A shimmering barrier of force appears around a willing creature's body that protects them from attack. The barrier has 6d8+10 hit points. Any damage that the creature takes instead damages the barrier. When the barrier is reduced to 0 hit points, it explodes. All creatures of your choice within 20 feet of the creature you protected with this spell must make a dexterity saving throw. On a failed save, they take 3d12 force damage or half as much on a successful save. The barrier does not explode if you end this spell early.
