Infernal Release

You have mastered the magic that binds you,
allowing you to take your true demonic form.
While in this form, your size increases to large,
you have a flying speed of 60 feet, and 1D4 souls within your lanterns temporarily manifest. If a creature hits you, you may sacrifice a manifested
soul. If you do, you gain HP, instead of losing it,
equal to the damage dealt. You return to your original form after all souls have been sacrificed
or when you choose to do so.
