Does it have unlimited charge? I shot it using sunhollowed arrows and right when the power meter was about to empty, a tiny sliver remained on the meter, and the arrows exploding still occured, although this could have been because of the arrows. Does anyone know if it has unlimited charge?

And is there a helm somewhere that goes with the ancient falmer armor you get from the arch-curate? I'm currently using a circlet.

No one knows?

No helm I'm afraid, not sure about Auriels Bow.

The bow doesn't have unlimited charge, and the arrows still explode because they themselves have a enchant.

Wow that svcks... mine can only shoot like 10 times before it runs out
