Whirling Wards

You create three translucent shimmering shields that appear in your space and whirl around you for the duration. When you are targeted by an attack roll, you can use your reaction to interpose one of the shields. If the attack hits, the shield takes the damage instead of you. A shield can absorb damage equal to 3 times your spellcasting ability modifier. If the shield takes more damage than it can absorb, you take any overflow damage.  Once you use a shield in this way and the shield is hit by an attack, it shatters. Once you use the last shield, the spell ends.

   At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, you create one additional shield for every two slot levels above 3rd.
