The carcass can be attached to skewer sticks obtained from cutting thatching spars with a Machete, and can then be cooked into spiders on stick. Meanwhile, spiders on shaft can be cooked by attaching the carcass to arrow shafts. Cooking one of these spiders on a stick or shaft is a requirement for the medium tasks in the Karamja diary. This requires a Cooking level of 16. The shafts are destroyed when spider is eaten, while the skewer sticks are reusable.
