Flamethrower (5e Equipment)
From D&D Wiki
Martial Ranged Weapons
A device consisting of a heavy tank full of thickened fuel, worn on the back, and a flame-gun held in the hand which projects and ignites the fuel. It's useful for clearing bunkers and caves. A creature which takes damage from a flamethrower takes 1d6 fire damage at the start of each of its turns, not stacking with itself. A creature can end this damage by using its action to make a DC 15 Dexterity check to extinguish the flames. You have disadvantage on Dexterity checks with the flamethrower, due to its extreme bulk.
Special. You can make a normal single-target attack with a flamethrower, or you can spray everything in a 5-foot-wide, 75-foot long line by dispensing the flamethrower's entire payload of 10 shots. Each creature in the area must succeed on a DC 15 Dexterity saving throw or take the flamethrower's normal damage.
