her as she casts her spell on her opponent. The foe then gets smited repetitively by beams of light as they soon drain the soul out of the foe, draining HP and SP, while also leaving them poisoned.
Super III: Growing Anima
Note: This spell is an RNG spell, and can use up all her meter to cast all three spells.
Sophia, once more, chants a spell in an ancient language, as she forms the Trinity of Magic and stores it in a ritual circle which appears in front of her.
The circle then revolves before (possibly) stopping on the Thunder sign, which engulfs the foe in a cage of lightning, which then gets hit by a giant bolt of lightning, making the cage and anything inside it explode.
The circle then revolves before (possibly) stopping on the Fire sign, which bombards the target with meteors of fire and finally encases the foe in magnanimous lava where they are met with a large meteor to crash into the lava and on the foe, making the lava violently combust.
The circle then revolves before (possibly) stopping on the Wind sign, which then pushes back the foe with an intense gust of wind, before they then get entraped in a glacier, as it then shatters into enormous ice shards, which gets pushed by the strong gust of wind to plunge themselves into the foe.
Overdrive Mode: Promotion
Sophia closes her eyes, as a Heaven Seal approaches in front of her, which then shines in front of her as she gets an attire change and a direct upgrade. This changes her from a Druid to a Geomancer, and all her spells are more powerful, accurate, and they have a bigger hitbox. Even her staff is better, as it heals more and is better for melee.
Finisher: Revenge...At Last
As she is a Geomancer, she engulfs the target in light, before setting a giant orb of corrupted light upon the foe, leaving that set upon them as she then charges up for another spell. The foe sees a light shining above them, one that pierces the heavens, which is one that levitates them a small distance off the ground. Though, the image is corrupted, since in reality, the foe is being held up in the air by the ritual circle below them, engulfing them and binding them in chains. After a moment has passed, they then see their soul depart them, but the scene changes for a split second once again, turning into a dark orb of a dying ember purging itself into the foe. What they see in their eyes is a rainbow sphere with pink light revolving around it, bursting into a beautiful display of color. As if on cue however, their eyes finally revert back to reality, as another burst, this time of darkness, dissipates the foe, absorbing their soul and getting fully recovered if hurt. If the foe somehow survives, they get poisoned.
