The workflow was DAZ->AE, with notable plugins used being Saber and Particular. 

The initial image was done in DAZ, with a variety of light sources. 

• There's a rim light above and behind her,
• There's a big and very bright blue ghost light position directly behind her. I disabled HDRI lighting in this scene, so the only light sources are explicit ones. You see the effect of that on her legs, the side of the paldron and as a general rim effect
• Her eyes have an emissive material applied, causing them to glow, and light up the parts of her face, especially the eyes/nose/cheek area
• There's also a spotlight lighting up her face, roughly from the point of her left hand; this let me get more light to her face from the leftmost magic ball
• The two magic spheres are just ghost lights (purple and orange, respectively). They're invisible in DAZ, though they'll show up in AE

Once that was done rendering I took it to After Effects;

• Background is one of the shots from the game, Blasted hills, used in Act VII ending
• Stock 4K fog asset on top of that
• Then the main character
• Eyes glow from using the Saber plugin, which I use for a lot of my magic
• The magic balls are both done using Particular, another common visitor to Love of Magic's cutscenes.

Finally I made all the layers 3D, set up 3 distinct Z planes (bg, fog, character) and animated a camera in a look to get a parallax shift.

All in all about an hour's work, though most of that was tweaking and testing ideas.
