Arcane Shield

You create an arcane barrier with 10 Health Points. For each additional Stamina you spend, you can increase the Health of the barrier by 10. This barrier lasts until the start of your next turn or until it takes enough damage to destroy it. If it is destroyed, you take any remaining damage from the attack and gain 1 Stress. You must create the shield after you are declared as a target but before the attack is rolled.
