Venom

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.

Juiblex and black nagas spit acid venom; guardian nagas and cobras spit blinding venom.

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.
