Poisoner's Guide to Shadowdark


In Shadowdark there are a lot of monsters who use poisons, venoms & toxins, and in this post I’m going to break them down & add some extra details.

Poisons largely fall into two main categories in Shadowdark:

  • Natural Venoms & Toxins. These are toxic substances that monsters naturally produce & secrete; and
  • Created Toxins. These are poisons that are created by sapient monsters, and are usually applied to tips of weapons. For each of these I have added a recipe by which I believe these are created

Toxin Properties

Not all toxins are applied the same way. Some are only effective when they enter directly into the bloodstream via open wounds or are injected in by stingers, some need to be inhaled, etc. I have listed the properties of each toxin:

  • Consumed. These toxins take effect when they are swallowed
  • Inhaled. These toxins need to be inhaled to feel their effects
  • Touch. These toxins take effect when they are applied to bare skin
  • Wound. These toxins take effect by entering into open wounds, or by being injected into a victim

Erinyes Poison. This poison is made by distilling Imp Poison into a black distillate. Erinyes apply it to their arrows.

Drow Sleeping Poison. This poison is the distillate of Giant Spider Venom, which is then fortified with a concentrate of Spider Venom. The drow apply this to their weapons.

Drow Paralytic Poison. This is just Spider Venom. The drow apply this to their weapons.

Fairy Poison. This is a salve made of a very small amount of dried foxglove leaf.
