Thunderarrow

Ammunition and weapon (javelin), rare
Component: Elemental (storm) volatile mote of air

The breakthrough that ended the Iron Incursion, these 4-foot-long steel javelins are enchanted to explode upon impact. They can be used as ammunition for a raikyu or thrown like normal javelins by a creature with a Strength score of 15 or higher.

On a hit, a thunderarrow explodes, dealing 8d6 thunder damage to the target. Each other creature within 30 feet of the exploding thunderarrow must make a DC 15 Constitution saving throw, taking 8d6 thunder damage on failed save, or half as much damage on a successful one. A creature made of inorganic material such as stone, crystal, or metal takes twice as much thunder damage from this effect.

Raikyu

A raikyu is a martial ranged weapon. It weighs 72 lbs; is a little over 5 feet wide; uses javelins as ammunition; has the Ammunition (range 400/1600), Loading, Superheavy, and Two-Handed properties; and deals 3d10 piercing damage on a hit.

• Superheavy. A Huge or larger creature can move with and make ranged attack rolls with a Superheavy weapon without penalty. A Large or smaller creature can’t make ranged attack rolls with a Superheavy weapon unless it is set up. A creature with a Strength score of 15 or higher can use an action to set up a Superheavy ranged weapon or take one down. If a set up Superheavy ranged weapon is moved, a creature must use an action to set it up again before it can be fired. Every foot a Large or smaller creature moves while carrying a set up Superheavy weapon costs 1 extra foot of movement.
