Double, double, toil and trouble;
Fire burn and cauldron bubble ...
Or whatever you use to conjure a prophecy.
Dark Ritual is high-powered Magic. It is dark purple shifting to an eerie greenish yellow. You can always count on Dark Ritual to be there if you want to cast a spell.
Note: Dark Ritual must be used over a black basecoat to see the shift effect. If used over white, it appears white.
