Overshield

Armor - uncommon - requires attunement

While holding this large shield, you gain a +1 bonus to your AC. This bonus is in addition to the shield’s normal bonus to AC. The bonus becomes +2 while you have at least 1 temporary hit point. While you have temporary hit points, the shield emits a slight blue glow.

In addition, you can channel the heroic resolve within the shield as an action to gain 1d6 + 8 temporary hit points. Once this property of the shield has been used, it can’t be used again until the next dawn.

Where the sword struck him, there were no marks. His shield seemed to dance on his arm. In that moment, his blue-lit face betrayed a bored patience. I wasn't going to harm him, and this fight was meaningless from the start.
