Blood Magic

You have learned how to use your body to enhance your magic, granting you the following benefits:

• Your Constitution score increases by 1, to a maximum of 20.
• You can choose to expend one Hit Die whenever you cast a spell. Roll the die, and add the result to one roll of the spell. That roll must restore hit points or deal damage. You do not regain hit points when you expend a Hit Die in this way.
