Kuko Shakaku

Kuko Shakaku is a pretty decent bow for Amazons, but also Sorceresses and Paladins.

The "Fires Explosive Arrows" only works for normal attacks and not skills; it does, however, use the Explosive Arrow skill without paying for the mana cost (although at a lower, fixed skill level). The

Exploding Arrow pairs well with the Sorceress' skill

Enchant or Paladin's

Holy Fire: fire damage boost is carried by the explosion.

For the Amazon, the +3 to Bow and Crossbow skills combined with the +3 to

Immolation Arrow should carry you far enough into nightmare.

The built in

Pierce is pretty good too. A viable bow until you get into the higher level ones like

Demon Machine or the Runeword Brand.
