EAT-17 Expendable Anti-Tank Rocket Launcher

A bright streak flashes from your shoulder mounted launcher to a point you choose within range and then burst into an explosion of flame and shrapnel. Each creature in a 10-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 8d6 fire damage on a failed save, or half as much damage on a successful one.

The fire spreads around corners.
