Combustion Cube Extract

“Thick glass, iron bands, and pray it doesn’t crack.”
A siege alchemistIt is gathered from the remains of a destroyed

combustion cube (a golem of magical jelly built to reduce everything to ashes): a few handfuls of jelly that still carry the order it was given, to destroy. It sets fire to everything it touches, and only very thick glass, which its heat cannot pass through, can hold it, and even then the glass must be locked inside an iron cage to survive the knocks of the road. A master glassblower and a smith spend days on each one, so the container is often worth more than its contents. To use it, you unlock the cage and throw the glass, which shatters into a burning puddle whose heat spreads through anything that conducts it: a suit of metal armor becomes an oven for whoever is wearing it. Water won’t put it out; it turns to steam and scalds anyone who thought they could drown it, and only magical cold can quench it. Let a crack creep through the glass at the bottom of a pack, and it’s the carrier who goes up in flames.

A sealed alchemical container token depicting a thick glass vessel filled with glowing red-orange combustible jelly, secured within iron bands and a cage-like metal frame, resting on a wooden surface beside a wax-sealed parchment label reading 'Tempten.' The container emits visible heat vapor and contains an incandescent, fire-based substance consistent with siege or combat alchemy lore. This item token is suited for use in fantasy tabletop RPG encounters involving alchemical hazards, siege warfare, or dungeon exploration, and is compatible with virtual tabletop platforms such as Foundry VTT, Roll20, and Fantasy Grounds. It functions as an inventory prop, loot token, or environmental hazard marker in D&D 5e, Pathfinder, and similar systems.
