Daggers

Daggers, as a weapon class, are usable by every class EXCEPT White Mage and Monk.  For this reason, they're among the most useful to pick up.  Their strength is surprisingly reasonable.  Many classes you'd want using Attack have unique weapons they'd rather use for damage; however, only a couple Daggers 'just' deal damage.  The majority carry a variety of on-hit effects or supportive effects that many classes can benefit from!
The Dagger damage formula is:
((Attack Power + 0-3 extra points) - Enemy Def) * Multiplier (Fast Strength)
Accuracy: 100%
Double Grip?: No
Magic Sword?: Yes
Can Throw?: Yes
