Antimatter grenade

As an action, you can either throw a grenade at a point up to 60 feet away or use a Grenade Launcher to propel the grenade to a point up to 1,000 feet away. The grenade explodes at that point, creating a particular effect in a 20-foot-radius Sphere. Each creature in the sphere makes a DC 15 Dexterity saving throw, taking 26 (6d8) necrotic damage on a failed save or half as much damage on a successful one.

Notes: Damage: Necrotic
