If you have chivalry it is better to use consecrate weapon rather than chaos damage. Chaos damage means it randomly targets a damage type like fire, cold, energy, etc. The quiver takes precedence over damage types, but not certain how it works with consecrate for the quiver of elements. I suspect it puts each elemental damage into the lowest so negating the damage spread.
I don’t wear any quiver anymore. I like the quiver of infinity for holding arrows because it is blessed. You have to wear the quiver infinity to get the lower ammo cost.
I wear the spell focusing sash and the Ranger’s Cloak of Augmentation, which are better than a quiver. The spell focusing works with spell on the weapon too, but not certain that’s an improvement or detriment.
