One thing that could make the current blessing/perk system more fun would be to itemize it in the form of weapon trinkets for perks and purity seals for blessings. These would graphically appear on the weapon making it more personalized to the owner. In theory, you could allow hadron to remove them from one weapon and add them to another or something along those lines in exchange for various currencies.
Basically give all weapons 4 slots for the player to equip their favored perks and blessing onto via the items and graphically represent those additions via honour badge trinkets and purity seals.
