3 to 1 unique recipe doesn't work for foulborn uniques

The recipe does work for other influenced boss uniques like Blasphemer's Grasp, so it should work for foulborn uniques. Being foulborn doesn't act like being corrupted either, so it should not be a criterium to disable the recipe. Of course, the foulborn modifiers should act like unique variants, meaning the same foulborn modifiers need to exist on all 3 items for the recipe to work.
