Celestial Shape

You learn to twist your Wild Shape into certain forms of celestial creatures in addition to beasts. You gain expertise in Nature and Insight. Following the other rules of Wild Shape or the Circle of the Moon, you can expend two uses of Wild Shape at the same time to transform into a celestial which you have seen.

Manifesting and maintaining a celestial shape is far more difficult on the body than taking other shapes. Upon returning to your normal form you gain a level of exhaustion for each time you used Wild Shape to take or maintain a celestial form.

Examples of celestial creatures include but are not limited to the Unicorn and Pegasus.
