Somehow, I understood these girls' feelings. Even though their {Fates} had manifested, I couldn't think of a worthwhile use for them. I already knew from the graveyard forums that blessings were considered an extreme luxury.
Basically, a Blessing ensured that you could defeat a corrupted undead. However, it could not guarantee your survival. The other professions that did not fight had no use for them either.
The only ones who might need them were those on the front lines. However, since most of the manifested that fought did so with {Fate} weapons, it became optional.
It was a known fact that as a Reaper progressed, their manifested {Fates} would increase in strength. The point at which they could start killing corrupted undead without blessings was at level 5 or at the mid-level of Phantoms.
