A test of many sorts, starting with the two magic fx (the circle by Sagitarius - Riteforge, from here) and the Energy Arms FX by 3dexgraphics (Renderosity). Both with some minor postwork in the final image. Plus Summoners Dantalion Creature (RH).

Embers (Boris FXOptics) and a bit of neon glow (Luminar Neo) added in postwork, finetuning and colour correction in PS.
