World of Shadows! Plunge your worlds into an eternal darkness!
works best from 0.6 to 1.2 for a more chaotic look!
it's not trained with other colors HOWEVER you can get them at a push (red and black:1.5) you just need to increase the weight and remove purple and black
try combining with Navimixu's world morphs! or konyconi's AI's or if you feel more WILD try out DonMischo's Billions of wildcards!
try adding dark magic if you want to get a magical vibe!
