Salvo

You launch three projectiles at points you can see within range. Each creature within a 10-foot radius sphere of each point must make a Dexterity saving throw. A creature takes 3d6 fire and 3d6 kinetic damage on a failed save, or half as much damage on a successful one. A creature in the area of more than one sphere is affected only once.

The power damages objects in the area and ignites flammable objects that aren't being worn or carried.

Overcharge Tech. When you cast this power using a tech slot of 6th level or higher, you create four projectiles. When you cast this power using a tech slot of 8th level or higher, you create five projectiles.
