[Wish]

In Dom3 a "strong bless" is reserved for when a player suffers from a "strong sneeze"

actually when you are selecting magic for your pretender you might notice things popping up at the bottom of the magic window like 10% regeneration (in the event of a 6 nature pretender)

these are the extra effects, besides a morale boost, that your bless will give sacred units.

playing with increasing other paths above 4 or 9 will show you the other effects, even without a manual.
