Festerwood Buckler

Armor - uncommon

This festerwood shield is riddled with amber pustules that glow with a low, yellow light. While holding this magic shield, the pustules emit bright light in a 5-foot radius and dim light for another 5 feet. In addition, while you’re holding the shield, you can use your reaction when a creature that you can see within 5 feet of you misses you with an attack to bash that creature with the shield. When you do, that creature must succeed on a DC 13 Dexterity saving throw or take 1d4 + 1 acid damage.

The wood was as dark as it was dangerous. It was both the problem and the solution. For me, it was as much my best defense as it was my stalwart weapon.
