What's up with the player's face? Shadowscale armor is updated or it's just player's skin is pitch black. And what about eyes?
That is the effect of Yoraiz0r's Spell. It's a vanity effect from Yoraiz0r's Dev Armor which makes it that your character has the glowing eyes. In this case, it's the Shadowscale Armor with the Spell as a vanity item part of the armor giving that effect.
