Bless effect when casting spells?

[Finalgenesis]

For non-sacred mages, shroud is the way to add your D bless onto them, after which all their battle damage spells has a +xxx% chance to cause affliction.

Note that overland direct damage ritual from such a mage (must have shroud) also gets the affliction bonus IIRC, so fires from afar, murdering winter, flames from the sky...etc
