1. Quiver of Lightning Arrows - I am using it with a +1 longbow. It gives bonus damage but description also says it has speed shock ammo but speed part is not working as it is not giving extra attack. Additional bug is that when you hit with it, it uses up two charges but when you miss it uses up 1 charge. It should be one charge no matter if you hit or not.

2. Quiver of Ultrasound Arrows - It does give bonus damage and even extra attack but like above it uses up 2 charges when you hit your target but only one charge when you miss. It should be one charge no matter if you hit or not.
