Some monsters spit venom at you, which acts a projectile attack. This takes the form of either
- blinding venom, which blinds you as a cream pie when you are hit by it, or
- acid venom, which deals d6 acid damage.
Internally, objects for venom exist (to act as the projectiles); however they always disappear upon hitting anything. A wizard mode wish can create them in a more permanent form, however. They are listed under the inventory heading "Venoms", and both appear as "a splash of venom" when unidentified; when thrown, they will have the expected effects.
