[fuzz]

Which one is good for the Bow and Dual Daggers? What is their difference?

[Shichiya]

Bow>Safe distance+high output
DB>high mobility+attack speed(if done right)

It explains it in their description, marathon runner reduces continuous stamina drain such as when you have demon mode activated with DBs, or when you're charging the bow, and Constitution reduces fixed stamina usage like when you dodge. For DBs Marathon runner is clearly a lot better, while for Bows you're better off with Constitution. Also, Dash juice is important for both of these weapons.
