Any chance of a debuff to go with it using the red rings?
Custom demon doom runes look awesome.

Yeah sorry for the default pose, but I'd have needed 2-3 more days to make a proper animation. It's not just animating the black spectre, but adding (a lot) more bones to the chains so the hooks follow the wrists. I'll certainly edit that later, but too late for the contest.

Not sure what you have in mind for a debuff to go with it. Which red rings ?

And thanks, the custom runes are georgian's characters.

Oh, the characters.
Like 2 rings circling around the target's chest like the chains of Kel'Thuzad in WoW or Reforged ?

No just to match your model and have your completed model as the "Active" and the secondary as the lasting debuff that sits on the character like this:

Oh, sure ! I'll add a secondary model with only the characters circling. Do you think I should include the black & red fires with it, or that would be too much ?

I think the characters would be wonderful on their own, this would allow the theme to become a little more flexible.

Do they say anything in Georgian?

They say : May Satan curse you.

And I'll upload the variant of this model with only the script once the contest's poll is over.

Creative and good looking effect.
Pretty creative.
Great work!
