What it does: Just walks around being pretty.
How to make it:
You don’t have the skills to make an Owl.
What it makes:
You use Owls to make Owlhead Pickles. One way is to get four of the birds together.
Or, if you don’t have the time (or the Owls) for that, you can cast two of your wingéd buddies into a Fire.
It’s not all weird pickles, though; burn an Owl in the unholy blue flame of the Ancient Mortar, and you’ll get a Potion of Following.
