1.1.1 Shadowbringer perk Doomsday doesn’t work with blighted

I don’t think the perk Doomsday is working as intended , when your monster heals an enemy they have a 25% chance to cast Ill fate, but I can only get the perk to trigger when a enemy is not blighted. So seeing how the whole specialization is based on enemies being blighted , it’s essentially useless as a perk
