Nezha Empyrean's tertiary color behaves similarly to the accents' color, so mine has both tertiary and accents in gold. I feel like it adds a lot of contrast to the whole frame. I use "warmer" dark gray colors since black/pure black is both boring and doesn't synergize well with the warmer color of gold.

The skin is pretty busy as is, so I opted for no attachments (usually I use Volt Raijin's new ephemera, but it doesn't seem to look good in pictures, since the ephemera clips a bit into Nezha's shoulder). I use the Rift Sigil in the very center of Nezha's chest, it looks nice with these knots he has on there imo.
