The Sentinel's Shield

Shield Throw

As an action, you throw The Sentinel's Shield at a creature within 60 feet and deal 3d8 + Strength modifier. If you roll the same number on two or more of the d8s, the shield ricochets toward another creature of your choice within 30 feet of the previous target. 

If you roll the same number on the next target, make an attack roll against the new target and make a new damage roll. The shield can hit up to 4 targets.

Perfect Ricochet

If any attack made during the ricochet is a natural 20, the next ricochet attack is made with advantage and deals an additional 3d8 bludgeoning damage.
