When playing Sister Mary in a high player count I often got annoyed when somebody else would pull several blesses at a time on a simple test that they would've succeeded on anyway. This prevents that once a round (note that it can activate at ANY location unlike the other covenants!), and being Mary, I also need those blesses to seal, kill, or delete, and if most of them are gone after the mythos phase and you have no bless recharge in hand, it can be infuriating. This 2 xp card might not look powerful but that's only until you see it silently doing work. If your cards consume blesses, you will love this, but if all you want out of blesses is to just make the bag easier, Sacred Covenant would probably be a waste.
