Vassilis's Perfect Defense

At the start of each of your turns, you create three arcane barrier that intercept attacks requiring attack rolls or the Magic Missile spell targeting creatures within 60 feet. Each barrier reduces damage taken from a single attack or one Magic Missile spell by 5. You can apply all barriers to one attack or Magic Missile spell or distribute them across multiple attacks or Magic Missile spells. Unused barriers expire at the start of your next turn.

At Higher Levels: When you cast this spell using a spell slot of 4th level or higher, you create one additional barrier at the start of each turn for each slot level above 3rd.
