You can get attack and def bless boxes in so many ways, honestly. Faction base, MQ, and the quest in Northwest Arch all give bless boxes that have attack and defense. Archers and EPs only have the blessings to balance them out a bit, I don't think it's necessary for all classes to have one.
Yeah I know that but it isnt usable for the whole day though
True, but they end up being what? 5-6 hours? (I don't remember the times on all of them)
Who cares. A whole day blessing will ruin the economy, silly sage wf.
