Im unable to access my xbox at the moment so I couldnt try this... Im just wondering if auriel's bow can still block out the sun or have the sun hallowed effect from the arrows if the enchantment bar in auriel's bow is depleted??

There's no enchantment bar, you just need either sun arrows or blood arrows and you're done.

Err yes there is.

So do i need to keep my auriel's bow enchanted to use the effect of the arrows??
