The M1 "Lancer" Rocket was the first series of rockets developed by Zenith Arms, and is widely exported to mercenary groups and armies. While outdated, the rockets are still useful in combat, and work with all M85-series rocket launchers.

As an action you can fire the rocket at a point within 300 feet. Each creature in a 15-foot-radius sphere centered on that point must make a Constitution saving throw (DC 15). A creature takes 5d8 thunder damage on a failed save, or half as much damage on a successful one.

A nonmagical object that isn't being worn or carried also takes the damage if it's in the rocket's blast radius, and all damage dealt to objects this way is doubled.
