Damage Shield

You gain the ability to protect your allies. When you choose this feat, you gain the following benefits:

• Increase your Intelligence, Wisdom or Charisma score by 1 to a maximum of 20.

Whenever you make an attack that either deals damage, needs a saving throw, or effects creatures other than yourself; you can create a shield around a number of creatures equal to or less than your Proficiency Bonus as a Bonus Action. While this shield is active, the creatures you choose gain the following effects.

• They do not take damage of AOE, Line and Cone attacks that you make. (For example, if you cast Fireball; they automatically succeed on the Dexterity Saving Throw and they take no damage where they would've taken half on a success. Or if you cast Shapechange and transform into an Adult Green Dragon and use its breath, they succeed on the Constitution Saving Throw and take no damage where they would've taken half on a success.)
