When spider is on a stick, it can be cooked. Cooking level 16 is needed. When eaten, the skewer stick returns to inventory, occasionally the spider will heal 100 life points instead, saying "You eat the spider. The meat has a silky texture with a delicate web of flavours". Alternatively an arrow shaft can be used to make spider on shaft however the arrow shaft is not returned to inventory. A spider on stick is needed to be cooked during a medium Karamja Task.
