Molotov Cocktail (5e Equipment)
From D&D Wiki
Simple Ranged Weapons
Originally coined as "a drink to go with Molotov's bread baskets" by the troops of Finland during the Winter War, a Molotov cocktail is a form of easily-breakable bottle, most often glass, filled with a flammable substance ranging from gasoline to alcohol to even napalm-like substances mixed with a small amount of motor oil, all capped off with an alcohol- or kerosene-soaked cloth.
As an action, you can throw a Molotov cocktail at a point up to 60 feet away. Each creature within 20 feet of an exploding Molotov Cocktail must make a DC 15 Dexterity saving throw or take 1d10 fire damage and begins burning for 1d4 rounds. On a successful save, a creature takes half damage and doesn't begins burning.
After the Molotov cocktail is thrown, its flames spread to cover a 10-foot radius of the target for 1d4 rounds, lighting any flammable objects within this area aflame. Creatures that begin their turns within this area must make a DC 12 Constitution saving throw or take 1d8 fire damage.
