Spider rod

A spider rod can be used up to three times a day to shoot a strand of spider's silk up to 100 feet (30m). If the strand strikes a creature, there is a chance that it will entangle the creature for up to a minute. The silk is highly flammable, but burning it is likely to cause injury to the entangled creature as well. It is very difficult to cast a spell while entangled. The rod itself is poisonous and can be used in melee combat to inflict this poison. It is worth around 40,000 gold pieces.
