Undestined Stormcaster
The death scream of a creature killed by lightning.
Weapon (any bow, crossbow, or non-fusil firearm).
Reverse engineered by winged arcanosmith Terri Pemberton, this arctech armament allows a shootist to rain forth wind, thunder, and lightning. Similar to an arcane fusil and filled with shining fulgurites (air-aspected planarite), it uses electromagnetic engineering and a series of coils to generate a powerful ceraunic current.
Whenever you would deal damage with this magic weapon, you must instead deal your choice of lightning or thunder damage. When you hit a creature with this weapon, you can push it up 5 feet away from you in a straight line.
As an action, you can use this weapon to cast lightning bolt (save DC 15) without components. Once the weapon has launched such a bolt, it cannot do so again until the next dawn.
