Argentum Fidei

The Argentum Fidei is a weapon in Act One. It is the starting weapon of Emily.

The sword's damage increases based on the user's level of Faith. As it grows stronger, the "plus number" next to the weapon's name increases. At max faith in Act One, it is called the Argentum Fidei +6, though it is possible to miss the optional event with Skip and wind up with the sword at +5 instead.
