You channel divine power into a shield you are wielding and throw it at a target you can see within range. The shield then bounces from that target to up to three other targets of your choice within 10 feet of the first target. Make a melee spell attack against each target, including the first. On a hit, a target takes 2d8 radiant damage. After the shield bounces off the last target, it returns to your open hand. A target can be a creature or an object and can be targeted by the shield only once.
After casting this spell, you lose your shield bonus to your AC until the start of your next turn.
At higher levels: When you cast this spell using a spell slot of 4th level or higher, the shield can bounce to one additional target for each slot level above 3rd. When you cast this spell using a spell slot of 5th level or higher, the subsequent targets must be within 20 feet of the first target. When you cast this spell using a spell slot of 7th level or higher, the subsequent targets must be within 30 feet of the first target.
