Blue Dragon Horn Shield (Patreon)

Armor (shield), legendary (requires attunement)

This shield is carved out of the horn of an adult blue dragon. While holding it, you gain resistance to lightning damage and a +2 bonus to your AC. This bonus is in addition to the shield's normal bonus to AC. While holding the shield, you can use the following properties.

Lightning Weapon. You can use a bonus action to drag a weapon you're wielding across the face of the shield to charge it with electricity. The first time you hit a target with the charged weapon in the next minute, the attack deals an extra 4d6 lightning damage to the target. Once this property of the shield has been used, it can't be used again until the next dawn or until you take 10 or more lightning damage from a single source while holding the shield.

Shield Charge. If you move at least 20 feet in a straight line toward a target and immediately make a melee weapon attack against it, you can make the attack using the shield instead. You are proficient with the attack, which uses your Strength modifier for its attack and damage rolls. On a hit, the target takes 1d6 bludgeoning damage and 1d6 lightning damage and must succeed on a DC 16 Strength saving throw or be knocked prone.

"Few creatures can harness the power of lightning, even fewer can control it. Our feeble bodies are not among them. So we must use what we can to protect ourselves from those that do."
