Bows are unique Weapons in that their attack power is not solely determined by attack. Instead, the formula is (HIT/2)+(ATK/2).
Their skills are primarily multi-panel skills hitting multiple targets. The weapon's main quirk is that despite low damage potential, it can inflict a number of status ailments upon the enemy with it's Special Attacks, so a Bow-user will benefit from having Specialists that add Ailments to their attacks on their weapons.
The best bow users are Majins and Archers. In practise, you will probably only have the Archer use a bow regularly, although it is a good idea to have your first Cleric reach level 3 with one, in order to unlock the Archer class. This also makes it slightly easier to get your first few kills with a Cleric - enough to get him or her a mage/skull pupil, at least, after which they'll be able to learn their pupil's spells.
