Armor (shield), uncommon (requires attunement) 

This finely crafted shield carries the blessing of Perun the Thunderer. Flickers of electricity occasionally jolt over the titanium-inlaid symbol in the middle. 

While holding this shield, you can use an action to awaken its thunderous essence and create minor magical sensory effects originating from a point you can see within 60 feet of you. The effects are harmless but reminiscent of a thunderstorm, such as a gust of wind, a peal of thunder, or a flash of lightning. 

In addition, if you are targeted with a melee attack while holding this shield, you can use your reaction to cast the thunderwave spell (save DC 13) from the shield. If the attacker fails its saving throw, the attack misses. Once you use this property, you can’t use it again until you finish a long rest.
