What off-hand item do I use with a bow-equipped Demon Hunter?
When a Demon Hunter is using a crossbow, he can use a shield or even another crossbow in his off-hand at the same time. But when he equips a bow, the shield is removed, and the spot for off-hand item show a quiver for arrows.
What item can I use in my off-hand?
Solution 1:
You can use quivers, which are Demon Hunter-specific items.
Unlike in Diablo 2, you don't need bow ammo. Now the quivers are a way to provide additional character bonuses—most quivers come with a damage boost and other magic item properties.
