When you assume the form of a creature though the effects of Polymorph, Shapechange, the Wild Shape ability, or any similar effects, you gain +2 AC and your weapon attacks count as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage. These effects end when you revert to your original form, or when you choose to release them.

Whilst assuming the form of a creature though the effects of Polymorph, Shapechange, the Wild Shape ability, or any similar effects, you may choose to apply one of the following Aspects. The Aspect ends when you revert to your original form, or when you assume the form of a different aspect.

Curse of the Brazen
When you are in the form of an Aspect, and you would take damage that reverts you to your original form, instead of having any excess damage carry over, you instead take the full damage again to your original form.
