Barnaby's Alchemist Spark

This combustible vial can be thrown up to 30 feet (even if blocked by the target the splash effect will still cause damage) and causes 2d10 fire damage (half damage upon a dexterity save). It can also be used for its explosive force, damaging doors, cave walls, etc. 

Components: High-proof alcohol, pine resin, ground sulfur or brimstone, charcoal dust, bees wax, quicklime.

• • Yield: 1 Standard Throwing Flask (approx. 4 oz)

  • Prep Time: 1 hour (plus overnight resin curing)

  • Shelf Life: Highly stable if kept completely dry; absolute fire hazard if stored near open flames.

  Ingredients

  • 2 oz High-Proof Moonshine / Grain Alcohol (The volatile liquid fuel base)

  • 1 oz Sticky Pine Resin / Pitch (The clinging agent to ensure the fire sticks to armor and targets)

  • 1 tbsp Finely Ground Sulfur / Brimstone (To lower the flashpoint and add a choking, noxious smoke)

  • 1 tsp Hearth Charcoal Dust (The carbon accelerator for rapid thermal expansion)

  • 1 tsp Dry Quicklime (Calcium Oxide) (The exothermic catalyst sealed in a wax paper packet at the neck of the flask)

  Instructions

  1. Melting the Pitch: In a small, dedicated iron skillet over a low, controlled ember, gently warm the pine resin / pitch until it liquefies into a thick, amber syrup.

  2. Blending the Fuel: Slowly pour in the high-proof moonshine, stirring constantly with a wooden rod to dissolve the resin completely into the alcohol without letting it flash or ignite.

  3. The Chemical Dint: Remove the skillet from the heat. While the mixture is still warm, whisk in the finely ground sulfur and hearth charcoal dust. The liquid will turn a murky, dark brown-black with a heavy sulfurous odor.

  4. Bottling the Base: Carefully funnel the viscous mixture into a thick-walled glass throwing flask, leaving about an inch of empty space at the top. Allow it to cool until the resin firms up slightly, creating a sticky, clinging suspension. Cap this with a layer of bees wax.

  5. The Quicklime Seal: Just before corking, drop a tightly wrapped and waxed paper packet of dry quicklime into the neck of the flask, ensuring it hangs just above the liquid level, completely isolated from any moisture. Your bees wax divider must be firm and in place or "Boom"!

  6. Sealing: Cork the flask tightly and dip the entire top in melted beeswax to seal out cellar dampness.

  Barnaby's Note: "When you hurl this one, the glass shatters, the moonshine-and-pitch slurry splashes across the target, and the quicklime drops straight into the mix. The moment it hits sweat, damp air, or a drop of liquid, it flash-heats and sets the whole mess off. Perfect for clearing out stubborn pests—two-legged or otherwise."
