Stratics can help there. Search for blessed, find the receipe on the list, click on that and you will have a list of what spoils and what drops it. Click on the mob and it will tell you where they are.
The only one that I know of for sure is the Nephilim Preatorian. They are in DN, Martyr's, Witches and one other I think. Might be Saints, prolly is cause it's like a lvl 70-71 mob. I only know this cause that's where my clan got the recipe for our crafters.
