This simple looking oval shield seems to be made of bronze and ebony with the symbol of Ilmater etched into it's face.

When you are targeted by an enemy’s spell, you can use your reaction to have the shield swallow part of the spell. The shield gains a number of charges equal to the spell level
of the triggering spell. You are still subject to whatever effects the spell would normally inflict on you.

When you hit with an attack, you can choose to expend any number of charges from the shield, dealing an additional 1d8 radiant damage per charge expended, which
is inflicted on the target of that attack. If your attack strikes multiple targets, you must choose one target from the group to be subject to this damage.

This shield has 4 charges, and regains 1d4 expended charges daily at dawn.

Shields require the Utilize action to Don or Doff. You gain the Armor Class benefit of a Shield only if you have training with it.
