When sprinting you slowly begin to spread out your feathers which grants you a small boost in speed and the slow fall effect, when you stop sprinting or you're in the air your slowfall slowly withers away.

While you have built up feathers you are able to dash with [Primary] with a very little cooldown.

You are unable to eat meat and fish, you are limited to a vegetarian diet.

You heal faster when under the slowfall effect, otherwise you heal slightly slower.

You're unable to wear an Elytra as you already have wings.
