First off let me say that I love the darker color
HOWEVER, it's too close to the original. Sure the color is different, but for a super rare drop that I've only seen 2 people wearing, it needs something else.
Undead Antlers have those red glowing eyes and jaw...Dark Manic Mask needs something similar. Maybe make the slots on the mouth glow the same color as the Antlers? Just trying to help those out who get the drop, they deserve to stand out more.
