Dark Souls Phantom Glow Material

Good Afternoon!

I would like to learn how to create a material such as the one Phantoms have in the Dark Souls franchise, which is a sort of emissive effect with dark shadows. (Picture attached for reference).

Thank You.

they are using fresnel multiplied by a color for the emissive.

Thank You!

My experience with materials is limited, so searching for solutions was unfruitful. Never heard of fresnel, but it was exactly what I needed.
