1. feathers of liberation
Feathers of liberation are used to free a captive monster with the
'liberate' command, and can also be crafted into a quill. They can turn up
in several ways:
Every foraging attempt has a small chance to turn up a feather. The odds
rise if you have learned the feather sense skill, and rise further still if
you have a hero pacifist character in your account.
A birdhouse occasionally produces a feather alongside a freshly laid egg.
Releasing a chick that has hatched in a nesting box always leaves you with a
feather.
Collecting eggs from your own chicken at your player home has a chance to
also yield a feather, provided the chicken's mood is high enough.
Completing a daily challenge can randomly reward a bundle of feathers.
